Cold rolled martensitic stainless steel strips in coils AISI 420

 

Martensitic stainless steels, high carbon-chromium, have been developed for a number of applications after cold rolling,

such as razor blades, surgical knives, scissors, cutlery, pressure diaphragms, valve components, bacon slicers and circlips.

 

According to the different carbon content of 420 grade, it can be divided into four categories:

GB  ASTM / SAEJIS   EN / DINCSiMn  Cr    
20Cr13420 ( 420A )

420J1

* The chemical range listed as per EN 10088-2 standard.

 

Hardness comparsion

GradeHardness ( nominal )
420A50 HRC max.
420B53 HRC approx.
420C55 HRC approx.
420D60 HRC approx.

 

420A and 420B stainless steel grades are widely used in medical instruments, economical cutlery / knives,

mechanical parts and components etc.

420C stainless steel is applied in outdoor knives manufacturing, especially like Buck etc.

and our domestic brand Zhangxiaoquan uses this to produce kitchen knives etc.

420D stainless steel is superior to produce razor blades, surgical scalpels, speciality blades etc.

It achieves Rockwell hardness 60 approx. after suitable heat treatment. 

Right now, products for precision cold rolled stainless steel strips in coils W.Nr. 1.4037 ( DIN X65Cr13 ) - AISI 420D

0.1*22.4mm / 16.97mm / 15.4mm are mainly exported to Japan, Germany markets.

 

 

We are specialised in stainless martensitic 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.
