stainless steel EN 1.4021 ( DIN X20Cr13 ) cold rolled sheet
AISI 420 - X20Cr13 - 1.4021 - SUS420J1 is a chrome-alloyedheat treatable steel with medium carbon content which is rust proof.
1.4021 has a good corrosion resistance because of its chrome content in moderate aggressive, non chloric substances like soap, solvents and organic acid.
This material shows its highest corrosion resistance with fine grinded and polishedsurface.
The machinability of 1.4021 is comparable with alloyed heat treatable steels and causes no significant difficulties.
AISI 420 - X20Cr13 - 1.4021 - SUS420J1 can be hardened by holding the temperature between 950°C and 1050° C with a subsequent cooling in air, oil or polymer. The strength of 1.4021 depends on the tempering temperature.
X20Cr13 is usually divided in two heat treatment conditions, QT700 and QT800. This material is used in mechanical engineering and power engineering.
We are specialised in stainless martensitic steels (knife steels), which are primarily used for the production of cutlery and
surgical instruments. products in forms of hot- and cold-rolled sheet, plate, strip, coil and bars.
