ASTM A36 Steel Plate Supplier, ASTM A36 Plates & S275JR Structural Steel Plates

ASTM A36 steel plate is a low-carbon structural steel plate manufactured in accordance with the ASTM A36 specifications for structural and fabrication use. It is available in plates and sheets of various thicknesses, which are used for parts that needs to be durable, reliable, weldable, and easy to machine. The low-carbon content in the material states that it can be cut, drilled, bent, and welded without complex manufacturing processes. ASTM A36 plates are used for structural frames, base plates, industrial platforms, storage equipment, construction projects, bridges, support structures, and other engineering applications that require moderate strength and good fabrication properties. They are also applied as a base material for equipment that is to be protected by other materials or surface treatment before service.

ASTM A36 steel plates are primarily composed of iron, with a maximum of 0.25-0.29% carbon, 0.80-1.20% manganese, 0.15-0.40% silicon, up to 0.04% phosphorus, up to 0.05% sulfur, and a minimum copper content of 0.20% when that is required to increase resistance to atmospheric corrosion. The material has a minimum yield strength of 250 MPa, tensile strength of 400-550 MPa, minimum elongation of 20-23%, and modulus of elasticity of about 200 GPa. Density is about 7.85 g/cm³, and the melting point is 1420°C to 1465°C. An ASTM A36 plate is usually manufactured by hot rolling and controlled cooling of the steel plate to achieve uniform mechanical properties. It has good weldability and good machinability, accepts thermal cutting without difficulty, and can be cold formed for many fabrication requirements. The mill scale surface is normally protected with paint, galvanising, or other coatings where corrosion exposure is expected.

ASTM A36 Carbon Steel Plates, ASTM A36 Steel Plates & S275JR Steel Plates

The structural and industrial applications rely on ASTM A36 steel plate due to its predictable mechanical properties, ductility, formability, and ease of fabrication. It is suitable for machine processing, can be welded by conventional methods, and can be used to process fabricated assemblies with regular workshop equipment. These features can minimize the fabrication time and material waste in many projects. Commercial buildings, bridge components, heavy machinery, equipment frames, wind energy support structures, storage tanks, marine fabrication, conveyor systems, trailers, agricultural equipment, and general metal fabrication are all uses for ASTM A36 steel plates. The material is generally coated/painted or galvanized before use when outstanding corrosion resistance is needed for use in outdoor operating environments to increase service life.
