Product Description

2Cr13 Stainless Steel Introduction

Chinese 2Cr13 steel (20Cr13) is a martensitic stainless steel with magnetic properties, good corrosion resistance and high hardness in the quenched state.

 

2Cr13 stainless steel is used in a wide range of applications, such as cutting tools, surgical tools, and steam turbine blades, material density is 7.75g/cm3, 2Cr13 is an old representation, the new representation is 20Cr13.

Steel Grade Designation Of 20Cr13 = 2Cr13 Stainless Steel

20 (or 2) - Average carbon content: 20/10,000 (0.2%), old designation is 2/1,000

Cr - Chromium symbol

13 - Average content of chromium: 13%
