The kinematic viscosity, surface tension and resistivity of VNL1, VNL3
and VNL6 steels have been studied. The three steels are quite similar
regarding the chromium, nickel, carbon, silicon and manganese. The di
stinctions are in the levels of molybdenum, copper, niobium and cobalt
. The objective of this work was to study the effect of chemical compo
sition and stucture of the solid metals on the levels and character of
physical property polytherms of steels in the liquid state.
