Ukulawulwa kwe-Intergranular Corrosion ye-Austenitic Stainless Steel

Phakathi kokugqwala okuhlukahlukene kwensimbi engagqwali, ukubola okungaphakathi kwe-intergranular kubanga cishe i-10%. Izokwehlisa amandla okuhlanganisa phakathi kwamabele. Ngaphansi kwesenzo sokuxineka, kulula ukuqhekeka futhi uqhekeke ube yimpuphu, futhi kufihlwe kakhulu. Akubonakali ekubukekeni kwayo.

Ngasikhathi sinye, futhi kuyisizathu esiyinhloko sokuheha okunye ukugqwala. Ukugqwala kwangaphakathi kwensimbi engagqwali ye-austenitic kubangelwa kakhulu ukungabi bikho kwe-Cr endaweni yomngcele wokusanhlamvu, futhi u-C wenza kalula izinto ezihlanganiswa ne-Cr, okunciphisa okuqukethwe yi-Cr. Ngalesi sizathu, izindlela zokuvimbela ukugqwala kwangaphakathi yilezi:

　　 1. Ukwakhiwa kwamakhemikhali nokuhleleka

　　(1) C okuqukethwe

　　Okuqukethwe ngu-C kuyinsimbi okubaluleke kakhulu okuthinta ukugqwala kwangaphakathi kwensimbi engenasici i-austenitic. Ngakolunye uhlangothi, lawula ngokuqinile okuqukethwe kwe-C ukulawula okuqukethwe kwekhabhoni kwensimbi yensimbi kanye nenduku yokushisela engaphansi kuka-0.08%; ngakolunye uhlangothi, ukwengeza izinto zokuqinisa ezifana ne-Ti ne-Nb ezintweni zensimbi nezinto zokushisela zinokuhlangana okuqinile kweC. Ikhabhoni ihlanganiswe neCr ngaphambi kwayo, bese kwakhiwa inhlanganisela ezinzile.

　　(2) Inhlangano ye-Biphasic

　　 isakhiwo esimbaxambili sizothuthukisa kakhulu ikhono lokumelana nokugqwala kwangaphakathi. Ngakolunye uhlangothi, ukungeza izinto ezakha i-ferrite, njenge-chromium, i-silicon, i-aluminium, i-molybdenum, njll. ngakolunye uhlangothi, khetha okokushisela okuqukethe ama-generator amaningi we-ferrite.

　　2, inqubo Welding

　　(1) Izinga lokushisa lisebangeni lokushisa elingu-450 ~ 850 ℃, ikakhulukazi u-650 ℃ iyindawo yokushisa eyingozi kakhulu (eyaziwa nangokuthi indawo yokushisa yokuzwela) lapho ukugqwala kwangaphakathi kuvame ukwenzeka khona. Ngakho-ke, lapho kufakwa insimbi engagqwali, kungasetshenziswa ipuleti lethusi ngaphansi kwensimbi, noma amanzi angathelwa ngqo ngemuva kwensimbi ukuze ayipholise ngokushesha, kunciphise isikhathi sokuhlala kuleli banga lokushisa, okuyisilinganiso esisebenzayo sokwenza ngcono ukumelana ukugqwala ilunga. .

　　(2) Ukwanda kokushisela okokufaka kokushisa kuzosheshisa ukugqwala kwensimbi engagqwali ye-austenitic. Enqubeni yokushisela, okumanje okuncane, isivinini sokushisela okuphezulu, i-arc emfushane, i-multi-pass welding nezinye izindlela zingasetshenziswa ukunciphisa okokufaka kokushisa. Hlakulela okokufaka okushisayo okuphansi futhi usheshe udlule endaweni yokushisa esetshenzisiwe ukugwema ukugqwala okungaphakathi kwendawo ethintwe ukushisa.

　　3, ukwelashwa ngemuva kokushisela

　　 Ngemuva kokushisela, phinda uvuselele ukuhlangana okushiselwe kwensimbi engagqwali ye-austenitic kuye ku-1050 ~ 1100 ℃, ukwelashwa kabusha kwesixazululo, noma ukuphinda uvuselele ku-850 ~ 900 ℃, gcina i-2h, futhi wenze ukwelashwa kwe-homogenization ukuqeda indawo ephele i-chromium.

Sicela ugcine umthombo nekheli lale ndatshana ukuze uphinde uprintwe: Ukulawulwa kwe-Intergranular Corrosion ye-Austenitic Stainless Steel

UMinghe Inkampani yeDie Casting anikezelwe ekukhiqizeni nasekuhlinzekeni ikhwalithi nokusebenza okuphezulu Izingxenye Zokulingisa (izingxenye zensimbi zensimbi zokufa zisebenza ikakhulukazi zibandakanya I-Thin-Wall Die Casting,I-Hot Chamber Die Casting,Cold Chamber die Casting), Insizakalo Eyindilinga (Insiza Yokulingisa,ICnc Machining,Ukwenza Okubandayo, Surface Treatment) .Noma ikuphi ukusakazwa kwe-Aluminium die, i-magnesium noma i-Zamak / zinc die casting nezinye izidingo zokuphosa zamukelekile ukuxhumana nathi.

Ngaphansi kokulawulwa kwe-ISO9001 ne-TS 16949, Zonke izinqubo zenziwa ngamakhulu emishini esezingeni eliphakeme yokufa, imishini ye-5-axis, nezinye izikhungo, ezisukela kuma-blasters kuya kumishini yokuwasha ye-Ultra Sonic.Minghe akagcinanga ngemishini esezingeni eliphezulu kepha futhi unobuchwepheshe iqembu lonjiniyela abanolwazi, ama-opharetha nabahloli ukwenza ukwakheka kwekhasimende kugcwaliseke.

Umenzi wenkontileka yokufa kwabasikiwe. Amandla afaka izingxenye ezibandayo ze-aluminium die casting ezivela ku-0.15 lbs. kuye ku-6 lbs., Ukusetha ushintsho olusheshayo, nemishini. Izinsizakalo ezingezwe ngenani zifaka phakathi ukupholisha, ukudlidliza, ukuphazamisa, ukuqhumisa ngokudubula, ukupenda, ukuhlobisa, ukumboza, ukuhlangana nokusetshenziswa kwamathuluzi. Izinto zokusebenza ezisetshenzisiwe zifaka ama-alloys afana no-360, 380, 383, no-413.

I-Zinc die casting design usizo / izinsizakalo zobunjiniyela ezihambisanayo. Umenzi wangokwezifiso we-precision zinc die castings. Ukusakazwa okuncane, ukukhishwa kwengcindezi ephezulu, ukusikeka kwesikhunta esiningi, ukujikijelwa kwesikhunta okuvamile, ukufefa kwamayunithi kanye nokuzimela okuzimele kanye nokuvalwa okuvaliwe komgodi kungenziwa. Ama-Castings angenziwa ngobude nobubanzi obufinyelela ku-24 in. Ku +/- 0.0005 in. Ukubekezelelana.  

I-ISO 9001: Umkhiqizi oqinisekisiwe ka-2015 we-die cast magnesium, Amandla afaka i-high-pressure magnesium die casting up to 200 ton chamber hot & 3000 ton cold chamber, designing designing, polishing, molding, machining, powder & liquid paint, QA full with CMM amakhono , inhlangano, ukupakisha nokulethwa.
