Stainless Bright Bars — Manufacturer & Supplier
Corrosion resistance in a machined part — 303, 304/304L, 316/316L, 410, 416, 431 and 17-4 PH.
Stainless bright bar splits two ways. If the part is only machined, 303 and 416 are sulphurised for speed and will turn at close to free-cutting rates. If it has to be welded, 304L and 316L are the grades — the sulphur that helps machining is exactly what cracks a weld. 410 and 431 harden by quenching for stainless parts that also wear, and 17-4 PH ages after machining to past 1300 MPa with almost no distortion. Supplied centreless ground to h8 where the fit is critical.
Manufactured under the Stancor Bright Bars brand by Stancor Bright Bars.
