201 Chitsulo chosapanga dzimbiri
Kufotokozera
Kukana dzimbiri
Mulingo wambiri wa kukana kwa dzimbiri kwa Type 201 ndi wofanana ndi wa Type 301's.Nthawi zambiri zofatsa, Mtundu wa 201 uyenera kugwira ntchito moyenera m'malo mwa Mtundu wa 301. Mtundu wa 201 uli ndi kukana kwapang'onopang'ono kusiyana ndi mtundu wa 301. Mtundu wa 201 uli pafupi ndi 50 °F (28 °C) wosagonjetsedwa ndi makulitsidwe owononga kusiyana ndi mtundu wa 301. mpaka 1500 °F (816 °C).
Kupanga
Zofanana ndi Type 301, Type 201 zitsulo zosapanga dzimbiri zimatha kupangidwa kudzera pakupanga benchi, kupanga mipukutu, ndi kupindika mabuleki.Koma chifukwa cha mphamvu zake zazikulu, zimatha kukhala ndi zotumphukira zambiri.Nthawi zambiri, nkhaniyi imatha kukokedwa mofanana ndi Type 301
ngati mphamvu yowonjezereka ikugwiritsidwa ntchito ndipo kupanikizika kwapansi kumakwezedwa, kujambula ntchito.
Weldability
Njira zosakanikirana ndi zowotcherera zimaganiziridwa kuti zitha kujowina zitsulo zosapanga dzimbiri m'gulu la austenitic.Poonetsetsa kuti mawonekedwe a ferrite mu weld deposit, chisamaliro chapadera chiyenera kutengedwa kuti tipewe "kuphulika kotentha".Malo okhudzidwa ndi kutentha kwa weld amatha kukhala ovuta komanso osatetezeka ku dzimbiri zamkati nthawi zina, monga momwe zimakhalira ndi chrome-nickel austenitic zitsulo zosapanga dzimbiri pomwe mpweya suwongoleredwa mpaka 0.03% kapena kuchepera.Poyerekeza ndi Mtundu wa 304L Stainless Steel, womwe ndi aloyi wotchuka kwambiri m'kalasi yosapanga dzimbiri, aloyiyi nthawi zambiri imaganiziridwa kuti imakhala yowotcherera kwambiri.Kufotokozera pafupipafupi kwa AWS E/ER 308 ndipamene chowotchera chimafunikira.Zambiri zitha kupezeka m'mabuku ofotokozera, omwe amadziwika bwino ndi Type 201 Stainless Steel.
Kutentha mankhwala
Mtundu wa 201 suumitsidwa ndi chithandizo cha kutentha.Annealing: Anneal pa 1850 - 1950 ° F (1010 - 1066 ° C), kenako madzi amathimitsa kapena mpweya wozizira kwambiri.Kutentha kwa annealing kuyenera kukhala kotsika momwe kungathekere, kogwirizana ndi zomwe mukufuna, chifukwa mtundu wa 201 umakonda kukula kuposa Type 301.
