PH 15-7 Mo Stainless Steel
Introduction
Overview of PH 15-7 Mo Stainless Steel
Grade PH 15-7 Mo stainless steel, also known as UNS S15700 staonless steel. It comes from the chemical compositions of chromium (15.0%), nickel (7.0%), molybdenum (2.0%), and aluminum (1.10%).
It is a semi-austenitic precipitation hardening steel that provides high strength and hardness, good corrosion resistance, and minimum distortion upon heat treatment.
PH 15-7 Mo exhibits better corrosion resistance than 17-4 PH stainless steel in most environments. PH 15-7 Mo is magnetic in both the annealed and hardened conditions.
PH 15-7 Mo material is used for parts requiring high strength, moderate corrosion resistance where a combination of high mechanical strength with good ductility is required after heat treatment.
Features of PH 15-7 Mo Stainless Steel
- High strength and hardness
