RA RATIONA TIONALE LE REGA REGARDIN RDING G DEFI DEFINITI NITION ON OF SOLU SOLUTION TION ANN ANNEALI EALING NG X1.1 X1. 1 It is gen general erally ly rec recogn ognized ized tha thatt aus austen tenitic itic stai stainle nless ss steels are solution annealed by heating to a temperature that dissolves (takes into solution) chromium carbides and quenching rapidly so that the chromium carbides will not precipitate in the gra grain in bou bounda ndarie ries, s, whi which ch cou could ld cau cause se sus suscep ceptib tibilit ility y to intergranular corrosion in a critically corrosive environment. Thus, solution annealing also can be accomplished for nonstabilized grades by taking advantage of hot rolling temperatures (which always exceed soluti solution on anneali annealing ng temper temperature ature requirements), maintaining hot rolling finishing temperatures well abo above ve min minimu imum m sol soluti ution on ann anneali ealing ng req requir uiremen ements, ts, and immediately immedia tely quen quenching ching integral with hot rolling. Stabili Stabilized zed grades (with columbium or titanium added) cannot be handled this way, since they would become destabilized due to colum- bium or titanium carbide solution, without subsequent reheating. X1.2 For Boiler Code applic applications ations involving involving temperatures temperatures at whi which ch opt optimu imum m res resista istance nce to cre creep ep is des desired ired,, the lar larger ger grain gr ain si size ze of ma mater teria iall so solu luti tion on an anne neale aled d by re rehe heati ating ng is generally desired. For that reason, a minimum grain size has been required of the H grades (created for optimum elevated temperature properties), and a mandatory grain size test and repo re port rt ha hass be been en ad adde ded d fo forr th thee no non– n–H H gr grad ades es so th that at th thee inform inf ormatio ation n is ava availab ilable le for tho those se des desirin iring g to recl reclass assify ify a non–H grade to H grade.
