The 304 stainless steel cold drawn tube not only has excellent mechanical properties, but also has outstanding corrosion resistance and can be used as a heat resistant stainless steel. The 304 stainless steel cold drawn tube has good plasticity, toughness and cold workability in solid solution state; it has good corrosion resistance in oxidizing acid and medium such as atmosphere and water. At the same time, its production and usage are very large.
304 stainless steel cold drawn tubes can be welded in different ways during use. After welding, there is no tendency to cause intergranular corrosion. For thick section feet, to maintain intergranular corrosion resistance after welding, post-weld heat treatment is required. If it is not heat treated, it should be changed to 304L stainless steel or stabilized austenitic stainless steel. The cold forming factors affecting 304 stainless steel are many and complicated. In terms of its metallurgical factors, it is mainly the composition of steel, that is, the ratio of chromium equivalent to nickel equivalent, and the elongation in conventional tensile properties is an important indicator.
In order to obtain good cold forming properties of the 304 stainless steel cold drawn tube, it is necessary to control the chromium content and the nickel content therein. 304 stainless steel cold drawn tube is widely used, suitable for deep-drawn parts and acid pipelines, containers and so on.
