Product Description

GB 4Cr13 Annealed Round Bar For Corrosion-resistant Plastic Mould

Product Introduction
GB standard 4Cr13 die/tool steel properties high hardness after quenching than 3crl3 some corrosion resistance. use for the cutting tools, nozzle, value seats and so on. 1crl7Ni2 characteristics and strong resistance to nitric acid corrosion. Use of high hardness and high wear resistance for the heat pumps, valves, valve bearings, medical equipment, springs and other parts.

Features
Medium-carbon high-Chromium martensite stainless steel mould steel
Good mechanical properties, high hardenability, low distortion during heat treatment
Hardness can be obtained up to 48-52HRC with proper heat treatment in order to obtain better polishability, corrosion resistance and wear resistance.
