Ikhwalithi ephezulu ye-Wuxi mill ukuthekelisa i-SUS 304 ipuleti lensimbi engagqwali

Incazelo emfushane:

Uyini umehluko phakathi kwensimbi engagqwali engu-304 no-316:

304 ipuleti lensimbi engagqwali iyamelana nokugqwala nge-sulfuric acid, i-phosphoric acid, i-formic acid, i-urea, njll., futhi ilungele amanzi ajwayelekile, igesi yokulawula, iwayini, ubisi, uketshezi lokuhlanza i-CIP nezinye izikhathi ezinokubola okuphansi noma ukungathintani nezinto zokwakha. 316L steel grade unezele molybdenum element ngesisekelo 304, ezingasetshenziswa kakhulu ngcono ukumelana yayo ukugqwala intergranular kanye oxide ukucindezeleka ukugqwala futhi ukunciphisa ukuthambekela of ngokuhlaziya ashisayo ngesikhathi Welding. It Ubuye ukumelana okuhle chloride ukugqwala. Imvamisa isetshenziswa emanzini amsulwa, amanzi acolisisiwe, imithi, amasoso, uviniga nezinye izikhathi ezinezidingo eziphakeme zenhlanzeko kanye nezakhiwo ezinamandla zokugqwala imidiya. Intengo ka-316L icishe iphindwe kabili kunaleyo engama-304. Izakhiwo ezinomshini ezingama-304 zingcono kunezika-316L. Ngenxa yokumelana nokugqwala nokumelana nokushisa kwe-304 kanye ne-316, zisetshenziswa kakhulu njengensimbi engenamakhaza emelana nokushisa. Amandla nobulukhuni buka-304 no-316 kuyafana. Umehluko phakathi kwalokhu ukuthi ukumelana nokugqwala okungu-316 kungcono kakhulu kunalokho kuka-304. Iphuzu elibaluleke kakhulu ukuthi insimbi ye-molybdenum yengezwe ku-316, okuthuthukisa ukumelana nokushisa.
