1.4568 Stainless Steel Bar
Huien Metal
Product Details
EN 1.4568 SUS631 Cold drawn stainless steel straightening round rod
17-7PH, 631, 1.4568, X7CrNiAl17-7 precipitation hardening stainless steel alloy. It is a semi-austenite, austenite in the annealed state and martensite in the hardened state.
17-7PH provides high strength and hardness, excellent fatigue properties, good resistance to corrosion after heat treatment and minimal deformation. It forms easily in an annealed state and is then hardened to high strength levels by simple heat treatment of conditions RH 950 and TH 1050. Under heat treatment, the alloy provides excellent mechanical properties at temperatures up to 900ºF (482ºC).
Application: Used in aerospace, chemical, petrochemical, paper and metal processing industries.
Ultimate tensile strength: 200 KSI min (1380 MPa min)
Yield strength (0.2% offset) : 175 KSI min (1205 MPa min)
Elongation: 1% min
Hardness: Rc 41 min (target)
