Super Duplex S32750 Pipes

Meanwhile, these Super Duplex Steel S32760 ERW Pipes are also being offered in different sizes and shapes to our customers. Super Duplex Steel S32750 Round Pipes is not generally suitable for use at temperatures above 300 Degree C as it suffers from precipitation neither of brittle micro constituents, nor below -50 Degree C because of its ductile – to – brittle – transition.

Super Duplex Steel S32760 Square Pipes has excellent general corrosion resistance, and superior to Grade 316 in most environments. Super Duplex Steel S32750 Rectangular Pipes has excellent resistance to localized corrosion including inter – granular, pitting and crevice corrosion. The CPT of Super Duplex Steel S32760 Electropolish Pipes is generally at least 35 Degree C, which further has better resistance to sea water then Grade 316.
