X20Cr13 is a martensitic stainless steel of German standard (DIN 17400). Its equivalent materials include China’s 2Cr13, the United States’ 420 (UNS S42000) and Japan’s SUS420J1.

1.4021 (X20Cr13) is a martensitic stainless steel with good mechanical properties and is suitable for manufacturing parts that need to withstand high stresses.

1.4028 steel is often used in the production of cutting and molds, forgings, automobile and aircraft parts, and chemical equipment, etc. Its high surface smoothness and good corrosion resistance are o

The corrosion resistance of 201 is very poor, so the price is much cheaper. And because 201 contains less nickel, the price is lower than 304, so the corrosion resistance is not as good as 304.

1.4028 is equivalent to the American standard "AISI 420", and its implementation standard is EN 10088-3-2014. It has good machinability and high corrosion resistance after heat treatment, polishing pe
