Material Grades

Element Melting point Importance as alloying element

Aluminium (Al) 658 °C This is the strongest and very frequently used de-oxidation and de-nitriding compound which supports the steel during its ageing. Since Aluminium nitrides with Nitrogen to produce a very hard compound, it is usually used as an alloy in nitriding steel.

Carbon (C) 3450 °C Carbon is the most important and indispensable steel alloying element.

Cobalt (Co) 1492 °C Cobalt is always used together with other alloying elements such as Chromium and Tungsten. It increases the hot hardness and wear resistance in high speed steel.

Chromium (Cr) 1920 °C Chromium forms hard carbides which considerably increase the wear resistance and the durability of cutting edges. At the same time it facilitates through hardening.

Copper (Cu) 1084 °C Copper is used as an alloying element for only a few steel grades because it accumulates below the scale and can penetrate the grain of the steel causing very fragile surfaces in hot forming processes. It is sometimes considered to have a damaging effect on steel.

Manganese (Mn) 1221 °C Manganese binds Sulphur to Manganese Sulphides and thereby reduces the adverse effects of the Iron Sulphide. All steel grades contain small amounts of Manganese in order to facilitate casting, rolling and forging. It is considered an alloying element only if its content is greater than 0.5 percent.

Molybdenum (Mo) 2623 °C Molybdenum is usually used together with other alloying elements. It works like Chromium but is stronger. In combination with Chromium it results in a higher hot hardness.

Nickel (Ni) 1453 °C Nickel gives cold work steels a higher toughness. Engineering steels contain Nickel in combination with Chromium and Molybdenum in order to improve their strength.

Phosphor (P) 44 °C This strong alloying element usually has a damaging effect on steel.

Sulphur (S) 118 °C Sulphur has a low solubility in Iron but forms stable Sulphides with some other alloying elements. Manganese Sulphides are favourable because they have a positive effect on machining.

Silicon (Si) 1414 °C This is included in all steel grades in order to facilitate the processing of the steel. It is considered an alloying element only if its content is greater than 0.5 percent.

Vanadium (V) 1726 °C Vanadium is a good Carbide former. It binds Nitrogen and has a refining effect on the crystals. The result is a finer structure. The hard carbides increase the heat resistance, wear resistance and resistance to tempering.

Tungsten (W) 3380 °C Tungsten forms hard carbides with very good cutting properties and also provides a high hot hardness. The tensile strength, yield strength, wear resistance and toughness can be increased with Tungsten.

Steel of best qualityMeusburger stands for products of finest quality. Steel is delivered from the most famous European steel mills and is being stress-relieved in house with great care. This unique procedure garantees our customers a low warping subsequent machining. Thanks to the temperature being maintained for a long time and slow cooling of the oven at the rate of 35°C/h we obtain the best results in terms of stress-relieved material.

Inside our furnaces with a total capacity of 240 tons, the steel we process is heat treated for stress relief.

Cold-work steelCold-work steel is used for tools that are generally operated at a temperature lower than 200°C. The high alloy cold-work steel grades offer a high wear resistance combined to a good compressive strength. The low alloy grades and those having a low carbon content offer a higher toughness and sufficient compressive strength with a reduced wear resistance.Other noteworthy features are: Economic machinability, cold formability, well polishable and sufficiently resistant against agressive plastics.

Hot-work steelThe permanent operation temperature of hot-work steel is above 200°C. The hot-work steel thus offers best properties for tools designed to process high performance plastics. Further applications are in the field of die casting, extrusion and die forging. The following properties are expected of hot-work steel: high thermal resistance and toughness, high hot-wear resistance and high thermal shock resistance.
