  17‑4PH (AISI 630 / UNS S17400) is a martensitic precipitation‑hardening stainless steel that combines high strength, good toughness, and corrosion resistance in a single grade. It can be heat treated to very high strength levels (H900–H1150 conditions) while still performing well in demanding environments like oil & gas, aerospace, and marine equipment.   To see detailed chemical composition, mechanical property tables, step‑by‑step heat treatment conditions (H900, H1025, H1150, etc.), and real‑world industrial applications, read the full guide here:   Full article on Nifty Alloys:   17–4PH Stainless Steel: Properties, Equivalent, Composition & Applications    

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
