**Stainless Steel 321 and 321H ERW Pipes** are a type of titanium-stabilized austenitic stainless steel, featuring chromium (17–19%), nickel (9–13%), and titanium to boost resistance against carbide precipitation. The 321H grade has a higher carbon content, which enhances its high-temperature strength. These pipes showcase impressive tensile strength (around 515 MPa), yield strength (205 MPa), and good elongation (40%). They also offer excellent oxidation resistance up to 900°C, along with superior formability, weldability, and mechanical stability when exposed to thermal stress.
