The Stainless Steel 309H Pipe Fittings are primarily made up of chromium (22–24%) and nickel (12–15%), which gives them remarkable resistance to oxidation and corrosion. This alloy also includes controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur to boost its mechanical strength. These fittings showcase impressive tensile strength of about 515 MPa, yield strength of roughly 205 MPa, and good elongation properties. Thanks to their superior heat resistance and structural stability, Stainless Steel 309H is perfect for applications that face high temperatures and thermal cycling.
