All the cold rolled processes include a pickling stage. Pickling is the removal of high temperature scale and the adjacent low chromium layer of metal from the surface of stainless steel by chemical means. Pickling will also remove manganese sulphide inclusions and any other contamination on the surface.
far from the stainless steel. Any unwanted chemical reaction can be prevented. Manufacturing Process of Stainless Steel Sheet/Plate:Raw materials are sending to hot rolling units for rolling into different sizes. Hot rolled material is annealing in cold rolled annealing furnace and pickling in acid. 304/304L Stainless Steel AK Steel304/304L STAINLESS STEEL Product Description Type 304 is a variation of the base AK Steel 18-8, with a higher chromium and lower carbon content. The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In some instances Type 304 can be used in the "as-welded" condition.
Dec 13, 2018 · The SAE/ANSI 304 (AISI 304) is the most commonly available and used type of stainless steel.It is also referred to as 18/8 stainless steel, A2 stainless steel (as per the ISO 3506), or 304S15 (as per the British Standard).This is an austenitic chromium-nickel alloy which practically means that it has a very high corrosion resistance.

Annealing stainless steel is critical to certain applications where some added corrosion resistance is desired but machinability and formability are also necessary. Generally, the more complex the alloy, the more difficult the anneal (however, austenitic and some ferritic stainless steel types are easy to anneal).
Annealing stainless steel. Annealing stainless steel is critical to certain applications where some added corrosion resistance is desired but machinability and formability are also necessary. Generally, the more complex the alloy, the more difficult the anneal (however, austenitic and some ferritic stainless steel types are easy to anneal). Technical Data Sheet Bright Annealingcommon stainless steel alloys, the minimum atmosphere quality required is about -40°F (-40°C) on a dew point scale (for hydrogen or argon atmosphere) or less than 10-1 Torr partial pressure of water (for vacuum annealing). Oxygen concentrations are critical whether measured in terms of dew point, which is the custom for annealing in hydrogen or
The present invention relates to a process for pickling hot rolled, hot rolled & annealed, and cold rolled & annealed stainless steel strip in a continuous fashion. The process comprises a series of pre-pickling tanks and pickling tanks, and optionally includes a scrubber-brush tank, a de-smutting tank, a filtration unit and a heat exchanger.Annealing 304 Stainless Steel Suppliers, all Quality Annealing 304 Stainless Steel, Annealing 304 Stainless Steel Suppliers Directory - Find variety Annealing 304 Stainless Steel Suppliers, Manufacturers, Companies from around the World at stainless steel ,stainless steel straw ,stainless steel bottle, Stainless Steel Sheets
