Passivation is the process of forming a passive layer of chromium oxide on the surface of stainless steel to protect it from corrosion. This is done by adding a chemical that removes free iron and allows chromium oxide to form. The reference for passivation of stainless steel is ASTM A967.

CitriSurf offers top passivation performance to prevent corrosion of stainless steel parts. The most common citric acid solution we see our customers use is CitriSurf 2250. If your specifications are ASTM A380, A967, B600, F983, F86 or others, CitriSurf is very commonly used in the specifications for stainless steel and other alloys. Electropolishing & Passivation Shaw Stainless & AlloyPassivating stainless steel is a process that is performed on the surface of a stainless steel or alloy component. In passivation, the stainless steel spontaneously forms a surface film which makes it more passive or a chemically inactive surface and is non-reactive to air. Electropolishing & Passivation Shaw Stainless & AlloyPassivating stainless steel is a process that is performed on the surface of a stainless steel or alloy component. In passivation, the stainless steel spontaneously forms a surface film which makes it more passive or a chemically inactive surface and is non-reactive to air.
Ultrasonic passivation offers superior rust inhibition as compared to antiquated dip tank methods. Ultrasonic cavitation allows micro-scrubbing of the outer layer of the material, used in conjunction with passivation chemistry, to remove any possibility of oxidation of the stainless steel. NITRIC AND CITRIC ACID PASSIVATION ON STAINLESS Apr 10, 2010 · Passivation is a process to build up a layer of Chromium oxide armour on Austenetic Stainless steel of ships cargo tanks. This mono-molecular oxide layer is about 10 angstroms ( one divided by 10 million-- millimeters ) is invisible , chemically unreactive, self repairing and uni-potentialises the Stainless steel surface. Passivating Services in Wisconsin (WI) on Thomasnet2 days ago · Passivation services are available for stainless steel to ASTM A967, QQ-P-35, AMS 2700 or your company standards. Line is optimized for parts weighing less than one pound each, but larger parts can be done.
Passivation of Aerospace Stainless Steel Parts with Citric Acid Solutions Stephen P. Gaydos, The Boeing Company, St. Louis, Missouri, USA AMS-QQ-P-35 (which replaced federal specification QQ-P-35) is an SAE standard used in the aerospace industry to passivate stainless steel parts. AMS-QQ-P-35 Passivation of Stainless Steel ASTM A967, QQ-P-35, AMS A summary of stainless steel passivation techniques per the common ASTM, AMS and Mil specs is as follows:Passivation of Stainless Steel to ASTM A967. Five nitric and citric methods are listed as follows:Nitric 1:20-25 v% Nitric Acid, 2.5 w% Sodium Dichromate, 120-130F, 20 Mins minimum Passivation of Stainless Steel Brewery, Winery, and Citric acid passivation is by far the best way for a craft or home brewer to passivate their stainless steel tanks. Citric acid is not as harsh as nitric, so it removes iron from the stainless steel surface while leaving behind the chromium and other good stuff.
Pharmaceutical Vessel Manufacturer. SFI is an experienced fabricator of vessels for the pharmaceutical and biopharmaceutical industries. We focused our efforts in 2003 by adding a 15,000 square foot "electropolish bay" to our production facility. Pickling & Passivation Services On-Site & Shop Astro PakAstro Pak has been performing Pickling and Passivation for over 60 years. We pickle steel and other metallic surfaces to remove corrosion and weld damage from steam, heat and other corrosive environments. Our pickling steel process is a non-selective surface treatment that removes oxidation from stainless steel on heavily corroded surfaces. Stainless Steel Tank Suppliers IQS DirectoryStainless steel tanks, silos, frac tanks (mobile, smooth rodless, corrugated rodless), stainless steel storage tanks, round tanks in either vertical or horizontal configuration, stainless steel pressure tanks, production tanks and even a 57-foot-long mobile smoker (for BBQ food) have been built by us.
A worldwide leader in citric acid passivation solutions and other low-hazard products for cleaning and care of stainless steel Passivation of stainless steel has conventionally been accomplished by immersing the steel in a nitric acid bath. This process is both hazardous and environmentally unfriendly. Stellar Solutions has a complete line of stainless steel passivation products for safer and Tremcar Tank trailer & tank truck manufacturerTremcar is a manufacturer of tank trailers and tank trucks for the North American market. Its production output includes stainless steel and aluminum tanks. Tremcar is also specialized in manufacturing vacuum tanks dedicated to cleaning the environment:sanitary sewer, hydro excavation, vacuum sump and other specialized tanks. Why Passivate Stainless Steel and What Happens If You Why Passivate Stainless Steel and What Happens If You Dont By:Patrick H. Banes, Astro Pak Corporation To insure having the maximum corrosion resistance that austenitic stainless steel has to offer, the stainless steel surface must be in a passive state. The passive condition on the surface of the stainless steel is obtained
