Steel

Key Features: 1. Exceptional wear resistance (strengthened by chromium, molybdenum, and vanadium carbides) 2. Excellent hardenability (it can be hardened by air cooling) 3. Stable heat treatment performance (minimal distortion) 4. High compressive strength (ideal for punching and molding dies)

Key Features: 1. Exceptional corrosion resistance (it is comparable to 420 stainless steel) 2. Ultra-mirror polishability (it is free from inclusions and porosity) 3. Excellent wear resistance (which is further improved after heat treatment) 4. Low deformation during heat treatment (it is suitable for precision molds)

Key Features: 1. Excellent high-temperature strength (it maintains high hardness even at 600°C) 2. Outstanding thermal fatigue resistance (it is resistant to cracking from thermal cycling) 3. Good temper resistance (stable hardness under high temperatures) 4. Moderate toughness (superior to cold-work steels, like SKD11)

Key Features: 1. High strength and toughness (tensile strength ≥ 980 MPa after quenching and tempering) 2. Good hardenability (chromium enhances heat treatment performance) 3. Moderate wear resistance (which can be improved through surface hardening) 4. Preheating required for welding (prone to cold cracking)

Key Features: 1. Ultra-mirror polishability (achieving polishing grade above #15000) 2. High wear resistance (alloyed with copper and nickel, extending the mold service life) 3. Good texturing performance (suitable for detailed patterning) 4. Supplied in the pre-hardened status (eliminating the need for heat treatment, and reducing deformation risks)

Key Features: 1. Excellent machinability (it can be directly machined in the pre-hardened condition) 2. High polishability (it can achieve mirror finish, suitable for high-gloss molds) 3. Good wear resistance and toughness 4. Uniform microstructure (nickel improves overall performance)

Key Features: 1. High hardness and wear resistance (suitable for enhanced heat treatment) 2. Good machinability (especially in the annealed condition) 3. Limited weldability (preheating and post-weld heat treatment required) 4. High strength, suitable for parts subjected to heavy loads
