EN 1.4021 stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. 1.4021 is the EN numeric designation for this material. X20Cr13 is the EN chemical designation.

It has a moderately low embodied energy among the wrought martensitic stainless steels in the database.

The properties of EN 1.4021 stainless steel include five common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN 1.4021 stainless steel to: wrought martensitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

 

X20Cr13 and X30Cr13 steel both belong to the European standard EN10088. As the representative steels of high chromium stainless steels,they both belong to martensitic stainless steels and have good machining performance.

After heat treatment(quenching and tempering),they all have excellent corrosion resistance,polishing properties,and high strength and wear resistance.However, in comparison, on the basis of the same chromium content, X20Cr13 has a lower content, which means that the corrosion resistance is relatively high and the strength is relatively low.The hardness of X30Cr13 is relatively high, and it is more suitable for the manufacture of plastic molds that are subjected to high load, high wear resistance and corrosive media
