It is mainly divided into two types: equilateral stainless steel angle steel and unequal side stainless steel angle steel. Among them, unequal side stainless steel angle steel can be divided into unequal side thickness and unequal side thickness. The specifications of stainless steel angle steel are expressed by the dimensions of side length and side thickness. At present, the domestic stainless steel angle steel specifications are 2-20, and the number of centimeters on the side length is used as the number. The stainless steel angle steel of the same number often has 2-7 different side thicknesses. Imported stainless steel angles indicate the actual size and thickness of both sides and indicate the relevant standards. Generally, those with a side length of 12.5cm or more are large stainless steel angles, those with a side length between 12.5cm and 5cm are medium-sized stainless steel angles, and those with a side length of 5cm or less are small stainless steel angles.It is applied to outdoor machines in the chemical, coal, and petroleum industries that require high grain boundary corrosion resistance, heat-resistant parts of building materials, and parts that have difficulty in heat treatment 1.
