一绪言炭素工具钢也叫做高炭工具钢,因为它至少含有0.6％炭。炭素工具钢在所有工具钢中是最便宜的,且容易冶炼、鍜造、和车制,在室温下使用比高速钢还硬。同时由於经硬化虎理后,其硬化层很薄,故当配火(Tempering)时也比较容易。虽然它也有许多缺点,例如在高温之下使用时硬度大为減少,缺乏切削耐久性,且经硬化处理后易生开裂(Crack)、扭转(Warping)、歪曲 INTRODUCTION Carbon tool steel, also known as high carbon tool steel, contains at least 0.6% charcoal. Carbon tool steels are the cheapest of all tool steels and are easy to smelt, cut, and car and harder than HSS at room temperature. At the same time as the hardened tiger, the hardened layer is thin, so when the fire (Tempering) is also relatively easy. Although it has a number of disadvantages, such as greatly reduced hardness when used at high temperatures, lack of cutting durability, and Crack, Warping, distortion after hardening
