Lightning Bolt is capable of manufacturing a wide range of Alloy-20 flat fasteners including alloy-20 flat washers, alloy-20 lock washers, and alloy-20 belleville washers.
Alloy 20 flat washers, which is also refer to as “carpenter 20” and “20CB-3, is a nickel-chromium-molybdenum stainless steel alloy designed for applications with sulfuric acid. Its corrosion resistance also gives it many other uses within the chemical, food, pharmaceutical, and plastics industries. A main reason why Alloy 20 fasteners are so common is because they resists pitting and chloride ion corrosion and its copper content protects it from sulfuric acid. Cast versions are designated CN7M. Alloy 20 hex bolts, nuts washers, and stud bolts can be fabricated to meet your projects exact requirements. Lightning Bolt specializes in hard to find alloy fasteners, including alloy20 bolts.
ALLOY-20 Flat Washers are made from one of the “Super” stainless steels that was engineered for superior resistance to acid attack. It’s nickel, chromium, molybdenum and copper content contribute to its overall resistance to chlorideon stress corrosion cracking and general pitting attack. It is practically immune to chloride stress corrosion cracking. Alloy-20 is stabilized with columbium to minimize carbide precipitation during welding. It has great mechanical properties and can be fabricated with relative ease.
Though the alloy was designed for use in sulfuric acid related industries, it finds wide usage throughout the chemical industry throughout the world. It also is used for processing pharmaceuticals, food, gasoline, solvents, plastics, explosives, synthetic fibers and many other products.
It has been known to have superior resistance to stress-corrosion cracking in boiling 20 to 40% sulfuric acid. Also, it has excellent general corrosion resistance to sulfuric acid. In addition, it has excellent resistance to chloride stress corrosion cracking. In general this makes alloy 20 an excellent alloy of fastener to use in the chemical industry, Food and dye production industry, SO 2 scrubbers and other severe environments.
