631 (UNS S17700)
631 Precipitation Hardening Stainless Steel
Introduction
UNS S17700
631 (UNS S17700) known also as 17-47 PH is a kind of semi-austenitic
stainless steel with the addition of aluminum, and its composition is similar to that of 18-8 stainless with good performance of metallurgy and manufacturing processes.The hardness of 631 is 37 ~ 43HRC, which can meet some requirements of the parts and plastic mold.
631 (UNS S17700) provides the excellent combination of strength, corrosion resistance and mechanical properties with minimum distortion upon heat treatment.Stainless steel 631 631 (UNS S17700) can gain better wear resistance, anti-bite capacity and service life of mechanical parts after nitriding treatment.
