Structure and properties of power metallurgy tungsten-free ROM2F3-MP high-speed steel

On optimum alloying of high-vanadium, high-speed steel

“…1 these steels are compared with respect to the content of tungsten and molybdenum on one hand (in accordance with the generally accepted [1 ] equivalent W + 1.5Mo in wt.%) and vanadium on the other hand. They can be divided into three groups, namely, (I) classical steels with a high content of tungsten, molybdenum, and cobalt "reinforced" by the introduction of up to 4-6% vanadium, (11) moderately heat resistant "depleted" steels such as ROM2F3 [8], M3F3 [9], and 95Kh6M3F3T [7] with an endurance no worse than that of steel R6M5 in cutting carbon steel, and (Ill) steels with 9-14% vanadium (and 5% Cr) with a virtual absence of other alloying elements.…”
