  • Chinese Professional Carbon Steel Plate – Cold rolled plate production – Derunying

    Chinese Professional Carbon Steel Plate – Cold rolled plate production – Derunying

    Cold rolling is processed from hot-rolled sheets at room temperature. Although the rolling process will heat up the steel plate, it is still called cold rolling. Cold rolling uses hot rolled products as raw materials. Our cold rolled products are all processed after pickling. The finished product needs to be heat treated. The intermediate annealing is to eliminate the work hardening caused by the cold deformation caused by recrystallization, so as to restore the plasticity of the material and...

    Factory Outlets Seam And Seamless Pipe - Straight welded pipe – Derunying

    Steel pipe made of hot-rolled or cold-rolled steel plate or steel strip coil welded in a straight seam at a welding facility. Generally, the welded steel pipe has high precision, uniform wall thickness, high brightness of surface inside and outside the pipe (the surface brightness of steel pipe is determined by the surface of steel plate), and it can be arbitrarily length. Therefore, It embodies its economy and aesthetics in the application of high precision, medium and low pressure fluid. Th...
