绷簧钢
Spring steel
绷簧在冲击、振动或长时间交变应力下运用，所以要求绷簧钢有高的抗拉强度、弹性极限、高的疲劳强度。在工艺上要求绷簧钢有必定的淬透性、不易脱碳、表面质量好等。
When the tension spring is applied under impact, vibration or long time alternating stress, it requires that the tension spring steel has high tensile strength, elastic limit and high fatigue strength. In the process of spring steel requirements have certain hardenability, easy decarburization and good surface quality.
碳素绷簧钢即含碳量wc在0.6%～0.9%范围内的优质碳素结构钢(包含正常和较高含锰量的)。合金绷簧钢主要是硅锰系钢种，它们的含碳量稍低，主要靠添加硅含量WSi(1.3%～2.8%)进步功能；别的还有铬、钨、钒的合金绷簧钢。结合我国资源，并依据汽车、拖拉机规划新技术的要求，研发出在硅锰钢基础上参加硼、铌、钼等元素的新钢种，延长了绷簧的运用寿命，进步了绷簧质量。
Carbon spring steel is carbon content of WC in the 0.6% ~ 0.9% range of high quality carbon steel (including normal and high manganese content). Alloy steel reed steel is mainly silicon manganese steel, their carbon content is slightly lower, mainly by adding silicon content WSi (1.3% ~ 2.8%) progressive function; in addition, chromium, tungsten, vanadium alloy steel spring steel. According to the resources of our country, and according to the requirements of the new technology of automobile and tractor planning, a new kind of steel, such as boron, niobium and molybdenum, is developed on the basis of silicon manganese steel. The service life of the spring is prolonged and the quality of the spring is improved.
轴承钢
Bearing steel
轴承钢是用来制作滚珠、滚柱和轴承套圈的钢。轴承在作业时承受着极大的压力和摩擦力，所以要求轴承钢有高而均匀的硬度和耐磨性，以及高的弹性极限。对轴承钢的化学成分的均匀性、非金属夹杂物的含量和散布、碳化物的散布等要求都非常严厉。
轴承钢又称高碳铬钢，含碳wc为l%左右，含铬量wc为0.5%-1.65%。轴承钢又分为高碳铬轴承钢、无铬轴承钢、渗碳轴承钢、不锈轴承钢、中高温轴承钢及防磁轴承钢六大类。
