Ukwenziwa kanye Nokwelashwa Kokushisa
347/347H insimbi engagqwali 6.0 * 1.25mm ishubhu elihlanganisiwe/ishubhu le-capillary
Ukusebenziseka kalula
Insimbi engagqwali engu-347H iqine kancane kunezinga lensimbi yebanga lama-304.Kodwa-ke, ukuqina kwale nsimbi kungancishiswa ngokusetshenziswa kokuphakelayo okuhle njalo kanye nesivinini esincane.
Ukushisela
Ibanga lama-347H insimbi engagqwali ingashiselwa kusetshenziswa izindlela eziningi zokumelana nezindlela zokuhlanganisa.I-Oxyacetylene welding ayikhethwa kule nsimbi.
Kuyashisa Ukusebenza
Ukuqamba, ukucasula nezinye izinqubo zokusebenza ezishisayo zingenziwa ku-1149 kuya ku-1232 ° C (2100 kuya ku-2250 ° F).Insimbi yebanga elingu-347H kufanele icishwe amanzi futhi ifakwe emanzini ukuze ithole ubulukhuni obukhulu.
Ukusebenza Okubandayo
Ibanga 347H insimbi engagqwali ingagxivizwa kalula, ingambathi lutho, iphothe futhi idwetshwe njengoba iqinile futhi idonsa.
Anealing
I-Grade 347H insimbi engagqwali ingabanjwa ekushiseni okusukela ku-1010 kuya ku-1193°C (1850 kuya ku-2000°F) bese sicinywa ngamanzi.
Ukuqina
I-Grade 347H yensimbi engagqwali ayiphenduli ekwelashweni okushisa.Ukuqina namandla ensimbi kungandiswa ngokusebenza okubandayo.
