Stainless steel

Stainless steel refers to steels with a particular degree of purity and defined requirements regarding chemical composition. Depending on the alloy, stainless steels can possess different properties. Stainless steel is, however, not always synonymous with corrosion-resistant steel.

No. Stainless steel is not automatically rust-free. Rust-free steels form a group of stainless steels whose alloy composition enables increased corrosion resistance. The actual corrosion resistance depends, amongst other things, on the specific steel grade and the operating conditions.

Yes. Suitable stainless steels can be processed by cold forming. In particular, the formability of the material in question, the desired component geometry and the required degree of forming must be taken into account.

MN Kaltformteile processes, amongst others, X6Cr17 (1.4016), X3CrNiCu18-9-4 (1.4567), X5CrNi18-10 (1.4301), X4CrNi18-12 (1.4303), X2CrNiMo17-12-2 (1.4404) and X15CrNiSi25-21 (1.4845).

The choice of material depends on the requirements of the component in question. Depending on the application, factors such as corrosion resistance, temperature resistance, mechanical properties and formability may be decisive. For cold forming, these requirements must be aligned with the component geometry and the intended forming process.
