A588 Gr B weathering steel plate MS carbon mild steel sheet and plate

For A588 Gr B weathering steel plate ASTM A106 seamless steel pipe could transport fluids or gasses at high temperature and pressure levels, with 3 grades A, B, C, most common used ASTM A106 Grade B A588 Gr B weathering steel plate is widely used in the projects of oil and gas refineries, power plants, petrochemical plants, boilers.

The hardness and impact toughness of precipitation-strengthened wear plates, A588 Gr B weathering steel plate are also improved. For example, the hardness of the wear-resistant plate after precipitation strengthening is 230-300 HBW, and the impact toughness is 140-180. More importantly, the improvement of the above indicators does not bring about a significant decrease in plasticity. The performance of the wear-resistant plate after water quenching at 1100℃, first holding at different temperatures in the middle temperature zone, and then water quenching at 970℃. With the increase of the holding temperature in the middle temperature zone and the extension of the holding time, the number of carbides in the steel increases, and the precipitation strengthening effect increases, resulting in an increase in hardness.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of A588 Gr B weathering steel plate welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
