Austenitic alloys and reactor components made thereof.

摘要

Austenitic stainless steel alloys having excellent fast neutron irradiation swelling resistance and good post irradiation ductility, making them especially useful for liquid metal fast breeder reactor applications. The alloy contains: from 0.04 to 0.09 wt.% carbon; from 1.5 to 2.5 wt.% manganese; from 0.5 to 1.6 wt.% silicon; from 0.03 to 0.08 wt.% phosphorus; from 13.3 to 16.5 wt.% chromium; from 13.7 to 16.0 wt.% nickel; from 1.0 to 3.0 wt.% molybdenum; from 0.10 to 0.35 wt.% titanium and up to about 0.20 wt.% zirconium.
