Slotted spring pins heavy duty DIN 1481-stainless steel A2 3x12

The material 1.4310 is an austenitic chrome-nickel steel with good formability. Due to its special mechanical properties, this material is the classic representative of stainless spring steels and is mainly used in the production of corrosion-resistant spring components. The material designation is X10CrNi18-8, X12CrNi177.

Stainless steel refers to alloyed or unalloyed steels that contain at least 10.5% chromium and less than 1.2% carbon. Colloquially, stainless steel is also referred to as stainless steel (NiRo), although not all stainless steel is the same as "stainless".

Stainless steels are defined in DIN EN 10088-1 as iron alloys containing at least 10.5 per cent chromium and no more than 1.2 per cent carbon. The multi-part DIN EN ISO 3506 series of standards applies to mechanical fasteners made from stainless steels. Grade A2 is classified as non-acid-resistant. Austenitic stainless steels cannot be heat-treated and achieve their different strength classes through cold working to varying degrees.
