SAE AMS Standard List: Forging Materials

Abstract

A numeral index system is used to identify the compositions of the SAE steels, which makes it possible to use numerals that are partially descriptive of the composition of material covered by such numbers. In the case of the simple alloy steels, the second digit generally indicates the approximate percentage of the predominant alloying element.

This article contains a list of standards that covers among other things:

  • Steel bars & tubing
  • Premium quality aircraft materials
  • Consumables for forging

 

For more information on the SAE AMS designation system see Introduction to the SAE AMS Standard Designation System.
