A number in parentheses indicates the year of last reapproval. Referenced Documents2. Aecm, Ae1, Ae3, Ae4—See transformation temperature. DISCUSSION—This treatment is used for purposes such as reducinghardness, improving machinability, facilitating cold working, produc-ing a desired microstructure, or obtaining desired mechanical, physical,or other properties.
Where applicable, it is preferred that the followingmore specific terms be used: box annealing, bright annealing, fullannealing, intermediate annealing, isothermal annealing, processannealing, spheroidizing, and subcritical annealing. Any pro-cess of annealing will usually reduce stresses; however, if thetreatment is applied for the sole purpose of stress reduction, it should bedesignated stress relieving. Arcm, Ar1, Ar3, Ar4—See transformation temperature. Current edition approved Nov.
Published December Originallyapproved in Last previous edition approved in as Ab. United States1baking, n—heating to a low temperature in order to removegases. It is used also to denote the heating of springs afterfabrication in order to improve their properties. DISCUSSION—Except as required above, it is permissible for carbonsteel specifications to prescribe limits minimum or maximum, or both for each specified alloying element, subject to the following restrictionsfor the heat analysis limits in mass percent: a for wrought carbon steel products, the specified maximum limit isnot to exceed: 0.
It is preferred thatthe applicable specific process name be used. Use the preferred term heatanalysis. Use the preferred termproduct analysis. For conformance purposes, the mean value foriron, whether specified or calculated, is compared on an individualbasis to the mean values permitted by the specification for each of theother elements having a specified range or a specified maximum.
If anelement other than iron is not specified, but is listed as remainder orbalance, then, for conformance purposes the mean value for iron iscompared to the calculated value for that other element.
