What is Alloy 20? I would like guidance on the corresponding American standard material for it.

Thank you~ Alloy 20 is just an abbreviation; what is its grade number?
20 is not an abbreviation; it is the grade itself. . Go and check the mechanical design manual. The carbon content of 20 is 0.2%. The steel grade corresponding to the US standard is 1020
····That’s not 20 Number steel··
ALLOY 20 A351-CN7M?
Also known as Alloy 20#, Carpenter 20Cb3, 0Cr20Ni35Mo3Cu4Nb according to Chinese standards, and N08020 per American standards, as well as Alloy 20cb3, it is a corrosion-resistant alloy with many excellent properties. It offers good resistance to oxidative and moderately reducing corrosion, possesses outstanding resistance to stress corrosion cracking, and good resistance to localized corrosion. It exhibits satisfactory corrosion resistance in a wide range of chemical process media, including highly corrosive inorganic acid solutions, chlorine and various chloride-containing media, dry chlorine gas, formic acid and acetic acid, anhydrides, seawater, and brine. It is characterized by resistance to corrosion in oxidative-reductive composite media. It is used in sulfuric acid environments as well as in sulfuric acid solutions containing halide ions and metal ions, such as in hydrometallurgical processes and sulfuric acid industry installations
The poster is asking about alloy 20. It’s not 20-grade steel!
