400 Series Stainless Steel Overview, Properties, and

400 Series Stainless Steel. The 400 series group of stainless steels typically have an 11% chromium and 1% manganese increase, above the 300 series group. This stainless steel series tends to be susceptible to rust and corrosion under some conditions although heat-treating will harden them. The 400 series of stainless steels have a higher carbon content, giving it a martensitic crystalline structure 420 Hot Rolled Pickling Stainless Steel Channel Bar ASTM High quality 420 Hot Rolled Pickling Stainless Steel Channel Bar ASTM 201.ASTM202, ASTM 301, ASTM304 from China, China's leading Stainless Steel Round Rod product, with strict quality control Stainless Steel Bright Bars factories, producing high quality Stainless Steel Bright Bars products.

This is especially important when working with a large volume of mixed grades of stainless steel in a single bath, as the greater volume increases the risk

Passivation vs. Electropolishing Stainless Steel

In the past, stainless steel passivation was typically preceded by a pre-cleaning process known as pickling. The pickling solution, made from a hydrofluoric acid mixture, was used for dissolving embedded steel flecks and removing the heat tint and oxide scale. Due to EPA regulations, most companies have eliminated pickling. Pickling & Passivation for Stainless Steel Casting Jul 03, 2017 · To be more professional in producing stainless steel castings, CFS foundry has employees with good working experience in pickling & passivation for stainless steel castings, such as valve castings, pump castings, ect.

Pickling and Passivation of Stainless SteelNov 06, 2017 · Some stainless steel pickling or pickling by adding hydrochloric acid, perchloric acid, ferric chloride and sodium chloride and other chloride-containing corrosive media as the main agent or additives to remove the surface oxide layer, with the exception of grease trichlorethylene such as chlorine-containing organic solvents, from the prevention of stress corrosion cracking is not appropriate.

Pickling and Passivation

Pickling is the removal of any high temperature scale and any adjacent low chromium layer of metal from the surface of stainless steel by chemical means. Where the steel has been heated by welding, heat treatments or other means, to the point where a coloured oxide layer can be seen, there is a chromium depleted layer on the surface of the steel underneath the oxide layer.
