繃簧鋼
Spring steel
繃簧在沖擊、振動或長時間交變應力下運用，所以要求繃簧鋼有高的抗拉強度、彈性極限、高的疲勞強度。在工藝上要求繃簧鋼有必定的淬透性、不易脫碳、表面質量好等。
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.
碳素繃簧鋼即含碳量wc在0.6%～0.9%范圍內的優質碳素結構鋼(包含正常和較高含錳量的)。合金繃簧鋼主要是硅錳系鋼種，它們的含碳量稍低，主要靠添加硅含量WSi(1.3%～2.8%)進步功能；別的還有鉻、鎢、釩的合金繃簧鋼。結合我國資源，并依據汽車、拖拉機規劃新技術的要求，研發出在硅錳鋼基礎上參加硼、鈮、鉬等元素的新鋼種，延長了繃簧的運用壽命，進步了繃簧質量。
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.
軸承鋼
Bearing steel
軸承鋼是用來制作滾珠、滾柱和軸承套圈的鋼。軸承在作業時承受著極大的壓力和摩擦力，所以要求軸承鋼有高而均勻的硬度和耐磨性，以及高的彈性極限。對軸承鋼的化學成分的均勻性、非金屬夾雜物的含量和散布、碳化物的散布等要求都非常嚴厲。
軸承鋼又稱高碳鉻鋼，含碳wc為l%左右，含鉻量wc為0.5%-1.65%。軸承鋼又分為高碳鉻軸承鋼、無鉻軸承鋼、滲碳軸承鋼、不銹軸承鋼、中高溫軸承鋼及防磁軸承鋼六大類。
