A299GrA steel plate is one of the materials widely used in boiler drums (steam drums) of coal-fired generator sets. Boiler plate HARDOX 400 steel yield strength is mainly used in the head and shell of subcritical boiler drum products. Generally used for various welding parts whose working temperature does not exceed 400°C, such as boiler steam drums, pressure vessels, etc., which require the steel to have a high medium temperature.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. HARDOX 400 steel yield strength, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.

The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, HARDOX 400 steel yield strength, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%.
