Acceptance standards of stainless steel products

stainless steel products have acceptance standards, mainly divided into appearance quality requirements, welding requirements and polishing requirements and other three parts.
1. Appearance quality requirements
① The surface of stainless steel products can not have scratches, bumps, crescent marks, etc.;Inspection method: Observe the bottom surface of each stainless steel products, pay attention to the Angle of stainless steel products in the process of turning to hold down the hands to move, watch whether there are crescent marks on the surface of stainless steel products should pay attention to watch along the direction of the light.
The surface of stainless steel products is not allowed to have oil;Inspection method: daily manufacturers to make stainless steel products machinery maintenance and clean, in the placement of semi-finished products, should be placed on the semi-finished products on the board or semi-finished products designated stacked place to avoid stainless steel products surface stained with stains.
2, welding requirements: stainless steel products welding gap to uniform straight, forbidden strong counterpart, the wrong mouth value should be less than 10% of the wall thickness, and not more than 1mm, the specific welding requirements of the following figure
3. Polishing requirements
(1) Stainless steel products in accordance with the polishing product sample comparison and acceptance from the polishing quality, material and product protection three aspects of the test, stainless steel products are not allowed to have blank surface residue, shall not appear elongated deformation phenomenon;
(2) The two surfaces of stainless steel products are vertical, and the right-angle symmetry formed by the two surfaces is maintained after the completion of polishing, and the white surface of residual overheating is not allowed;

③ Stainless steel products are not allowed to have clamping, indentation, bruise, rub flowers, not allowed to have cracks, holes, gaps.

Summary: Although stainless steel products have strong rust resistance and corrosion resistance, but in order to better meet consumer requirements, in the acceptance of stainless steel products in accordance with the acceptance standards to carry out the best, pay attention to carefully observe whether there are cracks on the surface of stainless steel products.
