Welcome to Golden Steel Material Let’s Talk
ASTM A815 WPS31254 Duplex Stainless Steel Pipe Fittings are premium grade, high-performance components designed for environments demanding exceptional resistance to severe chloride-induced corrosion. Frequently referred to in the industry as 6% Moly or 254 SMO, these fittings are manufactured in accordance with strict ASTM A815 and ASME SA815 specifications. The unique microstructure contains elevated levels of chromium, molybdenum, and nitrogen, giving these WPS31254 buttweld fittings a high Pitting Resistance Equivalent Number (PREN) that guarantees structural longevity in environments far exceeding the capabilities of standard austenitic stainless steels.
Our manufacturing facility supplies a complete inventory of line components, including ASTM A815 WPS31254 elbows, tees, reducers, stub ends, and caps. Available in both seamless and welded configurations, these 6-moly fittings are extensively utilized in offshore oil and gas extraction, desalination plants, marine piping systems, and chemical processing networks. Their high mechanical strength combined with outstanding resistance to stress-corrosion cracking and crevice corrosion ensures highly reliable, leak-proof performance for demanding critical-flow infrastructures.
