What is the difference between the prices of the two different materials, the carbon steel and the stainless steel, for the production of guardrail pipes?
The price of a stainless steel pipe is twice that of a normal guardrailpipe.
Steelmaking - rolling round steel - perforation - cold drawing - cold rolling - bright annealing - inner surface polishing - outer surface polishing - inspection acceptance - packaging into the warehouse.
The main advantages of cold drawingprocess: high production efficiency, convenient product specification and flexible in production; tool equipment and production and structural maintenance of the equipment are relatively simple.
The main disadvantage of cold drawingprocess: the small deformation of the pass, so the processing times are many, the production cycle is long, and the metal consumption is large.
