304L Stainless Steel Sheet
304L Stainless Steel Sheet
304L stainless steel sheet: The low-carbon version of 304 stainless steel, which resolves the problem of intergranular corrosion after welding of ordinary 304, and has better low-temperature toughness. Application scenarios: Large-scale welded storage tanks / transportation pipelines, food and pharmaceutical welding processing equipment, low-temperature pressure vessels, pure water / water purification systems, coastal building decoration components, weak acid medium chemical equipment.
Product Details
304L stainless steel is a super low-carbon austenitic stainless steel, corresponding to the Chinese standard designation 022Cr19Ni10 (unified numerical code S30403), with a carbon content of ≤ 0.03%. It is a general-purpose corrosion-resistant material and is widely used in fields such as chemical engineering, food processing, and architectural decoration.
Its chemical composition includes 18.0-20.0% chromium and 8.0-12.0% nickel, and through low-carbon design, the anti-intergranular corrosion ability after welding is enhanced. This material has a yield strength of ≥ 205 MPa, tensile strength of ≥ 520 MPa, elongation of ≥ 40%, and combines good formability and low-temperature toughness. During processing, a multi-fire forming process is required to control the deformation amount to avoid grain coarsening caused by high-temperature treatment. As a low-carbon modified version of 304 stainless steel, it is suitable for the manufacturing of welding components and has application advantages in corrosive environments such as heat exchangers and ship equipment.
Properties and Applications of Stainless Steel
As a low-C 304 steel, in general conditions, its corrosion resistance is similar to that of 304 steel, but after welding or stress relief, its anti-intergranular corrosion ability is excellent. Without heat treatment, it can also maintain good corrosion resistance, typically used below 400 (non-magnetic, operating temperature -196 degrees Celsius to 800 degrees Celsius).
It is applied to outdoor machines in chemical, coal, and petroleum industries, as well as building materials, heat-resistant parts, and parts with difficult heat treatment.
The development of 304L stainless steel has made the corrosion resistance, appearance, processing properties, and strength of 304L stainless steel far exceed other materials. Moreover, many surface treatment methods of stainless steel can achieve a rich variety of colors and shapes, which has made a significant contribution to the development of stainless steel.
