Impact of austenitization temperature on grain size of steel 31CrMoV9

Impact of austenitization temperature on size of austenitic grain of chrome-molibdenum-vanadium steel has been studied. It has been shown that when austenitization temperature is 850-1050ºС, nominal dia. of austenitic grain in the structure of chrome-molibdenum-vanadium steel changes from 0,063 mm to 0,084 mm.   More...
