About Zeron 100
Zeron 100 (UNS S32760) super-duplex stainless steel for sub-sea, oil & gas and chemical service.
Zeron 100 (UNS S32760) is a 25% chromium super-duplex stainless steel with tungsten and copper additions, giving a PREN above 40 and certified resistance to seawater, sour service and acid chloride media. Its 750 MPa minimum tensile strength allows lighter, thinner sections than austenitic grades in subsea and desalination equipment.
Steelco Metal & Alloys stocks Zeron 100 (UNS S32760) in Mumbai, India as a stockist, importer and exporter, and ships to 40+ countries. Every dispatch carries EN 10204 3.1 (3.2 on request) mill test certificates, PMI verification and is open to third-party inspection.
