Super Duplex Steel UNS S32950 Round Bar

Super Duplex Steel UNS S32950 Round Bar for machining, forging and shaft work, available on MetalMitra in round, square and hex bush to ASTM A276, with mill-certified traceability on every lot.

This range covers round, square, hex and flat sections in bright, black, peeled or forged condition, ready for machine shops and component makers.

UNS S32950 is a nitrogen-enhanced duplex stainless steel with high strength and good resistance to stress corrosion cracking. Super duplex stainless steel combines a balanced austenitic-ferritic microstructure with high chromium, molybdenum and nitrogen content, giving very high strength and excellent resistance to pitting, crevice corrosion and chloride stress corrosion cracking.

Product range

• Round Bars — Bright, black, peeled or centreless-ground rounds.
• Hex & Square Bars — Hex and square sections for turned and machined parts.
• Flat Bars — Flats for fabrication and general engineering.
