高强度沉淀硬化型不锈钢的特点是:经固溶后,其85％是奥氏体和15％是铁素体。在室温时具有良好的成形性能。这种钢经调节时效后抗拉强度可达120kg/mm~2,而耐硝酸腐蚀性不低于18—8不锈钢;它可在高温400～500℃或零下40℃工作。所
High-strength precipitation hardening stainless steel is characterized by: After solution, it is 85% of austenite and 15% of ferrite. Good formability at room temperature. Tensile strength of this steel after conditioning aging up to 120kg / mm ~ 2, and nitric acid corrosion resistance of not less than 18-8 stainless steel; it can work at high temperatures 400 ~ 500 ℃ or minus 40 ℃.
