201 Ibha yeNsimbi eNgatyiwayo
Inkcazo
Ukumelana nokubola
Inqanaba eliqhelekileyo le-Type 201's resistance resistance lithelekiseka ne-Type 301's.Kwiimeko ezininzi ezithambileyo, udidi lwe-201 kufuneka lusebenze ngokwanelisayo endaweni yohlobo lwe-301. Uhlobo lwe-201 lunokumelana nokulinganisa okuphantsi kunohlobo lwe-301. ukuya kutsho malunga ne-1500 °F (816 °C).
Ukwenziwa
Ngokufana noHlobo lwe-301, Uhlobo lwe-201 yensimbi engenasici inokwakheka ngokwenza ibhentshi, i-roll forming, kunye ne-brake bending.Kodwa ngenxa yamandla ayo amakhulu, inokuba ne-springback engaphezulu.Kwiimeko ezininzi, le mathiriyeli inokutsalwa ngokufanayo noHlobo lwama-301
ukuba amandla amaninzi asetyenziswa kwaye uxinzelelo lokubamba luphakanyisiwe, imisebenzi yokuzoba.
Ukuweldability
Ukudibanisa okusemgangathweni kunye neenkqubo zokumelana ne-welding zicingelwa ngokubanzi ukuba ziyakwazi ukujoyina iintsimbi ezingenasici kwiklasi ye-austenitic.Ngokuqinisekisa ukuba iifom ze-ferrite kwi-weld deposit, kufuneka kuthathelwe ingqalelo ekhethekileyo ukukhusela i-weld "i-hot cracking".Indawo echaphazelekayo ubushushu be-weld bunokuba buthathaka kwaye busengozini kwi-corrosion ye-intergranular kwezinye iimeko, njengakwamanye amabakala e-chrome-nickel austenitic steel stainless steel apho ikhabhoni ingalawulwa ukuya kwi-0.03% okanye ngaphantsi.Xa kuthelekiswa noHlobo lwe-304L yentsimbi engatyiwayo, eyona ngxubevange idumileyo kolu didi lungenaziphene, le ngxubevange icingelwa ukuba inokuweldability ngakumbi.Ezona nkcukacha zixhaphakileyo ze-AWS E/ER 308 kuxa kufuneka i-weld filler.Iinkcukacha ezithe kratya zinokufumaneka kuncwadi lwereferensi, oluyaziwa kakhulu ngodidi lwe-201 yentsimbi engenasici.
Unyango lobushushu
Udidi lwe-201 aluqiniswa ngonyango lobushushu.I-Annealing: I-Anneal kwi-1850 - 1950 °F (1010 - 1066 °C), emva koko kucinywe amanzi okanye kuphole ngokukhawuleza umoya.Iqondo lobushushu le-anneal kufuneka ligcinwe lisezantsi kangangoko, lihambelane neempawu ezinqwenelekayo, kuba udidi lwama-201 luthande ukwenza isikali ngaphezulu koHlobo lwama-301.
