Can Q460C steel plate be used as Q235 steel plate?
Q460 Q235 is not recommended when using their mechanical properties, the gap is too large, the yield strength of Q460 basically is 2 times that of Q235, the elongation is worse than that of Q235, but the problem is not used alone, if used in combination with other components, the effect is not very good, but also not conducive to the overall structure of the force transfer, like cotton in the wire, when the tensile force, most will function in the small deformation component, with low elongation, brittle fracture, which is why when substitute materials are used as close as possible. If you want to weld, it is even more troublesome, Q460 welding performance is poor, the welding process requirements are high, can not be treated as simple as welding Q235, which is also an increase in cost.
Q460C steel plate is superior to Q235 steel in mechanical performance, but Q235 steel plate has lower cost. Therefore, the steel sheet of Q460C material can be used as a Q235 steel plate without considering the cost.
The mechanical properties of the same structure require that the Q460C can reduce the thickness of the material used and reduce the weight of the structure without changing the mechanical properties, without reducing the strength of the base metal and the service life of the workpiece. Reduce the number of welded structures.High strength steel instead of ordinary low carbon structural steel is the current trend.
Q460B can completely replace the Q235 structureQ460C belongs to low carbon high strength steel! Q235 belongs to the commonly used low carbon structural steel material.
