Lecong Stainless, based in Da Nang, Vietnam, has made a name for itself as a top-notch manufacturer and supplier of high-performance stainless steel products for industrial use around the globe. One of their standout offerings is the Stainless Steel 348 Bars, known for their remarkable resistance to high temperatures and intergranular corrosion. Crafted with cutting-edge production techniques, these bars adhere to rigorous international quality standards. Lecong caters to a wide array of industries, including aerospace, chemical processing, nuclear energy, and power generation. With a solid reputation for precision, durability, and technical know-how, Lecong Stainless provides dependable bar stock solutions designed to meet critical operational needs.
Stainless Steel 348 Bars are made from a columbium-stabilized austenitic stainless steel alloy, typically featuring 17–20% Chromium, 9–13% Nickel, along with trace amounts of Niobium (Columbium) and Tantalum. This unique composition enhances their resistance to intergranular corrosion, particularly after welding. The bars boast impressive mechanical strength, with a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of roughly 35%. Stainless Steel 348 maintains its strength and corrosion resistance even at elevated temperatures, making it an excellent choice for applications that involve significant thermal and mechanical stress.
