Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while RINA grade A floating dock steel steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of RINA grade A floating dock steel steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
ASTM A537 steel is a heat-treated carbon silicon manganese steel plate for ASTM pressure vessels, which is divided into 3 levels A537 CL1, A537 CL2, A537 CL3. RINA grade A floating dock steel, A537 CL1 plates delivery status: normalizing; When the A537 CL1 plate thickness is ≤65mm, the yield strength is ≥345MPa, and the tensile strength is ≥485MPa. When the thickness is 65 - 100mm, the yield strength is ≥310MPa and the tensile strength is ≥450MPa.
