Circlips for bores standard DIN 472-stainless 1.4122 / 1.4310 20x1 mm

The material 1.4122 is also known as X39CrMo17-1. It is a martensitic stainless steel with high corrosion resistance (not suitable for seawater environments), very good wear resistance and formability. Owing to its exceptional mechanical properties, this material is the classic example of stainless spring steel.

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".
