Hot-rolled seamless steel pipes and cold-rolled seamless steel pipes are formed by the process of steel or steel plate, they have a great impact on the microstructure and properties of steel, the rolling mill is mainly hot-rolled, cold-rolled only for the production of small steel and sheet. Description:Standard ASTM A106, ASTM A53, API 5L Gr.B, DIN17175, etc Material ASTM A106B, ASTM A53B
Introduction of annealing pickling process for new cold Mar 15, 2018 · The second one is the 2R surface, which is cold rolled and annealed after smooth annealing. Before welding, clean up the paint, dirt and oxide layer of, the former is usually produced by horizontal high yield continuous annealing pickling line, and the annealing of stainless steel strip is carried out in oxidizing atmosphere. The oxidation layer generated in the annealing must be removed
