Product Description


Acid pickling surface 321 309 310 317H stainless steel pipe pickled 309s 310s SS pipe

 

Stainless steel in the processing process will appear black, yellow oxide skin, in

order to improve the appearance of stainless steel and corrosion resistance, the

stainless steel after processing must undergo pickling passivation.Remove the

oxide skin after welding and high temperature processing, make the silver bright,

and make the treated surface form a layer of chromium as the main substance of

the oxide film, will not produce secondary oxygen corrosion, achieve the purpose

of passivation, so as to improve the surface corrosion quality of stainless steel

products, prolong the service life of the equipment
