The boiler steel plate is used to manufacture various boilers and important accessories. Because the A516 Gr 65 pressure vessel steel sheet boiler steel plate works under the medium temperature (below 350 ° C) and high pressure state, it is not only subject to high pressure, but also to impact, fatigue load and water and air corrosion. The boiler steel plate is required to ensure certain strength and good welding and cold bending performance.Bridge steel plate A516 Gr 65 pressure vessel steel sheet is used for large railway bridge. The bridge steel plate is required to bear dynamic load, impact, vibration, corrosion resistance, etc.
As a new type of coil material, compared with the traditional steel coil, A516 Gr 65 pressure vessel steel sheet, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A516 Gr 65 pressure vessel steel sheet carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some A516 Gr 65 pressure vessel steel sheet alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
