A105 Carbon Steel Forged Fittings

A105 is the U.S. ASTM standard number, A on behalf of the ordinary carbon structural steel, pipeline system, generally A105 can replace the 20, but 20 can not completely replace the A105, because the strength difference is still large. But A105 stress corrosion cracking (SCC) resistance is slightly worse than 20.
