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

UNS S32760 (Zeron 100) is a super duplex grade with copper and tungsten additions for high strength and seawater corrosion resistance. 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.

Available forms & variants

• 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.
• Forged & Hollow Bars — Forged bars, rings and hollow bars made to order.

Performance highlights

• High Strength — Roughly twice the yield strength of standard austenitic stainless steels.
• Chloride Resistance — Excellent resistance to pitting and crevice corrosion in seawater and brine.
• Stress Corrosion Resistance — Strong resistance to chloride stress corrosion cracking.
• Weight Saving — Higher strength allows lighter designs in suitable applications.
