TTT diagram of isothermal transformations of a hypoeutectoid carbon steel; showing the main components obtained when cooling the steel and its relation with the Fe-C phase diagram of carbon steels. Austenite is slightly undercooled when quenched below Eutectoid temperature. When given more time, stable microconstituents can form: ferrite and ...
English: TTT diagram of the isothermal transformations of a hypoeutectoid carbon steel, together with its relationship with the Fe-C phase diagram of carbon steels. Without exact values, only for educational purposes.
de Buyer (pronounced Duh Bu yeh) is a French cookware manufacturer, founded in 1830, from the village Le Val-d'Ajol in the Vosges department. de Buyer produces around 3,000 different products: cookware made of steel, stainless steel, copper and non stick aluminium, mandoline [ 1 ] slicers, silicone moulds, pastry utensils, etc.
Steel is between 0 and 2.06 mass percent of carbon. Cast iron is between 2.06 and 6.67%. Black lines indicate the metastable Fe/Fe3Cphase, red is the stable Fe/Carbon phase This diagram is for illustrative purposes only, and is not thermodynamically accurate.

Bent's rule can be extended to rationalize the hybridization of nonbonding orbitals as well. On the one hand, a lone pair (an occupied nonbonding orbital) can be thought of as the limiting case of an electropositive substituent, with electron density completely polarized towards the central atom.
The other effect that the seasoning oil has is to make the surface of a cast-iron pan hydrophobic. This makes the pan non-stick during cooking, since the food will combine with the oil and not the pan. It also makes the pan easier to clean, but eventually the polymerized oil layer which seasons it comes off and it needs to be re-seasoned. [1]
Like cast iron, carbon steel must be seasoned before use, usually by rubbing a fat or oil on the cooking surface and heating the cookware on the stovetop or in the oven. With proper use and care, seasoning oils polymerize on carbon steel to form a low-tack surface, well-suited to browning, Maillard reactions and easy release of fried foods.
