High Hardness and Wear Resistance-Best Steel for Forging Dies

Forging dies require steel with high hardness, хорошая прочность, and strong wear and corrosion resistance, and they are often processed with CNC Machining Services for precision and durability. The following types of steel are commonly used:

Твердосплавные износостойкие пластины1. Matrix Steel

Matrix steel is a special tool steel. Its chemical makeup is similar to the base of high-speed steel.

  • After heat treatment, a matrix structure is formed.

  • High strength and good toughness are provided.

  • It is used for tools that need both твердость и ударопрочность.

2. PM23 Powder High-Speed Steel

PM23 is a type of порошковая металлургия (PM) сталь.

  • Твердость: HRC64–66

  • Steel purity is high, так растрескивание is reduced.

  • Strong wear resistance and toughness are achieved.

  • Commonly used in fine stamping dies.

  • Однако, the price is higher.

3. SKH-9 and DC53 Steel

When die life matters:

  • SKH-9 high-speed steel can be selected.

    • Твердость: HRC62–64

    • High tungsten content improves wear resistance.

  • If cost is a concern:

    • DC53 steel is an option.

    • Твердость: HRC60–63

    • Better wear and corner resistance than Cr12MoV.

4. Tungsten Steel (Твердый сплав)

Tungsten steel is known for its чрезвычайная твердость и высокая износостойкость.

  • It stays hard even at 500°C.

  • At 1000°C, it still keeps high hardness.

  • Also offers strength, прочность, и коррозионная стойкость.

5. CPM-20CV Steel

CPM-20CV is a powder tool steel.

  • Excellent wear and edge retention

  • High corrosion resistance due to chromium

  • Useful ratings:

    • Edge Retention: 8

    • Коррозионная стойкость: 6

    • Grindability: 5

    • Popularity: 4

Плакированная пластинаSteel That Is Both Hard and Wear Resistant

Several die steels offer both hardness and wear resistance. Below are commonly used options:

1. Cr12MoV Steel Plate

Cr12MoV is used in cold work dies.

  • Высокая твердость и износостойкость

  • Good for cutting tools and stamping dies

  • Suitable for hard material processing

2. Cr12MoV Steel

This steel is widely used in cold dies.

  • Excellent wear resistance

  • Maintains cutting performance at high temperatures

3. Нержавеющая сталь

Stainless steel contains chromium and nickel.

  • Offers corrosion and wear resistance

  • Keeps surface finish and mold quality

  • Also has high hardness, which increases die life

4. Cr12 Steel

Cr12 is a cold work die steel с:

  • High carbon and chromium levels

  • Very high hardness after heat treatment

  • Used for bending dies, punching dies, and cutting tools

5. P20 and S136 Steel

  • P20 Steel (2311 Сталь):

    • Pre-hardened

    • Good processing and wear performance

    • Used for mid-size plastic mold parts

  • S136 Steel (4Cr13MoV):

    • High-grade stainless

    • Offers good corrosion resistance

    • Ideal for precision molds
