About the Steel
H13 tool steel is a versatile chromium-molybdenum hot work steel known for its exceptional performance under high thermal and mechanical stress. It offers a unique balance of hardness, toughness, and wear resistance, making it highly resistant to thermal fatigue, cracking, and distortion during heat cycling. H13 maintains its strength at elevated temperatures and responds well to heat treatment, offering long tool life in demanding conditions. Its stable behavior during hardening and excellent resistance to abrasion and impact make it a preferred choice for tooling in hot work environments.
