General Description

15-7 Mo stainless steel is a semi-austenitic precipitation-hardening stainless steel with molybdenum and aluminum addition. It has high strength and hardness, good corrosion resistance.

Features

  • Strong elasticity, can be repeatedly bent without deformation, The number of reverse stamping reaches tens of thousands.
  • Excellent fatigue strength, high yield strength and close to tensile strength.
  • Working temperature: between 350-500 ℃
  • The best combination of strength and toughness can be achieved by heat treatment, and various cold deformation processing and welding processing can be performed.
