Stainless steel square tubes are generally used for instruments or medical devices. Not only are they expensive, but they are also generally used in key equipment and instruments. Stainless steel square tubes are also non-magnetic, but they are magnetic after cold processing, which attracts magnets. If the oil in the emulsion can not be cleaned out in time after being carbonized by high temperature, it will accumulate on the surface of the stainless steel square tube, and the stainless steel rectangular tube will form an indentation after rolling.

Production method of stainless steel square tube

The concept of the stainless steel square tube: the square tube is a steel ingot, and the billet or square tube is processed into various shapes, dimensions and functions that we need through pressure processing. In order to facilitate the production of square pipes, order supply, and do a good job in operation management, they are divided into heavy rail, light rail, large section steel, medium section steel, cold galvanized square tube small section steel, and square tube cold formed section steel.

The stainless steel square tube passes the square tube metal billet through a pair of rotating rolls (various shapes). Due to the shrinkage of the rolls, the material section is reduced and the length is increased. This is a common production method for producing square tubes. Used to produce square tube profiles, plates, and tubes.
