annealed steel; annealed steel (Chromium is principally used as an alloying constituent to increase the corrosion and heat resistance of steel, to increase abrasion resistance in the high-carbon ranges of composition, to increase depth of hardening during heat treatment, and to increase the high-temperature strength of annealed steels. 铬作为合金化组分主要用于提高钢的耐蚀性和耐热性,提高高碳钢的耐磨损性、热处理时的淬硬深度及提高退火钢的高温强度。) | |||
