Alloy 20 is an austenitic stainless steel containing less than 50% iron developed for applications involving sulfuric acid. Its corrosion resistance also finds other uses in the chemical , petrochemical , power generation , and plastics industries.

Scope of ASTM A53 Standard ASTM A53 is standard specification for pipe, steel, black and hot dipped, zinc-coated, welded and seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 ...
Alloy 20 (Carpenter 20) is an austenitic stainless steel possessing excellent resistance to hot sulfuric acid and many other aggressive environments which would readily attack type 316 stainless. This alloy exhibits superior resistance to stress-corrosion cracking in boiling 20–40% sulfuric acid.
Many material or standard specifications include a number of different UNS numbers that may be used within that specification. For example: UNS S30400 (SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel) could be used to make stainless steel bars ( ASTM A276 ) or stainless steel plates for pressure vessels ( ASTM A240 ) or pipes ( ASTM A312 ).
A woman who has sat in prison for more than a decade was released Tuesday after new evidence contradicted accounts that she helped a hitman take out an innocent victim 25 years ago in the Bronx.
The alloy number is simply a general classifier, whereas it is the specification itself that narrows down the steel to a very specific standard. The SAE steel grade system's correspondence to other alloy numbering systems, such as the ASTM-SAE unified numbering system (UNS), can be seen in cross-referencing tables (including the ones given below).
