The composition of Stainless Steel 347/347H Welded Tubing includes chromium-nickel austenitic stainless steel that’s stabilized with columbium (niobium). This unique feature helps prevent carbide precipitation and intergranular corrosion after welding. The 347H grade, with its higher carbon content, enhances strength at elevated temperatures and improves creep resistance. Mechanically, these tubes excel in tensile and yield strength, toughness, and oxidation resistance when exposed to high temperatures. Their welded construction guarantees precise dimensional accuracy, uniformity, and structural integrity, all while being cost-effective. This blend of mechanical strength, corrosion resistance, and reliability makes them perfect for demanding industrial applications.
