Stainless Steel Seamless TubesStainless Steel 904L Welded Pipes
Metinox Overseas is a renowned manufacturer, supplier, stockist, and exporter of ASTM A312 Stainless Steel 904L Welded Pipes. Our range of ASTM A312 TP 904L SS pipes meets various national and international product quality standards. 904L SS, being a low carbon high alloy, finds extensive usage in applications where the oxidation properties of 317L and 316L are insufficient. Notably, the 904L grade is non-magnetic and exhibits excellent weldability, formability, and toughness, owing to its unique composition enriched with elements such as nickel and molybdenum.
The addition of copper enhances the material's resistance against reducing acids like phosphoric and sulfuric acid, while its non-alleviated austenitic nature, coupled with low carbon components, further contributes to its exceptional properties. The presence of nickel and a 6 percent molybdenum element endows 904L with high resistance against oxidation crevice, making it suitable for a variety of demanding environments. Moreover, copper content augments its resistance to sulfuric acid, albeit displaying low resistance to nitric acid.
