The use of stainless steel cap

　　The cap is inclined to calculate the thickness plus corrosion allowance, but this thickness does not seem to take into account the hole reinforcement problem, so we are marked in the nominal thickness, followed by: If there is a hole when marked nominal thickness minus Thickness Negative deviation, if only the center of the hole can be marked to calculate the thickness plus corrosion allowance, marked the minimum thickness is mainly to avoid unnecessary cost increases, such as the nominal thickness of 16mm, if the minimum thickness, the cap before forming the blank Can also be used 16mm, if not marked, it may use 18mm of the blank, resulting in increased costs.En 10253-1316 Stainless Steel Pipe Cap blank is subjected to deformation and work hardening during cold forging, allowing the forging to withstand high loads. Therefore, it is necessary to use a high strength forging die and a hard lubricating film treatment method for preventing wear and adhesion. In addition, in order to prevent billet cracks, if necessary, the middle annealing to ensure the required deformation capacity.
