Super Duplex 2507 4410-327-50-E
Super Duplex 2507 is presented here as X2CrNiMoN25-7-4 (4410-327-50-E) under ISO 15510. Chemical composition and designations for stainless steels; a companion reference to product specifications.
ISO 15510 defines chemistry, not plate, sheet or strip mechanical acceptance values. The SS309 and SS310 links identify the ISO compositions shown, rather than claiming all 309/309S or 310/310S variants are identical.
