ASTM 434 - EN 1.4113

Essential details
ASTM 434 - EN 1.4113, similar to X6CrMoS17-1, is a stainless steel with excellent soft magnetic properties. Its high molybdenum and its low sulphur content provide a very good corrosion resistance in water, steam and other moderate aggressive media. It provides also a higher resistance against pitting corrosion.

This Steel is mainly used in solenoid valves for pneumatic and hydraulic applications with higher requirements regarding corrosion resistance like in medical equipment.
