Martempering is also known as stepped quenching or interrupted quenching. In this process, steel is heated above the upper critical point (above the transformation range) and then quenched in a hot-oil, molten-salt, or molten-lead bath kept at a temperature of 150-300 °C. The workpiece is held at this temperature above martensite start (Ms ...
Seasoning a cast-iron or carbon steel wok is a common process in Asia and Asian-American culture. While the vegetable oil method of seasoning is also used in Asia, a traditional process for seasoning also includes the use of Chinese chives or scallions as part of the process. [19]
Coke being pushed into a quenching car, Hanna furnaces of the Great Lakes Steel Corporation, Detroit, Michigan, November 1942. In materials science, quenching is the rapid cooling of a workpiece in water, gas, oil, polymer, air, or other fluids to obtain certain material properties.
Tempering is most often performed on steel that has been heated above its upper critical (A 3) temperature and then quickly cooled, in a process called quenching, using methods such as immersing the hot steel in water, oil, or forced-air. The quenched steel, being placed in or very near its hardest possible state, is then tempered to ...
Seasoning is a process by which a layer of animal fat or vegetable oil is applied and cooked onto cast-iron or carbon steel cookware. [14] A proper cast iron seasoning protects the cookware from rusting, provides a non-stick surface for cooking, and reduces food interaction with the iron of the pan. [15]
Pan frying is an oil based cooking technique which is typically used to sear larger cuts of meat or to fully cook thinner cuts. This technique uses a thin layer of heated oil to coat the pan. The oil layer is the method of heat transfer between the burner and the food. Water vapor is a critical component of how pan frying works.
Steel which has a carbon content greater than ~0.25% can be direct-hardened by heating to around 600°C, and then quickly cooling, often by immersing in water or oil, known as quenching. Hardening is desirable for metal components because it gives increased strength and wear resistance, the tradeoff being that hardened steel is generally more ...
A cooking vessel is a type of cookware or bakeware designed for cooking, baking, roasting, boiling or steaming. Cooking vessels are manufactured using materials such as steel, cast iron, aluminum, clay and various other ceramics. [1] All cooking vessels, including ceramic ones, absorb and retain heat after cooking has finished. [2]
