Stainless Steel Square


Stainless steel square is a semi-finished product, which is usually processed into bars, such as strips, as well as shaped bars: rails, beams and channels. Stainless steel is also commonly used in civil engineering and construction.


A stainless steel square is made in the same way as a stainless steel circle and hexagon. A billet is hot-formed on a blooming mill. A rolling mill, allows you to crimp stainless steel to 40-120 mm in one pass. It takes from 11 to 20 approaches to get the final result. First, the ingot is heated to 1100-1300°С and fed to the blooming mill. The ingot should be weighed before it is crimped. If necessary, the billet is cut, then sent to the billet mill, where it is rolled into round, square or hexagonal shapes. Horizontal and vertical rolls crimp the steel. They press the steel one at a time to reduce the risk of scrap or damage. After being processed in the billet mill, the blanks are sent to the bar mill. This is where rolling determines the shape and size of the stainless steel square, circle or other product. As soon as the rolling is finished, calibration and the final machining step begins. The calibration is marked with the letters A, B, C, this means high, high and normal calibration accuracy of a stainless circle, square or other stainless steel product. The standard stainless steel section is up to 200 mm in diameter. If Ø > 200 mm, the product is produced with a special order marking.

The final treatment of a stainless steel square (or other stainless steel product) may be mirror, matt, polished or super mirror. It should be noted that the average length of the product is usually two meters, but if necessary the factory can produce a cut to another size. Additionally, the factory can perform perforation or welding of rolled products.
