Properties of 12 Per Cent Chromium Alloys Modified with Small Columbium Additions

Source

A nominal addition of 0.15 per cent columbium to a heat-hardenable 12 per cent chromium stainless steel (Type 410) is without effect on the general corrosion resistance and quenched hardness of this material. The columbium addition produces a refinement in grain size, a reduced susceptibility to temper embrittlement, a mild improvement in resistance to stress-corrosion cracking, a marked improvement in control of tempered hardness, and an increase in the elevated-temperature mechanical strength of the 12 per cent chromium stainless steel.
