This paper also treats with the multiple tempering and single tempering on low tungsten high speed steels. It was clarified that the above facts are evident of them, in which the retained austenite of quenched steels is comparatively stable and of large quantity. The effect of aluminum, vanadium and titanium on the properties of the low tungsten high speed steels were also studied.Read More
