EN 1.4568 DIN X7CrNiAl17-7 Stainless Steel Strip In Coil 17-7PH Plate
Material EN 1.4568 DIN X7CrNiAl17-7, AISI 631, UNS S17700, JIS SUS631
precipitation-hardening stainless steel that provides high strength and hardness, excellent fatigue properties,
good corrosion resistance and minimum distortion upon heat treatment.
It is easily formed in the annealed condition, then hardened to high strength levels by simple heat treatments
to Conditions RH 950 and TH 1050. The exceptionally high strength of Condition CH 900 offers many advantages
where limited ductility and workability are permissable.
In its heat-treated condition, this alloy provides
exceptional mechanical properties at temperatures up to 900°F
(482°C). Its corrosion resistance in both Conditions TH 1050 and RH
950 is superior to that of the hardenable
chromium types. In some environments, corrosion resistance
approximates that of the austenitic chromiumnickel
stainless steels. In Condition CH 900, its general corrosion
resistance is comparable to that of Types 302
and 304 stainless steels.
Fabricating practices recommended for other chromium-nickel stainless steels can be used for this material.
