With a PREN of around 35, duplex stainless steels are generally more corrosion resistant than 304 (PREN: 19) and 316 stainless steels (PREN: 26), particularly stress corrosion cracking.
Duplex flanges can be manufactured and supplied in a variety of sizes and pressure ratings to meet project specific requirements of our customers. Our duplex pipe and fitting products are widely supplied to many industries including boiler manufacturing, brewing tanks and desalination plants.
Duplex stainless steel pipes and duplex fittings are generally lower in cost, as lower percentage of alloying element is used in the manufacture of duplex stainless steel. The yield strength of duplex stainless steel products is higher compared to austenitic stainless steel products, as a result of which users can purchase relatively lower thickness duplex pipes and duplex fittings.
