Type 15-7MO is a semi-austenitic precipitation-hardening stainless steel that provides high strength and hardness, good corrosion resistance and minimum distortion upon heat treatment. It is easily formed in the annealed condition and develops an effective balance of properties by simple heat treatments. For applications requiring exceptionally high strength, cold-reduced PH 15-7MO® Stainless Steel in Condition CH 900 is particularly useful for applications permitting only limited ductility and workability. This alloy is particularly beneficial for applications requiring high strength at elevated temperatures.
Stainless steel 15-7 Mo As a semi-austenitic and precipitation hardening stainless steel that provides good corrosion resistance, high hardness and strength and minimum distortion on heat treatment. In a heat-treated condition, this alloy offers excellent mechanical properties at temperatures up to 482°C (900°F). Its corrosion resistance is superior to that of the hardenable chromium types.

Striping processing, commonly known as “slitting “, refers to the winding of a metal coil by unwinding, slitting, leveling, winding, and processing into a desired width. Slitting processing is a basic metal processing technology that combines high-quality equipment with skilled craftsmanship. it can be obtained with strict tolerance, perfect surface control , safe packaging as well as fine transportation.

Stainless steel 15-7 Mo can be machined in the hardened conditions. The alloy is then readily welded using common arc and resistance methods. It does not require preheating and post weld annealing. Heat treatment can be carried out at temperatures ranging from 482 to 955°C (900 to 1750°F). This alloy works well with any hot working procedures. Finally, the alloy is annealed for 1 hr at 1038°C (1900°F) and then cooled rapidly.
