Tool&Mould Steel
Tool&Mould Steel
Tool&Mould Steel is a specialized category of alloys engineered for manufacturing high-performance tools, dies, and molds.

Features of Tool&Mould Steel
- High Hardness & Wear Resistance: Enhanced by alloy elements (e.g., chromium, molybdenum, vanadium), it offers exceptional surface hardness and abrasion resistance, ideal for high-load molds and cutting tools.
- Superior Heat Treatment Performance: High hardenability and minimal thermal deformation allow precise mechanical property adjustments via quenching and tempering, meeting complex mold requirements.
- High-Temperature Resistance & Thermal Fatigue Resistance: Maintains structural stability under high temperatures, resisting cracks caused by thermal stress, suitable for high-temperature applications like die-casting molds.
