Mold material is a specialized type of steel used for crafting intricate molds, including cold punching dies and hot forging dies. This material serves as the bedrock of the mold manufacturing industry, playing a pivotal role in defining mold performance. Traditional in nature, mold materials have evolved with advancements in technology, variety, and quality standards. Leading manufacturers like Fushun Special Steel, Great Wall Special Steel, Xingcheng Special Steel, and Hangzhou Steel have propelled the industry forward with state-of-the-art processes and superior products. The progressive development of the mold manufacturing sector consequently enhances industrial products, steering them towards higher sophistication, customization, and added value. Mold steel, the most extensively used material, remains indispensable across a multitude of applications.
Performance Requirements
1. Annealing Processability
Our product boasts a broad spheroidizing annealing temperature range, ensuring low annealing hardness with minimal fluctuation and a high spheroidization rate.
2. Forgeability
Designed for optimal forgeability, it offers low resistance to hot forging deformation, excellent plasticity, a wide forging temperature range, and reduced tendencies for forging cracks, cold cracks, and network carbide precipitation.
3. Oxidation and Decarburization Sensitivity
Exhibits superior oxidation resistance at elevated temperatures, slow decarburization rates, insensitivity to heating mediums, and a low tendency for pitting.
4. Cutting Processability
Enables large cutting volumes with minimal tool wear and produces low surface roughness on machined parts.
5. Hardenability
Achieves a deep hardened layer post-quenching and is compatible with mild quenching mediums.
6. Grindability
Features low relative loss on grinding wheels, high limit grinding capacity without burning, and resistance to wear and grinding cracks under varied conditions.
7. Surface Hardness
Ensures uniform and high surface hardness following quenching.
8. Quenching Deformation and Cracking Tendency
Exhibits minimal volume change, slight shape warping, and low abnormal deformation during conventional quenching with reduced cracking sensitivity, regardless of quenching temperature or workpiece shape.
