EN 1.4568 DIN X7CrNiAl17-7 SUS631 Precipitation Hardening Stainless Steel Strip
DIN 1.4568 is a corrosion resistant stainless steel with good formability in soft condition.
The work hardening is greater than other austenitic stainless steels, similar to 1.4310.
The use of 1.4568 stainless 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.
DIN 1.4568 stainless strip 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).
Precipitation hardening steel, Stainless Chromium – Nickel - Steel
Chemical composition ( typical weight % )
1.4568 stainless is produced as narrow strip ( precision strip ) in the thickness range from 0.1 mm to 3.0 mm.
The possible width is in between 5 mm to 420 mm, Tolerances are in accordance to DIN EN ISO 9445.
Possible conditions for delivery are:
Solution annealed (soft) in accordance to DIN EN 10 088 – part 2, procedure 2R, or work hardened (hard) in
accordance to DIN EN 10151 procedure 2H with tensile strength up to maximum 1800 MPa.
