The Stainless Steel 347 and 347H Welded Pipes are primarily made up of iron, chromium, nickel, and trace amounts of columbium (niobium), along with carbon, manganese, phosphorus, and sulfur. The inclusion of niobium helps stabilize the structure and prevents sensitization during the welding process. These pipes showcase remarkable tensile strength, yield strength, and resistance to high-temperature corrosion. They retain their toughness, ductility, and mechanical stability even at elevated temperatures, with 347H featuring a higher carbon content for improved creep resistance. Their unique chemical makeup and mechanical properties guarantee long-lasting durability and reliable performance in welded applications.
