Density of commonly used steel

翻译 The density of commonly used steel is an important physical and chemical parameters to measure the qualityof steel. Generally, the density of steelis 7.8-8.0 g/cm3. The most commonly used steel includes Carbon steel, containing carbon content up to 2.1%, belongs to low alloy steel. It has good machinability, ductility and wear resistance. Alloy steel is widely used in various fields due to its low cost, outstanding performance and wide range of applications. The density of alloy steel is generally 7.7~8.1 g/cm3. Stainless steel is a high alloy steel with a density of 7.90~8.00 g/cm3. It has a higher corrosion resistance than ordinary steel and is often used in the manufacture of medical instruments and chemical equipment. Tool steel is used to manufacture tools such as knives and drills. Its density is 7.73~8.06 g/cm3. It has excellent strength, hardness and wear resistance, but it has poor weldability and low heat resistancet. 一般来说，钢的密度为7.8-8.0克/立方厘米。常用的钢包括碳钢、合金钢、不锈钢和工具钢，它们的密度分别为：碳钢的密度约为7.7 - 8.1 g/cm3，含碳量低于2.1％的低合金钢，具有良好的加工性、延展性和耐磨性；合金钢价格低廉、性能优秀，使用范围广泛，其密度一般为7.7-8.1 g/cm3；不锈钢是一种高合金钢，其密度为7.90-8.00 g/cm3，抗腐蚀性强于普通钢，广泛用于制造医疗仪器和化工设备；工具钢用于制造刀具和钻头等，其密度为7.73-8.06 g/cm3，具有优异的强度、硬度和耐磨性，但焊接性差，耐热性低。
