Lecong Stainless, based in Da Nang, Vietnam, is a trusted manufacturer and supplier of top-notch stainless steel products that meet global industrial standards. One of their standout products, Stainless Steel 405 Bars, is crafted for outstanding oxidation resistance and moderate corrosion protection, especially in high-temperature settings. Produced with cutting-edge techniques and rigorous quality checks, these bars are perfect for structural and mechanical applications that demand strength, thermal stability, and formability. Lecong Stainless caters to a diverse array of industries, including automotive, heat treatment, power generation, and petrochemicals, offering customized solutions for both local and international clients.
Stainless Steel 405 Bars are ferritic stainless steel bars primarily made up of 11.5–14.5% Chromium, featuring very low carbon content (≤ 0.08%) and aluminum added to enhance oxidation resistance. While these bars can’t be hardened through heat treatment, they do boast good ductility and weldability. Their mechanical properties include a tensile strength of about 450–550 MPa, a yield strength of around 240 MPa, and an elongation of 20–30%. This alloy maintains its structural integrity during thermal cycling and provides moderate corrosion resistance, making Stainless Steel 405 Bars a great choice for moderately corrosive and high-temperature environments.
