ASTM A29 specification is standard specification for Steel Bars, Carbon and Alloy, Hot-Wrought, General Requirements. There are following kind of carbon and alloy steel bars under this standard: hot rolled carbon steel bar, cold finished carbon steel bars, hot rolled alloy steel bars, cold finished alloy steel bars.
Carbon steel bar steel grades like 1020, 1045, 1050 etc. And alloy steel bar common steel grades like 4140, 4340, 5140 etc.
