ASTM A 285gr.B than hot-rolled carbon steel cold rolled steel ASTM A 285gr.B slightly higher. -
ASTM A516gr70 steel plate is used to manufacture petroleum, chemical, petrochemical, gas separation and storage of gas pressure vessel or other similar equipment steels. -
A516gr65 steel plate is widely used for industrial boiler, pressure vessel, oil, gas and petrochemical industry.More information about A516gr65 steel plate, please see the following: -
ASTM 285gr.C steel Chemical requirement in Product analysis:C%:0.28,Mn%:0.98,P%:0.035,S%:0.035,SI%:0.08-0.45. -
ASTM A516gr70 is an excellent weldable carbon steel choice for pressure vessels and boiler fabrication. -
ASTM A 285gr.C cold rolled plate is at room temperature, the hot-rolled plate processing, although in the process because it makes rolling steel warming, was nevertheless called cold. -
It is composed of (in weight percentage) 0.20% Carbon (C), 1.15-1.50% Manganese (Mn), 0.035% Phosphorus (P), 0.03% Sulfur (S), 0.15-0.50% Silicon (Si), 0.05% Niobium (Nb), and the base metal Iron (Fe).
