Home > Stainless Steel 304/304L Flat Bars
Weston Stainless in Midland, UK, is a reliable stainless steel products supplier offering precision-stamped solutions across multiple industries. Their Stainless Steel 304/304L Flat Bars are fabricated using AISI 304 and 304L stainless steel and are renowned for outstanding corrosion resistance, strength, and versatility. They come in several shapes and sizes, from hot-rolled and cold-rolled to bespoke-cut profiles, to suit applications in structures and industry. Made of austenitic stainless steel, they are extensively employed in construction, automotive, marine, and chemical industries to provide superior durability, machinability, and resistance against oxidation, high temperature, and severe environmental factors.
304/304L Flat Bars Stainless Steels contain 18-20% chromium, 8-12% nickel, 2% manganese, 1% silicon, 0.08% carbon (304), 0.03% carbon (304L), 0.045% phosphorus, and 0.03% sulfur for high corrosion resistance and weldability. Mechanical properties consist of 515 MPa tensile strength, 205 MPa yield strength, 40% elongation, and 90 HRB hardness to ensure strength and flexibility. Physical properties have a density of 8.0 g/cm³, melting point of 1400-1450°C, and thermal conductivity of 16.2 W/m·K, thus well-suited for structural, industrial, and high-temperature uses.

Stainless Steel 304/304L Flat Bars are extensively applied in applications needing strength, corrosion resistance, and durability. They find their typical application in construction, automotive, marine, and chemical industries in structural frames, support brackets, and reinforcement jobs. Their machinability and weldability make them perfect for fabrication, industrial equipment, and manufacturing machinery parts. These flat bars are also applied in railway, shipbuilding, food processing, and petrochemical industry where resistance to oxidation and severe environments is essential. Low carbon in 304L prevents carbide precipitation, and hence, they are applied to high-temperature and corrosive services in many different industries.
Rectangular steel pieces known for high strength, durability and corrosion resistance. It is used in architecture, manufacturing, and construction to support and build.
Rectangular sections with consistent thickness and width, used for structural support and fabrication. They offer high strength, durability, and excellent corrosion resistance.
Pre-drilled slots or holes for easy assembly and installation. They offer high strength and corrosion resistance, suitable for brackets, supports, and custom fabrications.
Gradually decreasing thickness, providing smooth transitions in structural designs. They offer high strength, durability, and corrosion resistance for specialized construction and fabrication.
