Grade A283Gr.C is under steel specification ASTM A283/A283M for low and intermediate tensile strength carbon steel plates. A283 Grade C carbon steel plate is mainly used for oil tanks for oil and gas companies.A283Gr.C owned min.yield strength at 205Mpa,tensile strength with 380-511Mpa.
Jis g3101 SS400 (Min.yield strength at 245Mpa and tensile strength with 400Mpa-510Mpa).This tensile is very near to A283 Grade C steel plate.
