Abstract
PURPOSE: To enhance strength, stress corrosion crack resistance and corrosion resistance of a two-phase stainless cast steel to seawater by regulating the Cr and Ni contents of said steel to specified quantitative relation.
CONSTITUTION: A two-phase stainless case steel used as a material for a pump, an impeller, a casing, a marine propeller, a propeller shaft, etc. used in seawater is adjusted to a composition having Cr and Ni contents represented by equation y=0.86 x -16o (where y is Ni% and x is Cr%). This austenitic-ferritic two- phase stainless cast steel has high strength, high stress corrosion crack resistance and superior corrosion resistance to seawater.
