The use of hardware made of 303 stainless steel, long exposure to atmospheric salt, a small part of the product began to rust. Stainless steel material, how can we better resist rust? Here to give you a simple analysis of it!
High-speed cutting austenitic stainless steel 303 is not like other austenite rust resistance results. This is due to sulfur, selenium, tellurium free processing additives, which will be initiated as corrosion. In addition, 303 stainless steel wire needs to be different from the chemical passivation standard, compared with austenitic stainless steel is still advantageous. Austenitic stainless steels, including types 302, 304 and 316, are preferred for salt atmosphere / marine environments.
Through the relevant understanding of the test obtained: to obtain corrosion resistance by specifying a smooth surface finish, thoroughly clean the surface for passivation treatment. The passivation treatment is partially immersed in a 30% nitric acid solution to remove any iron contamination on the surface of the stainless steel which is expected to nucleate and rust. Passivation will also remove any grease during processing to make part more attractive.
We can according to the requirements of customers to create any and all the products of stainless steel products, after-sales passivation of the product if there is a demand to meet.
