Tool steel sits at the heart of modern manufacturing, shaping everything from automotive parts to plastic components and forged products. Grades like O1, D2, H13, M2, A2, and S7 each balance hardness, toughness, wear resistance, and heat resistance differently, so choosing the wrong one can mean premature tool failure and costly downtime.   To understand the main tool steel categories (cold‑work, hot‑work, high‑speed, shock‑resisting), compare popular grades in one table, and learn how to match properties like hardness, toughness, and machinability to your application, read the full guide here:   Ultimate Guide to Tool Steel: Grades, Properties & Applications    

Choosing the right tool steel can be the difference between long‑lasting, reliable tooling and premature failure on the shop floor. Grades like D2, O1, and H13 each offer a different balance of wear resistance, toughness, heat resistance, and machinability, so using the wrong one can drive up downtime and tooling costs.   To understand the main tool steel families (cold‑work, hot‑work, high‑speed, shock‑resisting), see how D2, O1, and H13 compare in one table, and get clear guidance on which grade to use for punches, dies, molds, and cutting tools, read the full guide here:   Tool Steel Grades Explained: D2, O1, H13 & More  

  P20 and P20S are two of the most common tool steels used in plastic  mould  making, but they are not interchangeable. P20 offers better  polishability  and high‑gloss surface finish, while P20S adds  sulphur  for easier machining on large or complex  moulds .   To compare their chemical composition, mechanical properties, surface finish, ideal applications, and equivalents in one place—and to see when to choose P20 versus when P20S is the smarter production choice—read the full guide here:   P20 vs P20S Tool Steel: Choosing the Right Grade for Mould Making
