DIN EN ISO 4957 is a standard that specifies general requirements for flat and long products of hot-work tool steels, cold-work tool steels, plastic mold steels, shock-resisting steels, and high-speed steels.

Under this standard, the following are some typical steel grades for each category of steel:

  1. Hot-work tool steels: These steels are used at high temperatures and are highly resistant to heat and wear. They include grades like 1.2344 (H13), 1.2343 (H11), and 1.2365 (H10).
  2. Cold-work tool steels: These steels are used at room temperature and provide a high level of strength, hardness, and wear resistance. They include grades like 1.2379 (D2), 1.2080 (D3), and 1.2842 (O2).
  3. Plastic mold steels: These steels are used to make molds for plastic injection and have good polishability and machining properties. They include grades like 1.2311 (P20), 1.2312 (P20+S), and 1.2738 (P20+Ni).
  4. Shock-resisting steels: These steels are designed to resist shock at both low and high temperatures. They include grades like 1.2767 (NiZ3), and S1, S5, and S7 tool steels.
  5. High-speed steels: These steels are used in cutting tools and are designed to withstand high heat and retain their hardness. They include grades like 1.3343 (M2), 1.3247 (M42), and T1.

Otai can supply all above tool steel in top quality and fast lead time.
