Alloy steels are basically carbon steels with additional elements added to alter the characteristics and bring about a predictable change in the mechanical properties of the alloyed metal. Alloy steels are not normally used for most tools due to their increased cost, but for some have found favor for special applications. The alloying elements used most often in steels are manganese, nickel, molybdenum, and chromium.


Another type of alloy steel frequently used for tooling applications is stainless steel. Stainless steel is a term used to describe high chromium and nickel-chromium steels. These steels are used for tools which must resist high temperatures and corrosive atmospheres. Some high chromium steels can be hardened by heat treatment and are used where resistance to wear, abrasion, and corrosion are required. Typical applications where a hardenable stainless steel is sometimes preferred are plastic injection molds. Here the high chromium content allows the steel to be highly polished and prevents deterioration of the cavity from heat and corrosion.

另一种常常用来制作工具的合金钢是不锈钢。不锈钢是一个描述高铬钢和高镍铬钢的术语。这些钢用来做那些耐高温,耐腐蚀性空气的工具。一些高铬钢能通过热处理硬化,可用于抗磨坏,抗磨损,抗腐蚀需求的地方。可硬化不锈钢的典型应用通常就是塑料注塑模具的首选材料。在这里高的铬含量使钢可以被抛光很多,而不会因为高温和腐蚀而磨损模腔。 马棚网
