بیشترThe Chinese steels are similar to AUS-8 and 440C. 8Cr13Mov was actually a poorly made attempt to replicate 440C steel. 440C is defined by a range of carbon content, not a single specific composition or maker. The range of carbon content in 8Cr13Mov is lower than that of 440C, so tends to have wear resistance more equivalent to AUS-8.

بیشترReheat the metal to 400 - 800°F. This will leave you with a hardness in the range of Rockwell C55 - 56. Don't go over 800°F at this step, as studies show a decrease in toughness and corrosion resistance caused by higher-temperature tempering. Hold for at least two hours, plus 1 hour per inch of thickness over 2 inches.
