WebHardening is a metallurgical metalworking process used to increase the hardness of a metal. The process starts with the heating of metal at a critical transformation temperature and quenches in a molten salt bath/water. Hypoeutectoid steels are heated from 30 to 50-degree c above Upper Critical Temperature (UCT), while hypereutectoid steel ...

WebThe hardening of oils and fats by hydrogenation is an important industrial process - with worldwide production of hardened oils in excess of four million tons. Product applications include edible oils, margarine, mayonnaise, frying fats, confectionary, cosmetics, tyres, plastics and many more. The application of this reaction is growing at a ... WebAn oil drying agent, also known as siccative, is a coordination compound that accelerates ( catalyzes) the hardening of drying oils, often as they are used in oil-based paints. This so-called "drying" (actually a chemical reaction that produces an organic plastic) occurs through free-radical chemical crosslinking of the oils.
WebOne of the most common quenchants is the group of hardening oils. Some disadvantages of these are that they are based on mineral oils, are difficult to wash off, and that they constitute a fire hazard. There is ongoing research and development regarding vegetable oils to replace mineral oils as quenchants (18,19).
