Mold material is a specialized type of steel utilized in crafting molds, such as cold punching and hot forging dies. It serves as the foundational material and technical bedrock of the mold manufacturing industry. With its variety, specifications, and quality profoundly influencing mold performance, mold material is an indispensable traditional resource. Recently, the production and technological advancements of medieval molds have seen substantial growth, supported by prominent enterprises such as Fushun Special Steel, Great Wall Special Steel, Xingcheng Special Steel, and Hangzhou Steel. This progress has steered the mold manufacturing sector towards sophistication, customization, and high added value. Molds, renowned for their wide applications, utilize a diverse range of materials, with mold steel being the most prevalent.
Performance Requirements
1. Annealing Processability
The spheroidizing annealing should display a broad temperature range, maintain a low and stable annealing hardness, and ensure a high spheroidization rate.
2. Forgeability
The material should exhibit low resistance to hot forging deformation, excellent plasticity, a wide forging temperature range, minimal tendencies towards forging or cold cracks, and resistance to network carbides precipitation.
3. Oxidation and Decarburization Sensitivity
High resistance to oxidation at elevated temperatures, a slow decarburization rate, insensitivity to heating media, and low susceptibility to pitting.
4. Cutting Processability
Capable of large cutting volumes with minimal tool wear and maintaining low surface roughness during machining.
5. Hardenability
Achieves a deeper hardened layer post-quenching and can be effectively hardened using mild quenching media.
6. Grindability
Features minimal grinding wheel loss, substantial non-burning grinding capacity, low sensitivity to grinding wheel quality and cooling conditions, and resistance to abrasion and grinding cracks.
7. Hardenability
Ensures uniform, high surface hardness post-quenching.
8. Quenching Deformation Cracking Tendency
Exhibits minimal volume change, slight shape distortion, and low abnormal deformation tendency during conventional quenching, coupled with low sensitivity to quenching temperature and workpiece geometry.
Application
Mold steel plates are integral in numerous industries, including automotive, electronics, home appliances, plastics, and medical devices. These sectors demand molds that exhibit exceptional strength, hardness, wear resistance, and corrosion resistance.
1.In automotive manufacturing, mold steel plates are pivotal in producing stamping, injection, and die-casting molds, which require stringent mold specifications.
