The main characteristics of mold steel include high hardness, high wear resistance, high strength and toughness, corrosion resistance, good thermal conductivity, easy processing and plasticity.
High hardness and wear resistance: Mold steel can achieve extremely high hardness, usually between HRC 50-65 or even higher, after specific heat treatment and alloying process. This high hardness enables mold steel to maintain stable shape, reduce wear and extend service life during long-term, high-intensity cutting, stamping and die-casting.
High strength and toughness: Mold steel not only has excellent hardness, but also has high strength and toughness. This strength enables mold steel to withstand huge mechanical stress and impact force, while toughness ensures that it is not easy to break or damage under complex working conditions. Corrosion resistance: Mold steel can still maintain good corrosion resistance in harsh working environments, such as high temperature, humidity, acid and alkali conditions. This enables mold steel to resist the erosion of corrosive media in injection molding, die casting and other processes, ensuring the accuracy and stability of the mold.
Good thermal conductivity: Mold steel has good thermal conductivity and can quickly conduct heat to avoid thermal stress concentration and deformation at high temperatures. This feature allows mold steel to maintain stable size and shape during high-temperature processing and improve product processing accuracy.
Easy processing and plasticity: Mold steel has good processing performance and plasticity, which is convenient for cutting, forging, heat treatment and other processing processes. This allows mold steel to adjust its shape and size according to specific needs to meet the manufacturing requirements of different molds.
