17-7PH UNS S17700 Cold Rolled Stainless Steel Sheet SUS631 Strip Condition C

Precipitation hardening steel W.-nr. 1.4568 DIN X7CrNiAl17-7, AISI 631, UNS S17700, 17-7PH

is a corrosion resistant steel with good formability in soft condition.

The work hardening is greater than other austenitic stainless steels, similar to 1.4310.

The use of stainless 1.4568 is indicated, if stress applied parts were exposed to higher temperatures

or if spring parts have to be formed in soft condition with additional hardening.

Please contact our technicians for details.

For machining high quality tooling is required, like for all stainless steels. Polishing is possible.

1.4568 stainless supplied in annealed condition shows low magnetism witch increases with cold forming.

In hard condition: Highly stressed spring parts. Spring parts exposed to higher temperature.

In soft condition: Spring parts which have to be formed in soft condition (spring back effect).
