The surface quality of stainless steel angle 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 of stainless steel angle steel is also stipulated in the standard, which generally includes items such as curvature, side width, side thickness, top angle, theoretical weight, etc., and stipulates that the stainless steel angle steel must not be significantly twisted.
  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. Since 2010, the specifications of domestic stainless steel angle steels are 2-20, and the number of centimeters on the side length is 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.
