Skd61 Steel
Product Description
H13 SKD61 1.2344 Special Alloy Steel Round Bar Hot Work Tool
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.
Features
1.1 Electroslag remelting steel, high purity, good resistance to
dissolve
2.2. Organizational structure of uniform, better heat resistance
with good toughness, high temperature resistance metal erosion
3.3. Good resistance to high temperature tempering performance,
hardness steady working under 600ºC, dimensional accuracy stability
durability.
4.4. Cold and hot fatigue resistance, strong ability to resist
crack.
