Product Description

Common carbon steel plate: there are four types according to the carbon contained in Q**5, namely Q**5A, Q**5B, Q**5C, Q**5D. Application of Q**5B: To ensure **0? impact power, it can withstand shock loading in use compared with Q**5A. Q**5B is a kind of A3 steel, with low carbon, generally reaching the grade of 4.8. It includes metal framing member, carburization or cyaniding parts with less demanding center intensity, bar, rod, hook, coupler, bolts, nuts, sleeves, shafts and welding parts. The impact experiment should be *0? below. Application of Q**5C: It includes metal framing member, carburization or cyaniding parts with less demanding center intensity, bar, rod, hook, coupler, bolts, nuts, sleeves, shafts and welding parts and can be used in the important welded structure. The impact experiment should be 0? below. Application of Q**5D: It includes metal framing member, carburization or cyaniding parts with less demanding center intensity, bar, rod, hook, coupler, bolts, nuts, sleeves, shafts and welding parts and can be used in the important welded structure. The impact experiment should be **0? below.
