| Abstraksi | : | Low-carbon, or mild, steels are produced in greater tonnages than all other steels combined. Mild steels is cheap, soft, ductile, and readily welded. However, it cannot be heat-treated. Mild steels are used to produce car bodies, appliance, bridges, tanks and pipe. Low-carbon steels (content 0, 05-0,32%C), which as a rule are readily mcrchinahle, can have their surface layers carburizcd and subsequently hardened. This treatment, called case hardening, gives the steel a hard and wear-resisting surface or case. By virtue of the core remaining comparatively soft and tough the component (is a whole shows high impact strength. Owing to the development of compressive stresses in the surface layers during the case-hardening treatment the fatique strength of the steel is also increased. Carburization is effected either in solid media (carburizing compounds), in salt baths or in gases crt temperatures normally between 825°C and 925°C. The transport of carbon from the carburizing medium always takes place via r. gaseous phase, usually carbon monoxide (CO). The active carburizing agent in a salt bath is sodium cyanide (NaCN,) or potassium cyanide (KCN). It is believed that the carburization proceeds via gaseous phase. The , first reaction takes place at the interface between the salt bath and the atmosphere; the other two reactions take place al the interface between the salt bath and .steel. Some of nitrogen liberated by reaction is also taken up by the steel. |
