201 Ibha Yensimbi Engagqwali
Incazelo
Ukumelana nokugqwala
Izinga elijwayelekile lokumelana nokugqwala kohlobo lwama-201 liqhathaniswa nohlobo lwama-301.Ezimweni eziningi ezithambile, Uhlobo 201 kufanele lusebenze ngendlela egculisayo esikhundleni sohlobo 301. Uhlobo 201 lunokumelana nesikali okuphansi kunohlobo 301. Uhlobo 201 lucishe lufane no-50 °F (28 °C) lumelane kancane nesikali esilimazayo kunoHlobo 301. kuze kufike ku-1500 °F (816 °C).
Ukwenziwa
Ngokufana Nohlobo 301, Uhlobo 201 lwensimbi engagqwali lungakhiwa ngokwakhiwa kwebhentshi, ukwakhiwa kwamaroli, kanye nokugoba amabhuleki.Kodwa ngenxa yamandla ayo amakhulu, ingase ibe ne-springback eyengeziwe.Ezimweni eziningi, le nto ingadonswa ngokufanayo ku-Type 301
uma amandla engeziwe esetshenziswa futhi ingcindezi yokubamba iphakanyisiwe, imisebenzi yokudweba.
Ukushisela
Izinqubo ezijwayelekile zokuhlanganisa kanye nezinqubo zokushisela kucatshangwa kabanzi ukuthi zingakwazi ukuhlanganisa izinsimbi ezingenasici ekilasini le-austenitic.Ngokuqinisekisa ukuthi amafomu e-ferrite ku-weld deposit, ukunakekelwa okukhethekile kufanele kuthathwe ukuvimbela i-weld "ukuqhekeka okushisayo".Indawo ethintekile ekushiseleni ingase ibe bucayi futhi ibe sengozini yokugqwala okuphakathi kwezinye izimo, njengakwamanye amamaki ensimbi engagqwali ye-chrome-nickel austenitic lapho ikhabhoni ingalawulwa ibe ngu-0.03% noma ngaphansi.Uma kuqhathaniswa noHlobo lwe-304L Stainless Steel, okuyingxubevange edume kakhulu kuleli klasi elingagqwali, le ngxubevange ethile ngokuvamile kucatshangwa ukuthi inokushisela okubi kakhulu.Ukucaciswa okuvama kakhulu kwe-AWS E/ER 308 yilapho kudingeka isigcwalisi se-weld.Imininingwane eyengeziwe ingatholakala ezincwadini eziyisethenjwa, ezaziwa kakhulu ngo-Type 201 Stainless Steel.
Ukwelashwa kokushisa
Uhlobo 201 aluqiniseki ngokwelashwa okushisa.I-Annealing: I-Anneal ngo-1850 - 1950 °F (1010 - 1066 °C), bese ivala amanzi noma iphole ngokushesha.Izinga lokushisa le-anneal kufanele ligcinwe liphansi ngangokunokwenzeka, lihambisana nezakhiwo ezifunwayo, ngoba Uhlobo 201 luvame ukukala ngaphezu koHlobo 301.
