Codsiga | Waraaqaha birta ah ee aan fiicnayn waxay khuseeyaan goobta dhismaha, warshadaha dhisaya maraakiibta, batroolka iyo warshadaha kiimikada, warshadaha dagaalka iyo korontada, warshadaynta cuntada iyo warshadaha caafimaadka, kululeeyaha kuleylka, mashiinada iyo beeraha hardware. xaashida birta ah ee aan fiicnayn waxaa loo samayn karaa iyadoo loo eegayo shuruudaha macmiilka.

410S waa la tirtiray, ama la jilicsanaa, si looga dhigo mid jajaban. Tan waxa lagu sameeyaa iyada oo lagu kululeeyo inta u dhaxaysa 1600 – 1650F (871 – 899°C), ka bacdi hawo si tartiib ah ugu qaboojiso heerkulka qolka si ay u yarayso culaysyada qabow ee shaqaynaysa. Walxaha, heerkulka xinjirowga waa in hoos loo dhigaa ilaa kala duwanaansho dhan 1200 – 1350°F (649 – 732°C). Si kastaba ha ahaatee, waa in aan waligood la kordhin 2000°F (1093°C) ama ka sareeya sababta oo ah qallafsanaanta, taas oo ah qayb ahaan ama gabi ahaanba luminta tubbada walxaha, lidka ku ah natiijada la rabo ee baabiinta 410S.
Iska caabbinta daxalka ugu badan ee deegaanka kiimikaad, dusha 410S waa in ay ahaataa mid xor ah dhammaan midabada kulaylka ama oksaydhka ee la sameeyay inta lagu gudajiro habka shaqada ee soo saarista ama kulul. Waa lagama maarmaan in dhammaan raadadka oksaydhka iyo kaarburization-ka dusha sare laga saaro iyadoo dhulka la saarayo ama la sifaynayo dhammaan sagxadaha. Ka dib, qaybo ka mid ah waxaa lagu dhex milmay 10% ilaa 20% nitric acid oo ay ku xigto biyo raacid. Tani waa si loo hubiyo ka saarista birta hadhaaga ah.
Tallaabadan ka dib, qaybaha 410S ee birta ah ayaa guud ahaan loo arkaa inay awood u leeyihiin inay alxanka ku maraan farsamooyinka fiyuuska caadiga ah iyo iska caabinta, inkasta oo fiiro gaar ah la siinayo si looga fogaado jabka alxanka inta lagu jiro abuuritaanka iyo in la yareeyo joojinta.
Farqiga ugu weyn ee u dhexeeya birta 410 iyo 410S waa in 410 ay tahay aasaas, ujeedo guud, birta birta ah ee martensitic taas oo la adkeyn karo halka 410S ay tahay wax ka beddelka Kaarboon hoose ee 410 birta aan fiicnayn, si fudud loo alxan karo laakiin leh hanti farsamo oo la dhimay. 410S birta aan lahayn si fudud ayaa loo samayn karaa iyadoo la sawirayo, la leexinayo, foorarsanaysa, iyo samaynta duubka
Codsiyada isticmaalaya 410S Chromium ferritic ahama birta ayaa si aad ah u kordhay sanadihii ugu dambeeyay warshadaha kiimikada iyo sidoo kale warshadaha saliida ama gaaska. Tijaabooyinka lagu ogaanayo heerkulka isbeddelka wejiga ayaa socda si loo go'aamiyo heerkulka beddelka alfa ilaa gamma ee daawaynta xaaladaha qaboojinta ee kala duwan. Natiijooyinka ayaa go'aamin doona sida 410S loogu isticmaali karo warshadahan.
