Definitions for "Sensitization"
the process of becoming easily hurt or affected by exposure to or the possibility of being exposed to a hazardous substance.
Immune process whereby individuals become hypersensitive to substances, pollen, dandruff, or other agents that make them develop a potentially harmful allergy when they are subsequently exposed to the sensitizing material (allergen). RT allergy, hypersensitivity.
Enhancement of the strength of a reflexive response produced by the presentation of a noxious stimulus.
In austenitic stainless steels, the precipitation of chromium carbides, usually at grain boundaries, on exposure to temperatures of about 550 to 850oC (about 1000 to 1550oF), leaving the grain boundaries depleted of chromium and therefore susceptible to preferential attack by a corroding (oxidizing) medium.
The condition resulting from heating, or slow cooling, austenitic stainless steels in the temperature range of 800 F to 1600 F (427 C to 871 C), which permits the formation of chromium carbides at the grain boundaries. The formation of carbides reduces the chromium content at the surface of the grains, thereby, reducing corrosion resistance.
The phenomenon in austenitic stainless steels that causes a change to occur in the grain boundaries when heated in the general range of 850 to 1475 degree F. This change destroys the passivity in these locations.
