ASTM A283 Standard Specification is for Low and Intermediate Tensile Strength Carbon Steel Plates.
Carbon steel plate A283 Grade A under steel specification ASTM A283/A283 M,they are equal to carbon steel plate SA283 Grade A in steel standard ASME SA 283/SA 283M.Considering the different carbon contains,there are a little difference in yield strength between A283 Grade A.
ASTM A283 GR.A is a kind of common carbon structure steel.The tensile of ASTM A283 is low or mid-low. ASTM A-283/A-283M SA283 has four grades or levels material : A 283 GR.A, A 283 GR.B, A 283 GR.C, A 283 GR.D. ASTM A283 GR.A material we can offer is super heavy steel plates. And the thickness can reach 600mm .
ASTM A283 Grade A Carbon is moderate, has good comprehensive performance, strength, plasticity and welding performance is good, use the most extensively.Often rolled into wire rod or round steel, square steel, flat steel, Angle steel, i-steel, channel steel, steel frame, such as steel, medium plate.A large number of use architecture and engineering structure.
