Martensitic stainless steel

High strength, but poor plasticity and weldability. Commonly used martensitic stainless steel grades 1Cr13, 3Cr13, etc., due to higher carbon content, it has a high strength, hardness and wear resistance, but slightly less corrosion resistance for high mechanical properties, corrosion resistance Requirements of some of the general parts, such as springs, turbine blades, hydraulic valve and so on. This type of steel is used in quenching, tempering treatment. Forging, stamping to be annealed.
