Stainless steel plate refers to the atmospheric, steam and water and other weak medium corrosion steel plate, and acid resistant steel plate refers to acid, alkali, salt and other chemical corrosion medium corrosion plate.Stainless steel plate surface clean, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion.It is an alloy steel that does not rust easily, but not absolutely.
The passivation film on the surface of stainless steel is a barrier to protect the material itself from corrosion.Once the passivation film is damaged locally, the corrosion pit is formed first, and then develops internally, and even corrodes through the whole section.This corrosion is called point corrosion, therefore, in the process of processing stainless steel plate, must protect the surface passivation film, to avoid point corrosion.Its measures include:
1, the storage of stainless steel plate, should be close to the wooden pad, do not stack, to avoid taking steel plate because of drag and scratch steel plate surface.
2, the processing site is best to shop wooden mat board or rubber board, before processing, should remove all iron scraps on the floor, sundries, etc.
3. When marking, it is not allowed to mark and punch with metal marking needle on the surface of the plate, and use pencil or color pen to mark the line.Avoid scratches and keep surfaces clean.
4, the production of complex shape of the accessories, you can first under the template, after checking without error, and then on the stainless steel plate marking.
5, when using manual bite or need to use manual hammer, apply wood and wood hammer.
