Non-magnetic austenitic alloy steels.

摘要

A non-magnetic austenitic alloy steel capable of producing the magnetic properties required in items such as Drill Collars in the as-rolled or as-rolled and direct quenched condition.

The steel composition includes by weight up to 0.5% carbon from 10 to 25% manganese, upto 20% chromium, not less than 0.2% nitrogen and from 0. 2% nitrogen and from 0.2 to 2.0% vanadium.
