Product Description

SKD11 SKD61 1.2344 1.2379 H13 D2 Hot rolled Forged Alloy Tool Steel

1. Product Introduction
High strength at elevated temperatures, high hot wear resistance, good toughness, thermal conductivity and resistant to hot cracking, limited water cooling possible. Applications: Standard material for hot forming tools, extrusion tools, forging dies, pressure casting tools, hot shear knives, tools for plastic industry. Also available in EFS and ESR condition where better properties are required.

2. Features

1. Electroslag remelting steel, high purity, good resistance to dissolve 
2. Organizational structure of uniform, better heat resistance with good toughness, high temperature resistance metal erosion 
3. Good resistance to high temperature tempering performance, hardness steady working under 600ºC, dimensional accuracy stability durability. 
4. Cold and hot fatigue resistance, strong ability to resist crack.
