DESCRIPTION
I-304H iyinsimbi engagqwali ye-austenitic, ene-chromium engu-18-19% kanye ne-nickel engu-8-11% enezinga eliphezulu le-carbon engu-0.08%. Amapayipi ensimbi engagqwali angu-304H angamapayipi ahlukahlukene futhi asetshenziswa kabanzi emndenini wensimbi engagqwali. Zibonisa ukumelana nokugqwala okuhle kakhulu, amandla amakhulu, ukukhululeka okuphezulu kokwenziwa, kanye nokwakheka okuvelele. Ngakho-ke, zisetshenziswa ezinhlobonhlobo zezicelo zasekhaya nezentengiso. Insimbi engagqwali engu-304H inokuqukethwe kwekhabhoni elawulwayo okungu-0.04 kuya ku-0.10. Lokhu kunikeza amandla athuthukisiwe okushisa okuphezulu, nangaphezulu kuka-800o F. Uma kuqhathaniswa no-304L, amapayipi ensimbi engagqwali angu-304H anamandla amakhulu esikhathi esifushane nawesikhathi eside. Futhi, amelana kakhulu nokuzwela kuno-304L.
304H IZIMPAPHA ZAMApayipi Ensimbi ENGGAMA
Okubalulwe ngezansi yizici ezibalulekile zamapayipi ensimbi engagqwali angu-304H ahlinzekwa yi-Arch City Steel & Alloy:
Ukumelana Nokushisa:
-
Ifanele ukusetshenziswa kwezinga lokushisa eliphezulu, njengoba inikeza amandla aphezulu emazingeni okushisa angaphezu kuka-500° C nokufika ku-800° C.
-
IBanga 304H linikeza ukumelana okuhle kwe-oxidation kusevisi yesikhashana ukuya ku-870° C futhi enkonzweni eqhubekayo kuya ku-920° C.
-
Iyazwela ebangeni lokushisa elingu-425-860° C; ngakho-ke akunconywa uma kudingeka ukumelana nokugqwala okumanzi.
Ukumelana Nokugqwala:
-
Ukumelana kahle nokugqwala ezindaweni ezine-oxidizing, kanye nama-asidi e-organic anolaka ngokumaphakathi ngenxa yokuba khona kwe-chromium ne-nickel ngokulandelanayo.
-
Isebenza ngokufanayo ezindaweni ezigqwalile
-
Ingase ibonise izinga eliphansi lokugqwala uma liqhathaniswa nebanga le-carbon ephezulu elingu-304.
Ukushisela:
-
Ishiselwe kalula yizinqubo eziningi ezijwayelekile.
-
Kungase kudingeke ukuba anneal ngemva kokushisela
-
I-Annealing isiza ekubuyiseleni ukumelana nokugqwala okulahleke ngokuzwela.
Iyacubungula:
- Amazinga okushisa okusebenza anconyiwe angu-1652-2102° F
- Amapayipi noma amashubhu kufanele afakwe ku-1900 ° F
- Impahla kufanele icinywe ngamanzi noma ipholiswe ngokushesha
- Ibanga le-304H liyi-ductile futhi lakha kalula
- Ukwakheka okubandayo kusiza ukukhulisa amandla nobulukhuni bebanga lama-304H
- Ukwakheka okubandayo kungenza ingxubevange ibe yizibuthe kancane
Ukukwazi komshini:
-
Imiphumela ehamba phambili itholakala ngesivinini esiphansi, ukugcotshwa okuhle, ukuphakelwa okusindayo, namathuluzi abukhali
-
Kuncike ekusebenzeni ukuqina kanye nokuphulwa kwe-chip ngesikhathi sokuguqulwa.
Izicelo zeBanga 304H Amapayipi Ensimbi Engagqwali
Ezinye izibonelo zezinhlelo ezisetshenziswa kakhulu ibanga 304H zihlanganisa:
- Izihlungi ze-Petroleum
- Ama-boilers
- Amapayipi
- Izishintshi zokushisa
- Ama-Condensers
- I-steam iyaphela
- Ukupholisa imibhoshongo
- Izitshalo ezikhiqiza ugesi
- Isetshenziswa ngezikhathi ezithile kumanyolo kanye nezitshalo zamakhemikhali
