Stainless Steel 347 and 347H ERW Pipes are a type of titanium-stabilized austenitic stainless steel, featuring chromium (17–19%), nickel (9–13%), and a touch of titanium to enhance carbide stabilization. The 347H grade has a higher carbon content, which boosts its strength at elevated temperatures. These pipes showcase impressive tensile strength (around 515 MPa), yield strength (205 MPa), and good elongation (40%). They also boast excellent oxidation resistance up to 870°C, along with great formability, weldability, and mechanical integrity even under thermal stress.
