Stainless Steel 347H Pipes are made from high-carbon, stabilized austenitic stainless steel alloys that include chromium, nickel, and niobium. The increased carbon content enhances their strength at high temperatures and improves creep resistance, while niobium helps prevent carbide precipitation during welding and extended heat exposure. In terms of mechanics, these pipes boast excellent tensile and yield strength, good ductility, and superior resistance to thermal fatigue. They maintain their mechanical integrity and oxidation resistance even at elevated temperatures, making them ideal for demanding service conditions.
