Scope:

This tubing has been used typically for parts 0.75 inch (19 mm) and under in nominal wall thickness at time of heat treatment requiring a through-hardening steel capable of developing hardness as high as 40 HRC when properly hardened and tempered and for parts of greater wall thickness but requiring proportionately lower hardness, but usage is not limited to such applications.

Rationale:

AMS6372N results from a Five-Year Review and update of this specification that revises grain size determination (3.1.1 and 3.3.2), decarburization determination (3.3.4.4), quality (3.4.2), testing frequency (4.2), reporting (4.4) and identification (5.2.1).
