: Critically, SAE J1397 is an Information Report , not a material specification. The data are intended for design guidance and should not be used as absolute requirements for procurement unless specifically agreed upon with a supplier.

SAE standards are revised periodically. As of this writing, SAE J1397 has seen updates in several years, including 1985, 1995, 2007, 2012, and 2020.

Includes data on tensile strength, yield point, elongation, and reduction of area for both hot-rolled and cold-finished bars.

It provides critical temperatures for processes like normalizing , annealing , and quenching to reach specific hardness levels. Common Applications
