Q275A Q275B c section steel
Q275A Q275B parallel flange channel
Q275A and Q275B both belong to a kind of carbon structural steel, high carbon and manganese content, high strength, good plasticity, high NMness and wear resistance, with a certain degree of welding performance and good cutting performance, fully quenched NMness up to HBS270 "400, small parts can be quenched.
Q275A and Q275B are used to manufacture parts with high strength requirements, such as gears, shafts, sprockets, bolts, nuts, profiles for agricultural machinery, conveyor chains and links, as well as a variety of profiles and bars for steel structures.
