EAF-LF-VD-ESR Forged 2. ISO 9001 certificated 3. Factory direct sales steady supply 4. Higher resistance to heat checking Detailed Description Principal Design Features AISI H10 hot work tool steel is a chromium-molybdenum hot work steel that exhibits excellent resistance to softening at elevated temperature. This grade is very resistant to thermal fatigue cracking (heat checking), and can be water cooled in service. Applications H10 is recommended for difficult hot work tooling applications such as hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion tooling.
