Martensitic & PH Stainless Plate — Manufacturer & Supplier
Hardenable stainless for machined, wear and high strength parts — 410, 420, 431, 17-4 PH.
Where a part must be strong, hard and corrosion resistant at the same time, the hardenable grades do the job. 410 and 410S cover valve and pump components; 420 hardens past 50 HRC for blades, moulds and wear plates; 431 adds nickel for marine shafting; and 17-4 PH reaches 1310 MPa tensile from a single low-temperature ageing treatment with minimal distortion, which is why it dominates machined wellhead, aerospace and die work. Supplied annealed for machining, hardened to order.
Manufactured under the Stancor Stainless brand by Stancor Stainless.
