Mold raw materials

Features of the SKH 9 steel SKH 9 steel is a high-speed tool steel, widely used in various tool manufacturing with its excellent performance. The following are the main features of the SKH 9 steel: Carbide tissue: the carbide tissue of SKH 9 steel is fine, neat, and well distributed and uniform. This structure allows the steel to show a good balance in terms of wear resistance and toughness. High temperature characteristics: By adjusting the carbon content, SKH 9 steel can continuously and substantially change the properties of the steel without damaging its high temperature characteristics, so as to adapt to different application requirements.

SKD 10 steel is a high carbon, high chromium type of lystenite cold-made mold steel, its characteristics include: 12 High hardness: SKD 10 has high hardness, can work in high temperature, high pressure, high load conditions and not easy to wear or deformation.

Corrosion resistance: S136 steel can resist the corrosion effect of water vapor, weak organic acids, nitrates, carbonate, etc., especially suitable for molds that require exposure to these chemicals during the production process.

P20 steel is a kind of hot-working die steel with the following characteristics:
Pre-hard state: P20 steel with pre-hardness range of HRC 25-29, providing uniform hardness and organization. This pre-hard state allows the steel to be used directly for mold processing without additional heat treatment, thus shortening the construction period. Processing performance: P20 steel has good cutting performance, polishing performance and welding repair performance, suitable for polishing and corrosion processing plastic mold processing. After forging and rolling processing, the tissue is dense and can pass 100% ultrasonic test, without stoma or needle hole defects.

DC53 steel is a high-quality cold-work die steel, which has the following characteristics:
Hardness: The hardness of DC53 can reach 62 ~ 63 HRC after heat treatment, which makes it excellent in terms of wear resistance and strength. Toughness: DC53 is twice as resilient as SKD 11, significantly reducing the risk of cracking and cracking, thus improving the service life of the tool. Processing: DC53 can reduce the residual stress after high temperature tempering, thus inhibiting the crack and deformation after wire cutting processing. Performance: DC53 has better cutting and grinding performance than SKD 11, which means that using DC53 can increase the life of the tool mold and reduce the processing process. Application: DC53 is suitable for manufacturing precision stamping die, cold forging die, deep pull mold, etc., and also suitable for high-speed punching punch and stainless steel plate punch.

1. High wear resistance: Cr12MoV steel has a high content of alloy elements, has high hardness and high wear resistance, and can be used for a long time under high stress. 2. High quenability: Cr12MoV steel is easy to form small martensite tissue in the quenching process, which has high quenability and good heat treatment stability. 3. High toughness: Although Cr12MoV steel has high hardness, it also has good toughness and can remain intact under impact load. 4. Good processing performance: Cr12MoV steel has uniform carbide distribution, is easy to process and grind, and can meet the requirements of high precision manufacturing.

718 Steel is a kind of chromium-nickel-molybdenum alloy die steel, with a variety of unique properties and advantages. Its main features include: Pre-hardening treatment.718 steel has been hardened and tempered before leaving the factory, which can not only avoid the deformation risk of quenching and heat treatment, but also can shorten the mold production cycle and reduce the mold cost.
