Influence of chemical composition on the structure of cast K13 type steel

Influence of chemical composition on the structure of cast K13 type chromium steel containing 12-13%Cr is studied. The possibility is shown to change essentially the character of microstructure- ferrite/austenito ratio, their mutual disposition and a rate of solid solution alloyage and a value of chemical microheterogeneity varying within small limits C, Mn, Si, and some other elements contents. It allows one to affect the whole complex of mechanical, technological, and operation characteristics of K13 type chromium stainless steel
