Smelting Analysis=SA

Finished Product Analysis=FA

①:Applicable to both smelting analysis and finished product analysis.

②:For every 0.01% decrease below the specified maximum carbon content, the upper limit of the specified maximum manganese content can be increased by 0.06%, with a maximum allowable limit of 1.50% for smelting analysis and a maximum allowable limit of 1.60% for finished product analysis.

③:Determined by the 0.2% residual deformation method or the 0.5% elongation under load.

④:For corrections regarding elongation, see standard A-20/A20M.
