Difference Between Duplex and Super Duplex Stainless Steel
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
