Steel Bars, Forgings, and Tubing 0.88Cr - 1.8Ni - 0.42Mo - 0.08V (0.28 - 0.33C) (4330 Mod) Consumable Electrode Vacuum Remelted
This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
AMS6340B results from a Five Year Review and update of this specification that revises macrostructure, steel cleaniness, decarburization, and reporting requirements.
