Tool steel, description about high carbon high chromium cold work tool steel DIN 1.2379 on China Suppliers Mobile

Product Introduction

DIN 1.2379 is high carbon and high chromium, ledeburitic 12 % Cr alloyed cold work tool steel. Properties: excellent abrasion resistance due to a large volume of carbides in the microstructure, high cutting ability with edge holding properties, high compression strength, excellent deep harden ability and toughness properties, dimensional stability during heat treatment, high res-istance to softening at elevated temperatures. Suitable for nitriding and electrical discharge machining.
