201 Birta Birta Ah
Sharaxaada
Iska caabin daxalka
Heerka guud ee iska caabbinta daxalka Nooca 201 waxa uu la mid yahay Nooca 301.Inta badan xaaladaha khafiifka ah, Nooca 201 waa inuu u shaqeeyaa si ku qanacsan booska 301. Nooca 201 wuxuu leeyahay iska caabin miisaan hoose marka loo eego Nooca 301. Nooca 201 wuxuu ku saabsan yahay 50 ° F (28 ° C) ka yar adkaysi u yeelashada qolof burburinta nooca 301 ilaa 1500 °F (816 °C).
Farsamaynta
Si la mid ah Nooca 301, Nooca 201 ee birta aan lahayn waxaa lagu samayn karaa samaynta kaydka, duubista samaynta, iyo foorarsiga biriiga.Laakiin sababtoo ah xooggeeda weyn, waxaa laga yaabaa inay dib u soo noqoto.Inta badan, walxahan waxa loo sawiri karaa si la mid ah Nooca 301
haddii awood dheeraad ah la isticmaalo iyo cadaadiska hoos u dhigista oo kor loo qaado, sawirida waxqabadyada.
Weldability
Fiyuuska caadiga ah iyo hababka alxanka iska caabinta ayaa si weyn loo maleynayaa inay awood u leeyihiin inay ku biiraan birta aan fiicnayn ee fasalka austenitic.Iyadoo la hubinayo in ferrite ay ku jirto deebaajiga alxanka, waa in taxadar gaar ah la sameeyaa si looga hortago alxanka "dillaaca kulul".Aagga kulaylka alxanka saameeyaa waxa laga yaabaa inay noqoto mid xasaasi ah oo u nugul daxalka intergranular xaaladaha qaarkood, si la mid ah darajooyinka kale ee chrome-nickel austenitic ahama ee aan kaarboonka aan la koontaroolin 0.03% ama ka yar.Marka la barbar dhigo Nooca 304L steel steel, kaas oo ah daawaha ugu caansan fasalkan aan nadiifka ahayn, daawayntan gaarka ah ayaa sida caadiga ah loo maleynayaa inay leedahay alxanka xun.Tilmaamaha ugu badan ee AWS E/ER 308 waa marka buuxinta alxanka loo baahan yahay.Faahfaahin dheeraad ah ayaa laga heli karaa suugaanta tixraaca, taas oo si fiican loogu yaqaan Nooca 201 Steel steel.
Daaweynta kulaylka
Nooca 201 laguma adkeeyo daawaynta kulaylka.Annealing: Anneal at 1850 - 1950 °F (1010 - 1066 °C), ka dibna biyaha demi ama si degdeg ah hawo qabow.Heerkulka xuubka waa in loo hayaa sida ugu hooseeya ee suurtogalka ah, si waafaqsan sifooyinka la rabo, sababtoo ah Nooca 201 wuxuu u muuqdaa inuu ka miisaan ka badan yahay Nooca 301
