Supply products

In addition to our warehoused materials, we now already regularly supply the full pipe range in C-steels and nickel alloys – not only in project packages.

We would like to invite you to take a closer look at our general categorisation of the various steel types for more detailed information.

If you cannot find the material you require, we would be pleased to procure the right material to meet your requirements.

Other stainless steels

Stainless steel contains more than 10.5 percent chromium, which must be dissolved in the austenitic or ferritic solid solution. With this high chromium content a protective and dense passive layer of chromium oxide forms on the material surface. Other alloy components such as nickel, molybdenum, manganese and columbium ensure an even higher corrosion resistance or more favourable mechanical properties. (Wikipedia).

Heat-resistant, stainless steels

Heat-resistant steels are used at temperatures ranging from 550°C to 1,150°C. The composition of the heat-resistant steels is selected so that the scale oxide which forms when they are used prevents the diffusion of the alloy elements, which in turn protects them against further scaling.

The main reason for this effect is the chromium element. Aluminium and silicium also play a role in preventing scaling. There are two different steel types; ferritic (alloy with chrome) and austenitic (alloy with chrome + nickel).

Carbon-steels and alloy steels

A steel is regarded as a non-alloy type if it does not contain any element except manganese which exceeds a weight percentage of 0.5. It can be recognised by the designation C (for carbon) followed by a number, which corresponds, to 100 times the average carbon content. (For example C 22).

Another version includes a character code designating its use with a number that indicates 1/10 of its tensile strength in N/mm². (For example ST 37 for non-alloy construction steel with a tensile strength of approx. 370 N/mm²) Alloy steel types with a weight percentage of below 5 are indicated with the number which corresponds to 100 times the carbon content and the chemical symbol for the characteristic elements of this alloy followed by numbers in the sequence of the alloy elements and which indicate the content. (For example 10 CrMo 9-10). If the weight percentage of one of the alloy elements is below 5, the material is also marked with the code character “X”.
