1.4021 - Martensitic stainless steel / X20Cr13 / AISI 420 / Z20C13 / S42000

Description

Material 1.4021 (X20Cr13 / AISI 420 / Z20C13) – martensitic stainless steel Properties and Applications

The material 1.4021, designated X20Cr13 and commercially known as AISI 420 or Z20C13, is a martensitic stainless steel. It can be hardened and tempered to achieve a wide range of mechanical properties, offering high strength, hardness and wear resistance. Its corrosion resistance is satisfactory in mildly aggressive, water-containing environments but lower than that of austenitic stainless steels. Typical applications include turbine components, pump and valve parts, surgical instruments, cutting tools and automotive or chemical industry components, where hardness, dimensional stability and moderate corrosion resistance are essential.
