Stainless Steel 904L Pipe Fittings are primarily made up of iron, chromium (19–23%), nickel (23–28%), molybdenum (4–5%), and copper (1–2%), which gives them exceptional resistance to corrosion and pitting in harsh environments. On the mechanical side, they boast a tensile strength of 485–620 MPa, a yield strength of around 215–275 MPa, and an elongation of 30–50%, striking a perfect balance between strength and flexibility. The high levels of nickel and molybdenum enhance their resistance to acids, while the low carbon content helps prevent carbide precipitation during welding, ensuring long-lasting durability and dependable performance in chemical, marine, and high-temperature applications.
