Tubo de precisão de aço inoxidável de alta resistência ASTM A789 resistente à corrosão
ASTM A789 / A789M covers the requirements for seamless and welded duplex stainless steel tubes for general corrosion-resistant service, with particular emphasis on resistance to stress corrosion cracking. This product combines the excellent toughness of austenitic stainless steel with the high strength of ferritic stainless steel, while offering superior resistance to chloride-induced pitting and crevice corrosion. This product covers common grades including UNS S31803,
UNS S31803 Tubo sem costura ASTM A789 4" Lista 40 Tubo de aço inoxidável
UNS S31803 duplex stainless steel pipe is a widely used duplex grade that offers a balanced mix of good strength, excellent corrosion resistance, and cost-effectiveness. It is the original standard duplex stainless steel, commonly specified in ASTM A790 and ASTM A789 for both seamless and welded pipe applications.With a dual-phase microstructure (austenite + ferrite), UNS S31803 provides approximately twice the yield strength of 304 or 316L austenitic stainless steels, while

Tubo de aço super duplex resistente à corrosão 6.0 mm - 1829 mm OD ASTM A790 A789 A928
Corrosion resistant duplex steel pipe is specifically engineered for service in aggressive environments where standard stainless steels such as 304 and 316 are prone to failure. The unique two-phase microstructure (austenite + ferrite) combined with elevated levels of chromium, molybdenum, and nitrogen provides exceptional resistance to a wide range of corrosive attack mechanisms. Our duplex steel pipes offer outstanding protection against pitting, crevice corrosion, stress
