Duplex steel casting - Import export

Duplex UNS S31803/1.4462 is a duplex stainless steel with approximately 50% ferrite and 50% austenite. This grade has good mechanical strength at room temperature, resistant to corrosive attack, including pitting and is resistant to stress corrosion cracking. The grade is a successful alternative to the normal 300 series austenitic stainless steels, where its higher strength and resistance to stress corrosion cracking is required in critical applications. Please note that we have a minimum order value of £10,000.

Our NORSOK-approved Super Duplex alloy 2507 tubes (UNS 32750) are custom-engineered for the most aggressive subsea and downhole oil and gas applications. Advantages include: NORSOK-approval Made to order in specialist non-standard sizes Superior strength and corrosion resistance Short lead times Small batch sizes With 80 years engineering expertise, we specialise in manufacturing corrosion resistant Super Duplex tubes for the increasing hostile temperature and operating environments. Greater Corrosion Resistance Than Standard Duplex Grades Super Duplex stainless like S32750, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that Super Duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades. Please note that we have a minimum order value of £10,000.
