Come tradurreste "resistance to temper softening"?

- "Cr (chromium) is an element that increases hardenability, forms carbide, and has effects of strengthening the matrix and improving wear resistance. Cr also contributes to the improvements of the *resistance to temper softening*, and of high-temperature strength. However, excessive addition will cause deterioration of hardenability and high-temperature strength. Therefore, the amount of addition is 3.0 to less than 6.0%, and is preferably not more than 5.65%."

- "V (vanadium) forms carbides and thereby has effects of strengthening the matrix and improving the wear resistance. Moreover, it increases the *resistance to temper softening* and suppresses the coarsening of crystal grains, thereby contributing to the improvement of toughness. Although the amount of addition may be less than 0.5% to achieve these effects, the addition of not less than 0.5% is preferable. However, since excessive addition will cause deterioration of machinability and toughness, a preferable amount of addition is not more than 1.5%."
