SKD61 Hot Work Tool Steel | H13 Equivalent Die Steel for Aluminum Die Casting
Product Description:
SKD61 is a high-performance hot work tool steel widely used in aluminum die casting, extrusion dies, and forging molds. It is equivalent to H13 (AISI standard) and offers excellent thermal fatigue resistance, toughness, and wear resistance. SKD61 performs stably under high temperature and pressure conditions and is ideal for high-speed mold applications.
Key Features:
Excellent Hot Strength – Suitable for continuous thermal cycling
High Toughness & Wear Resistance – Prevents cracking and deformation
Good Hardenability – Uniform hardness after heat treatment
Air Cooling Capability – Reduces distortion during quenching
High Polishability – Supports high-precision molding surfaces
Available Sizes:
Round Bar: Dia 20mm – 500mm
Flat Bar / Plate: Thickness 10mm – 300mm
Custom cutting and milling service available
