The specifications of stainless steel angle steel are expressed in terms of side length and side thickness. At present, the domestic stainless steel angle steel specifications are 2-20, and the number of side length centimeters is used as the serial number. Stainless steel angles with the same number usually have 2-7 different side wall thicknesses. The imported stainless steel angles indicate the actual size and thickness of both sides, and indicate the relevant standards. In general, large stainless steel corners with a side length of 12.5 cm or more, medium stainless steel corners with a side length between 12.5 cm and 5 cm, and small stainless steel corners with a side length of 5 cm or less.
GB/T2101—89 (General requirements for section steel acceptance, packaging, marking and quality certificate); GB9787—88/GB9788—88 (Hot-rolled equilateral/unequilateral stainless steel angle steel size, shape, weight and allowable deviation); JISG3192 —94 (shape, size, weight and tolerance of hot rolled section steel); DIN17100—80 (quality standard for or dinary structural steel); ГОСТ535—88 (technical conditions for ordinary carbon section steel). According to the above-mentioned standards, stainless steel angle steel should be delivered in bundles, and the number of bundles and the length of the same bundle should comply with the regulations. Stainless steel angle steel is generally delivered naked, and transportation and storage must be protected from moisture.
