To know the production process of stainless steel etching, then we must first talk about stainless steel materials, stainless steel materials have many types, and its characteristics are also different, including product classification SUS310S, 309S, 316L, 316, 316Si, 317, 304, 304L, 309, 305, 31403, 321, 301, 202, 201, etc.. 304 is a commonly used stainless steel material with good corrosion resistance and formability; 301 stainless steel material with high hardness, so it is widely used in higher strength equipment or instruments; 302 contains relatively high carbon content, is a kind of cold-rolled plate, hardness is also very high; 302B contains high silicon content, has a high resistance to high temperature oxidation, with good hot workability Material is mainly 303 and 303Se, these two materials contain sulfur and selenium on different, but easy to cut, higher surface finish. 304L because of the lower carbon content for the need to weld the occasion. Relative to the etched stainless steel production process, commonly used in the material is mainly 304 material, 301 material. And 348 material is a stainless steel suitable for nuclear power industry.

Etching stainless steel production process is a kind of plate exposure, after the development, to be etched in the area of stainless steel part of the protective film removed, in the etching so that the metal contact chemical solution, the use of two positive graphics through the chemical flooding from both sides of the grinding to achieve the effect of dissolution corrosion, the formation of convex or hollow molding effect.

Etched stainless steel production process is used in a relatively wide range of emerging semiconductor industry in the lead frame and integrated circuit bracket are completed by etching process, is an indispensable production process, the field of electronic products on the folding screen, temperature equalization plate are completed by etching stainless steel production process, its automotive field, precision medical instruments are gradually used in our daily life in depth.
