Application

ASTM A283 steel plate application:
ASTM A283 steel plate is a low carbon steel that is strong and formable. It is easy to machine and fabricate and can be securely welded by all welding methods. ASTM A283 steel plate is structural carbon steel plate utilized for applications requiring low or intermediate tensile strength. ASTM A283 steel plate is used in the manufacture of storage tanks and low pressure, temperature controlled vessels, riveted, bolted, and welded construction of bridges and buildings, including pre-fabricated buildings, warehouses, and industrial and commercial structures.
