S690QL carbon steel plate sheet vs A283 Grade C

High temperature (creep temperature above) boiler steel plate, generally indicates low alloy heat-resistant steel S690QL carbon steel plate sheet, the commonly used are chrome molybdenum steel, chrome molybdenum vanadium steel, chrome molybdenum tungsten steel, etc. For example, 15CrMoG and 12Cr1MoVG boiler steel plate in GB713 and gr 22 and gr 91 boiler steel plate in ASME SA387/SA387M. High temperature boiler steel plate S690QL carbon steel plate sheet is mainly used to manufacture high temperature pressure parts such as high temperature header end cover, steam pipe plug plate, etc.

The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The S690QL carbon steel plate sheet, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.

How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, S690QL carbon steel plate sheet, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.
