Annealing process of GL-A36 Ro-Ro ship steel plate

This steel standard specification S460 includes four different steel grades GL-A36 Ro-Ro ship steel plate, S460G1+QT, S460G1+M, S460G2+QT and S460G2+M. They have owned different chemical composition and mechanical property. Oil and offshore platform steel plate S460G2+M owned the minimum yield strength at 460Mpa,and the tensile strength shall be within 540-700 Mpa. TMCP heat treatment is necessary for steel plate S460G2+M for any thickness when rolling.

What is the specific use of GL-A36 Ro-Ro ship steel plate, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.

The company formulates appropriate GL-A36 Ro-Ro ship steel plate product internal control components, strictly controls the fluctuation range of chemical components, and ensures the stability of steel plate performance. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate.
