Carbon steels are used extensively in tool construction. Carbon steels are those steels which only contain iron and carbon, and small amounts of other alloying elements. Carbon steels are the most common and least expensive type of steel used for tools. The three principal types of carbon steels used for tooling are low carbon, medium carbon, and high carbon steels. Low carbon steel contains between 0.05% and 0.3% carbon. Medium carbon steel contains between 0.3% and 0.7% carbon. And high carbon steel contains between 0.7 and 1.5% carbon. As the carbon content is increased in carbon steel, the strength, toughness, and hardness also increase when the metal is heat treated.

碳钢在工具的结构中应用广泛。碳钢指的是只含有铁和碳及少量其它合金元素的金属。碳钢是最常见也是最便宜的一种做工具的钢。用来做工具的三种主要碳钢有:低碳钢,中碳钢和高碳钢。低碳钢的含碳量在0.05%到0.3%之间,(Low carbon steel contains carbon between 0.05% and 0.3%.不知道这样是否正确?)中碳钢的含碳量在0.3%到0.7%之间,而高碳钢的含碳量在0.7%到1.5%之间。随着碳钢中碳含量的增多,金属在热处理时的强度、韧性和硬度也会增加。

Low carbon steels are soft, tough steels that are easily machined and welded. Due to their low carbon content, these steels cannot be hardened except by case hardening. Low carbon steels are well suited for the following applications: tool bodies, handles, die shoes, and similar situations where strength and wear resistance are not required.

低碳钢是软而韧性好的钢,容易加工和焊接。由于它含有较少的碳,这些钢不能被硬化,只能进行表面硬化。低碳钢适用于以下情况:工具机身,把手,模座及其它不要求强度和耐磨性的类似情况。

Medium carbon steels are used where greater strength and toughness is required. Since medium carbon steels have a higher carbon content they can be heat treated to make parts such as studs, pins, axles, and nuts. Steels in this group are more expensive as well as more difficult to machine and weld than low carbon steels.

中碳钢用于对强度和韧性要求较高的地方。由于中碳钢有较高的碳含量,它们可以进行热处理来制作螺栓、插针,轮轴和螺母这样的东西。这种钢比低碳钢贵,也较难加工和焊接。

High carbon steels are the most hardenable type of carbon steel and are used frequently for parts where wear resistance is an important factor. Other applications where high carbon steels are well suited include drill bushings, locators, and wear pads. Since the carbon content of these steels is so high, parts made from high carbon steel are normally difficult to machine and weld.

高碳钢是最能被硬化的一种碳钢,常常用于高耐磨性很重要的地方。高碳钢也很适用的其它地方包括钻头夹头、定位仪和耐磨垫。由于碳在这类钢中的含量很高,用高碳钢制作的零件通常很难被加工和焊接。
