Low alloy steels differ from plain carbon steels in that their characteristic properties are due to elements other than carbon and manganese, e.g. chromium, nickel, molybdenum, etc.

From the above statement, it is obvious that a wide range of steels, having different compositions and heat treatments, are available. Afrox welding consumables are available for welding three types of low alloy steels, with widely varying uses, i.e. creep resisting steels, high tensile steels and steels for use at low temperatures. The welding consumables, steels and procedures for welding these steel types are discussed separately.

Steels for Elevated Temperature Service

Creep is a property of great importance in materials used for elevated temperature applications. Creep is defined as the plastic deformation of steel occurring at an elevated temperature under constant load. Creep is a time dependent failure and occurs at stresses below the yield strength for the particular temperature to which the material is subjected.

Creep occurs in three stages:

• Primary creep (transient stage) – In this stage the creep rate is initially high and gradually decreases due to the effect of work hardening.

• Secondary creep (steady state creep) –The stage inwhich deformation continues at a constant rate, which results from a balance being maintained between the competing processes of work hardening and recovery.

• Tertiarycreep–Ifthestressissufficientlyhighinthisstage, the creep rate accelerates until fracture occurs.

For practical purposes the resistance to creep is expressed by:

• Creep strength -The stress which, at a given temperature and after a given time, causes failure.

• Creep limit -The stresswhich, at a given temperature and after a given time, causes a certain amount of deformation, e.g. 1%.

Creep Resisting Steels

When materials are subject to elevated temperatures, the followingpropertiesareofmajorimportance–theresistanceofthe materials to oxidation and the maintenance of an adequate level of tensile strength and creep resistance. Furthermore, the steels must be capable of operating at these elevated temperatures for an indefiniteperiod. It is awell-known fact that chromiumincreases the strength and oxidation resistance of steel while molybdenum increases the red hardness of steel and its elevated temperaturetensileproperties.Itisnotsurprising,therefore,thatthese two elements are the major alloying additions to these steel types. A wide range of creep resisting steels containing between 0,5 and 1% molybdenum and up to 12% chromium have been developed for use in the power generation and petroleum refining industries.

While the addition of chromium and molybdenum improves the elevated temperature properties of the steel, they also significantlyincreasethehardenabilityofthesteel.Itisthereforeof the utmost importance that these steels be preheated prior to welding and maintained at the preheat temperature for the durationofwelding. Immediately afterwelding, the fabricationsshould be stress relieved before cooling below the preheat temperatures. Typical preheat and stress relieving temperatures are given in the table which follows:

Steels with High Tensile Strength

High tensile alloy steels can be divided into two distinct groups, i.e. the low carbon quenched and tempered or low carbon martensitic types and the high carbon content alloy steels, which transform to high carbon martensite during quenching. In thissection, only the first group will be discussed.

Low Carbon Martensitic Steel Types

The low carbon martensitic steel types exhibit an excellent combination of high strength (yield strength in the vicinityof 700 MPa), toughness, abrasion resistance, excellent HAZstructure resistant to hydrogen-induced cracking coupled with good weldability. These properties have led to steels of this type being used extensively in industries such as earth moving, mining, pressure vessel construction and for military applications.

These steels are low in carbon, e.g. 0,10% to 0,23% and are alloyed with elements such as nickel, chromium, vanadium, molybdenum, boron and in some cases titanium. The elements are balanced carefully to obtain the optimum hardenability and excellent mechanical properties with relatively low cost. In many cases,these steels are sold on the basis of their mechanical properties underawidevarietyofproprietarybrandnamessuchasROQ-TUF, T1, etc.

Hydrogen Cracking

Hydrogen-induced cold cracking, which occurs during the welding of high tensile steels can be divided into two distinct areas:

• Crackingintheweldmetal

• Crackingintheheataffectedzone.

Generally, when the tensile strength of the deposited weld metal exceeds that of the parent material, cold cracking is most likely to occur in the weld metal. These cracks can either be longitudinal centre bead cracks or transverse cracks running perpendicularly through the weld bead into the base material. The direction of the cracks are perpendicular to the stresses imposed upon the joint by restraint and shrinkage of the weld metal during solidification.

Manufacturers of high tensile steels invariably provide adequate data on the preheat and maximum heat input necessary to avoid heat affected zone cracking of the base material.Theserequirementswillbediscussedbrieflybelow.Inmanyinstances,however, the minimum preheat and interpass temperatures may be insufficient to avoid weld metal cracking.

The American Welding Society Structural Welding code D1.1 indicates that preheat and interpass temperatures should be high enough to prevent crack formation in highly restrained joints and provides the following temperatures which should be employed:

Inorderto limitheat input, it is importantthatweldbeadsbedeposited using the stringer technique and that weaving be limitedtolessthan2,5timestheelectrodediameter(i.e.wherethestringerbeadtechniqueisnotpossible).Ageneralguideformaximum heat input values is as follows:

Notes on Welding High Carbon High Tensile Steels

Steels of this type can form very hard structures in the heat affectedzonewhenwelded.Toavoidpossiblecrackingproblems,preheat temperatures up to approximately 300°C may be required, followed in some instances by post weld heat treatment. With regard to these steels, precautions similar to those for carbon- manganese steels should be followed. Steels in this category with a carbon equivalent above 0,5 may be welded with Afrox 309Mo, 312, 98 and 118.

Where high carbon, high tensile steels are to be welded with one of the austenitic type consumables recommended above, a lower preheat temperature would be required.

Notes on Welding Steels for Low Temperature Service

When low temperature steels are to be welded, a number of factors should be kept in mind to ensure the metallurgical integrity of the joint, these are:

• Preheatingisnotgenerallyrequired

• Consumables must be selected which will ensure adequate strength and impact properties at the lowest recommended temperature. In all cases, the consumables should be of the basic coated hydrogen-controlled type

• Excessiveheat inputs shouldbe avoided as thesemay lead to coarse grained weld metal deposits and heat affected zones.Highheat inputpositions such as vertical-up should be avoided where possible.

Afrox Electrodes for Welding Steels for Low Temperature Service

Afrox 76S and Afrox 75 are basic coated hydrogen-controlled 1,0 and 3,5% nickel steel electrodes respectively; suitable for welding carbon-manganese and nickel bearing low temperature steels, suitableforservicedownto-100°C(seeTable8overleaf).

Steels for Low Temperature Service

As the temperature decreases the resistance to impact of steels decreases. This may be gradual in some cases or can occur in a narrow transition band. The ductile to brittle transition of steel, subject to impact loading, is influenced by a number of factors, which include:

• Thecarboncontent–whichshouldbeaslowaspossible

• Thedegreeofdeoxidation–thesteelshouldbefullykilled

• Thegrainsize–shouldbefinegrained

• Thealloycontent–particularlythenickellevel.

A number of these factors can be combined in steels to give the low temperaturenotch toughness required. In some casescarbon manganese steels, such as BS 4360 grades 40E and 43E, have specified minimum impact values at -50°C and below. Nickel bearing steels, however, are normally required to have impact properties at temperatures below -60°C. Acceptance criteria for low temperature steels with regard to impact properties are as follows:

Submerged Arc Fluxes

Afrox HPF-N90 and N90F are semi-basic agglomerated fluxes producing weld deposits with good mechanical properties at low temperatures. HPF-N90 and N90F have excellent weldability, easy slag removal in deep grooves, good resistance to cracking and porosity and excellent bead appearance. HPF-N90 and N90F flux can be used on multi-pass applications on unlimited thickness, with very little change in the chemical composition of the weld metal.

Applications

Afrox HPF-N90 and N90F can be used on structural steel, CrMo steel,highstrength lowalloy (HSLA)steelsandquenchedandtempered steels.The N90F grade has a finer particle size tothe N90 and can be used to rebuild small diameter shafts and journals such as those found on crankshafts.

Storage and Re-drying

The higher the basicity index of agglomerated fluxes, the more hygroscopic such a flux would be. All agglomerated fluxes should therefore be stored in conditions of less than 70% relative humidity. Welding with damp flux can cause porosity.

Re-drying of flux suspected of being moist should be done for approximately two hours at about 300°C at a flux depth of about 25 mm.

Fluxofil M10 is a seamless copper coated metal cored wire with outstanding welding properties in the short arc and spray arc ranges depositing slag free weld metal. Almost spatter-free when welding in the spray arc range. Good restriking, even with a cold wire tip, thus being suitable for robotic applications. Characteristic features: good side wall fusion, smooth and finely rippled welds without undercut into the base metal. Little formation of silicates on top of weld, so that multi-pass welds can be made without

inter-run cleaning. Due to an easily controllable weld pool in the short arc range, Fluxofil M10 is well suited for root and positional welding.

Storage

Keep dry and avoid condensation.

Fluxofil 20 HD is a seamless copper coated rutile flux cored wire and the enhanced degree of fill results in a higher current car-rying capacity and deposition rate. Thus, welding speed may be increased which leads to a saving of time and costs. It can be welded in all positions using only one parameter setting (24 V, wire feed 9 m/min, wire diameter 1,2 mm). Fluxofil 20 HD is also ideal for fully mechanised welding.

The weld metal produced features excellent mechanical-techno-logical properties and a hydrogen content of hydrogen < 5 ml per

100 g deposited weld metal. Low spatter loss, easy slag removal producing finely rippled, pore-free welds without undercut.
