With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
420 is a general purpose medium carbon straight chromium high hardenability martensitic stainless steel with good strength and fairly good corrosion resistance. It is generally supplied hardened and tempered either in the tensile range 700 - 850 Mpa (condition R) Brinell range 201 - 255, or in the tensile range 770 - 930 Mpa (condition S)
Grade 420 stainless steel is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened.

If cutting fluids are allowed to remain on parts that are bright hardened, as in a vacuum furnace or protective atmosphere, surface carburization may occur, leading to a loss of corrosion resistance. Passivating Baths. After thorough cleaning, the stainless steel part is ready for immersion in a passivating acid bath.
Stainless steel is used for jewelry and watches, with 316L being the type commonly used for such applications. Oxidizing stainless steel briefly gives it radiant colors that can also be used for coloration effects. Valadium, a stainless steel and 12% nickel alloy is used to make class and military rings.
But it's the lowest end stainless, meaning it's not as good as the lowest end non-stainless (tool) steel, except in the stain-resisting department. Whenever a knife maker wants to put *some* sort of marketing phrase on their blades, but they do not want to put 420, they will instead put "surgical stainless steel" because that impresses some people.
the type of stainless steel and its metallurgical and physical condition. Because the various stainless steels have different alloy compositions, they can be expected to behave differently when exposed to pickling acids. Also, stainless steel parts that have been sensitized by welding or
Stainless Steel Chemical Compatibility Chart: Check the chemical compatibility of Stainless Steel with various chemicals, solvents, alcohols and other products. Shop Stainless Steel Please Note: The information in this chart has been supplied by reputable sources and is to be used ONLY as a guide in selecting equipment for appropriate chemical 420 bright acid white stainless steel
2004. A. Regarding the corrosion of stainless steel, I would say stainless steel exhibits good corrosion qualities because of the chromium layer formed on it and this chromium which also contributes to one of its major constituents when exposed to brine, or calcium chloride is corroded (rusting can also be the initial outcome).
To fill this need, the Committee of Stainless Steel Producers initially prepared this booklet. The data was reviewed and updated by the Specialty Steel Industry of North America (SSINA). Written especially for design engineers, it presents an overview of a broad range of stainless steels both standard and proprietary their compositions,
Bright Dips. EPi's series of stabilized peroxide bright-dip processes prevent re-tarnishing of brass, leaded brass, and copper after brightening. Chemically polish stainless steel alloys that contain nickel with a formula containing a blend of mineral acids. Learn More
For bright-finish parts that reflect too much glare as in the surgical suite glass beads or a fine abrasive buffing pad may be used to tone down the surface finish. Electropolishing is accomplished by creating an electrochemical cell in which the material to be polished is the anode (stainless steel part).
from the surface of the stainless steel. Mixtures of nitric and hydrofluoric acids are usually used for pickling stainless steels. Pickling is the process used to remove weld heat tinted layers from the surface of stainless steel fabrications, where the steels surface chromium level has been reduced. PICKLING AND PASSIVATING STAINLESS STEEL 2.
Hydrochloric acid and sulphuric acid at some concentrations are particular aggressive towards stainless steel. Stress corrosion cracking (SCC) - This is a relatively rare form of corrosion which requires a very specific combination of tensile stress, temperature and corrosive species, often the chloride ion, for it to occur.
I have tried electropolishing 400 series stainless steels, but they do not develop the highly bright finish that 304 & 316 achieve when electropolished using solutions containing phosphoric and sulfuric acid. I believe the Electropolishing Engineering Handbook lists some formulas for 400 stainless steel electropolishing. Also some of the 420 bright acid white stainless steel
Stainless Steel Pipes - Allowable Pressure - Allowable pressure for standard seamless A312-TP316/316L stainless steel pipes - temperatures 100 o F to 750 o F; Stainless Steel Pipes - Comparing American and European Standards - Comparing American - US - and European - German, British (UK) and Swedish - stainless steel pipe standards
420 J2 is a general purpose stainless steel containing medium quantity of carbon. It has good corrosion resistance qualities in mild atmosphere, domestic and industrial environments. It is resistant to ammonia, blood, carbonic acid, crude oil, detergent solutions, dilute nitric acid, fresh water, food acids, many petroleum products, steam and 420 bright acid white stainless steel
The insides and even the outsides of stainless steel pans can develop white, cloudy spots, like the well-used All-Clad saucepan shown below. These spots come from mineral deposits left in the pan after boiling water, and the white spots can come from both salt and/or calcium deposits.
Home Stainless Grades 400 Series Stainless 430 Stainless Steel 430 Stainless Steel Penn Stainless inventory now includes Alloy 430 (UNS S43000) in sheet, sheet coil, plate, round bar, processed flat bar and tubular products.
Passivation is a chemical process that is used to help restore contaminated stainless steel to original corrosion specifications. Parts are placed in baskets and submersed into a diluted nitric acid or citric acid solution for a specified length of time and temperature.
Stainless steel grade 420J2 is inexpensive and highly corrosion resistant steel. It has good corrosion resistance in mild atmosphere as well as domestic and industrial environments. It is also resistant to dilute nitric acid, carbonic acid, ammonia, crude oil, detergent solutions, vinegar, food 420 bright acid white stainless steel
Many people ask about the differences between nitric acid and citric acid when passivating parts made of stainless steel (SS), titanium (Ti), and other alloys. In the past, manufacturers avoided citric acid due to potential organic growth and molding issues.
stainless steel to take place. Typical compo-sitions involve nitric acid and hydrofluoric acid. Treatment time depends on the tem-perature of the solution and the degree of contamination. Passivating The self-passivation of stainless steel nor-mally takes place spontaneously in the presence of oxygen from air or water.
While a relatively concentrated dose of Starsan, which is a blend of phosphoric acid and dodecylbenzenesulfonic acid, or Bar Keeper's Friend (Do not apply to electrically etched markings), which is oxalic acid, does work to passivate stainless steel, there are a few other options that work equally as well.
stainless for even less resistance reading left to right across the lowest level of corrosion resistance, strength increases progressively from type 409Cb stainless to types 410, 420 and 440C stainless steels Custom 450 stainless, type 431 stainless and Custom 455 stainless are positioned in the middle of the diagram
416 stainless steel. The processing properties of the material are improved by adding sulfur. 420 stainless steel Blade grade martensitic steel, the earliest stainless steel, similar to Brinell high chromium steel. It is also used for surgical cutting tools, which can be very bright. 430 stainless steel
On the bright side, all 420 stainless steel is extremely rust resistant. This means that one of the best uses for this material is to make diving knives because of their constant contact with saltwater. Sometimes, you will also see 420J. 420J is the lowest quality 420 steel, but is also the most rust resistant.
Passivation of Stainless Steel Specifications. Advanced Plating Technologies, offers passivation of stainless steel to all methods listed within ASTM A967, AMS 2700 and QQ-P-35. In addition, APT can meet the requirements of any company-specific nitric or citric acid stainless steel passivation methods.
Insta-Blak SS-370 is a liquid concentrate solution used for swab-on or immersion blackening of stainless steel surfaces.
