High Hardness and Wear Resistance-Best Steel for Forging Dies

Forging dies require steel with high hardness, ketangguhan yang baik, 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:

Plat Pakai Karbida1. 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 kekerasan dan rintangan hentaman.

2. PM23 Powder High-Speed Steel

PM23 is a type of metalurgi serbuk (PM) keluli.

  • Kekerasan: HRC64–66

  • Steel purity is high, so retak is reduced.

  • Strong wear resistance and toughness are achieved.

  • Commonly used in fine stamping dies.

  • Namun begitu, the price is higher.

3. SKH-9 and DC53 Steel

When die life matters:

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

    • Kekerasan: HRC62–64

    • High tungsten content improves wear resistance.

  • If cost is a concern:

    • DC53 steel is an option.

    • Kekerasan: HRC60–63

    • Better wear and corner resistance than Cr12MoV.

4. Tungsten Steel (Aloi Keras)

Tungsten steel is known for its kekerasan yang melampau dan Rintangan haus yang tinggi.

  • It stays hard even at 500°C.

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

  • Also offers strength, keliatan, dan rintangan kakisan.

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

    • Rintangan Kakisan: 6

    • Grindability: 5

    • Popularity: 4

Plat berpakaianSteel 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.

  • Kekerasan tinggi dan rintangan haus

  • Good for cutting tools and stamping dies

  • Suitable for hard material processing

2. Cr12MoV Steel

This steel is widely used in cold dies.

  • Rintangan haus yang sangat baik

  • Maintains cutting performance at high temperatures

3. Keluli Tahan Karat

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 dengan:

  • 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 Keluli):

    • Pra-keras

    • 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
