Explanation

By adding precipitation hardening elements such as aluminum, copper, titanium, niobium and undergoing precipitation hardening treatment, precipitation hardening phase is precipitated from the matrix solid solution of steel to produce precipitation hardening effect, and stainless steel (600 series) with high strength, high toughness and high corrosion resistance is obtained. According to the matrix structure, it can be divided into martensitic precipitation hardening stainless steel, semi-austenitic precipitation hardening stainless steel and austenitic precipitation hardening stainless steel. Due to its high strength, high toughness, high corrosion resistance, high oxidation resistance, good formability and weldability, it is widely used in aerospace, defense and military industry, nuclear power, energy, petrochemical and other industrial sectors.
