Stainless steel flat steel is rectangular steel with slightly pure edges. Stainless steel flat steel can be semi-finished steel. There are cold drawn polished stainless steel flat steel and hot rolled acid white sandblasted stainless steel flat steel.

Stainless steel flat steel can be composed of various stress-bearing components according to different needs of the structure, and can also be used as a connection between components. It is widely used in various building structures and engineering structures, such as building beams, bridges, power transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Types and specifications

It is mainly divided into two types: equal side and unequal side. Among them, the equal side can be divided into square steel. The specifications are expressed by the size of side length and side thickness. The domestic specifications are 3mm*20m—150mm.

Appearance Quality

The surface quality of stainless steel flat steel is stipulated in the standard, and it is generally required that there should be no harmful defects in use, such as delamination, scarring, and cracks.

The allowable range of geometric shape deviation is also specified in the standard, which generally includes items such as curvature, side width, side thickness, apex angle, theoretical weight, etc., and requires significant torsion.

high quality 410 stainless steel is a stainless steel grade produced in accordance with the American ASTM standard, which is equivalent to my country's 1Cr13 stainless steel, S41000 (American AISI, ASTM). 0.15% carbon content, 13% chromium content, high quality 410 stainless steel: has good corrosion resistance, machinability, general purpose blades, valves. 410 stainless steel heat treatment: solution treatment (℃) 800-900 slow cooling or 750 fast cooling.
