Processing characteristics of hot die steel

Hot-work die steel used in the high temperature forging stamping steel, cold and hot steel matrix a new type of high temperature resistance and high strength steel, pure matrix, uniform annealing organization, in all directions has excellent resistance and ductility, good abrasion resistance, excellent heat treatment standard stability, excellent hardenability, excellent temper softening, excellent high temperature resistance, excellent tolerability resistance to thermal fatigue, polishing, with high hardness, high wear resistance and high durability.

Hot die steel shall be of excellent machinability. Due to the complex shape of the plastic mold cavity, the surface quality of the mold cavity is very high, and many parts are not easy to process. Therefore, molded plastic steel should have excellent cutting function. Plastic molded steel shall have excellent wear resistance. When an inorganic material such as fiberglass is added to the plastic assessment, wear on the mould increases and greater wear resistance is required to ensure the mould has a long life.

Hot die steel can be roughly divided into cold die steel, hot die steel and plastic steel. Due to the different use of different molds and complex working conditions, the steel used in the mold should have higher hardness, strength, wear resistance, enough toughness, and according to the working conditions of the mold produced with higher hardenability and hardening. Hardness and other process properties. Due to the different USES and complex working conditions of this type, the performance requirements for the formwork steel are also different.

Vacuum heat treatment technology and equipment have developed rapidly and have been widely used in quenching and tempering cold processing of shapes and products at home and abroad. Some foreign mold manufacturers have used large area chamber and vacuum heat treatment furnace to heat treatment of deformed steel bars and coils. Due to the high quality of vacuum heat treated steel and parts, the material consumption is low and easy to control.
