These Stainless Steel 316H EFW Pipes find their place in various sectors, including chemical, petrochemical, power generation, and marine industries. Irfan Pipes and Tubes ensures prompt delivery and outstanding service, making them a trustworthy partner for essential industrial applications.
Stainless Steel 316H EFW Pipes are austenitic stainless steels that contain 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, featuring a higher carbon content than standard 316 to enhance high-temperature strength and creep resistance. The EFW manufacturing process guarantees precise dimensions and robust weld integrity. Mechanically, these pipes boast high tensile and yield strength, along with excellent toughness and durability under elevated temperatures and high pressure. Their improved chemical composition offers superior resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, making them perfect for challenging industrial settings.
