The Stainless Steel 321H Pipes are composed of chromium (17–19%), nickel (9–12%), and titanium, which provide excellent resistance to oxidation and carbide precipitation at high temperatures. They have a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. The inclusion of titanium enhances their stability against intergranular corrosion. These pipes showcase impressive mechanical strength, hardness, and creep resistance, making them ideal for extended use in high-temperature and corrosive settings.
