Lecong Stainless, based in Da Nang, Vietnam, has built a solid reputation as a manufacturer and supplier of top-notch stainless steel products, providing dependable solutions for essential piping and pressure systems. One of their standout offerings is the Stainless Steel 304/304L Forged Fittings, crafted for exceptional strength, corrosion resistance, and leak-proof performance in both high- and low-pressure settings. These fittings are made using precise forging techniques and high-quality materials, ensuring they meet international standards. Available in various configurations like elbows, tees, couplings, and unions, Lecong caters to key industries such as oil & gas, chemical processing, water treatment, and shipbuilding, consistently delivering quality and long-lasting value.
Stainless Steel 304/304L Forged Fittings are crafted from austenitic stainless steel alloys that contain 18–20% Chromium and 8–12% Nickel. The 304L grade, with its lower carbon content (≤ 0.03%), significantly boosts resistance to intergranular corrosion after welding. These fittings boast impressive mechanical properties, featuring a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of roughly 40%. They also demonstrate excellent toughness and oxidation resistance. Thanks to their strength and weldability, these forged fittings are perfect for high-pressure and corrosive piping systems across various industrial applications.
