Muchimiro chezvigadzirwa zvepurasitiki, zvinhu zvema screws zvine chekuita nezvinhu zvinodiwa nechigadzirwa, senge saizi yesimba, uye simbi isina tsvina inoshandiswa kunze kwepurasitiki, uye kabhoni simbi screws inoshandiswa pane. mukati.Nzira yekusarudza simbi isina tsvina?
1: Mukutaura kwe layman, kabhoni simbi screws haina simbi ine alloy zvinhu zvakawedzerwa nemaune, uye Stainless simbi screws isimbi ine yakakwira alloy content yakawedzerwa kudzivirira ngura.
2: Stainless simbi screws inodhura zvakanyanya kupfuura kabhoni simbi screws.
3: Aya marudzi maviri emasiruu akasiyana, saka haakwanise kuenzaniswa.Carbon steel screws anowanzo kusimba kupfuura simbi isina tsvina, asi ari nyore kuita ngura.
Zvishandiso zvesimbi isina tsvina screws uye kabhoni simbi screws zvakasiyana, uye nharaunda yekushandiswa yakasiyanawo.Simbi yekabhoni haina kusimba mukuora, uye mabhaudhi anozoita ngura kusvika afa mushure menguva refu.Stainless simbi screws zviri nani.
Stainless simbi sikuruu
Zvishandiso zvesimbi isina tsvina screws uye kabhoni simbi screws zvakasiyana, uye nharaunda dzavanoshandiswa nadzo dzakasiyana.
Kudzivirirwa kwekuora kwekabhoni simbi kwakashata, uye mabhaudhi anozoita ngura kusvika afa mushure menguva refu.Stainless simbi mabhaudhi ari nani.Heano zvimwe zvekushandisa zveStainless simbi mabhaudhi:
Material classification of Stainless steel screws
Inoshandiswa pakugadzirwa kwesimbi isina tsvina screws.Zvishandiso zvestainless simbi screws zvakakamurwa kuita austenitic Stainless simbi, ferritic Stainless simbi, martensitic Stainless simbi uye kunaya kwemvura kuomesa simbi isina tsvina.Kusarudzwa kwesimbi isina tsvina screws zvakare mune musimboti.Kubva pane chii, rega iwe usarudze Stainless simbi screws yaunoda.
Mushure mekutarisa kwakadzama uye kwakadzama kweaya maficha mashanu, giredhi, akasiyana, mataurirwo uye chiyero chemidziyo yestainless simbi screws inozopedzisira yatemwa.
Ferritic simbi isina tsvina
Type 430 yakajairwa chromium simbi ine zvirinani corrosion resistance uye kupisa kupisa kupfuura Type 410, uye ine magineti, asi haigone kusimbiswa nekupisa kurapwa.Inokodzera simbi isina tsvina ine zvishoma yakakwira corrosion resistance uye kupisa kupisa uye zvakajairika simba zvinodiwa.screw.
Martensitic simbi isina tsvina
Type 410 uye Type 416 inogona kusimbiswa nekupisa kurapwa, nekuoma kwe35-45HRC uye yakanaka machinability.Iwo anodzivirira kupisa uye anodzivirira corrosion-resistain stainless simbi screws nokuda kwezvinangwa zvakawanda.Type 416 ine sarufa yakakwira zvishoma uye iri nyore kucheka simbi isina tsvina.
Type 420, sulfur content ?R0.15%, yakagadziridzwa michina zvivakwa, inogona kusimbiswa nekupisa kurapwa, yakanyanya kuomarara kukosha 53 ~ 58HRC, inoshandiswa kune Stainless simbi screws inoda simba rakakwirira.
Stainless simbi sikuruu
Kunaya kwakaoma Stainless Simbi
17-4PH, PH15-7Mo, vanogona kuwana simba rakakwirira kudarika rakajairika 18-8 simbi isina tsvina, saka ivo vanoshandiswa kune yakakwirira-simba, corrosion-resistain stainless simbi screws.
A-286, isiri-standard Stainless simbi, ine yakakwira corrosion resistance pane inowanzo shandiswa 18-8 type Stainless steel, pamwe neakanaka ma mechanical properties patembiricha dzakakwirira.Inoshandiswa seyepamusoro-simba, inodzivirira kupisa uye inodzivirira simbi isina tsvina screws, inogona kushandiswa kusvika 650-700 ° C.
Stainless simbi sikuruu
Austenitic simbi isina tsvina
Magiredhi anowanzo shandiswa 302, 303, 304, uye 305, ayo ari magiredhi mana einonzi "18-8" austenitic stainless steel.Ingave iri corrosion resistance, kana kuti ma mechanical properties akafanana.Nzvimbo yekutanga yekusarudza ndiyo nzira yekugadzira yesimbi isina tsvina screws, uye nzira yacho inoenderana nehukuru uye chimiro chestainless simbi screws, uye zvakare zvinoenderana nehuwandu hwekugadzira.
Type 302 inoshandiswa kune akagadzirwa screws uye ega-tapping mabhaudhi.
Type 303 Kuti uvandudze kuita kwekucheka, chidimbu chesarufa chinowedzerwa kune Type 303 simbi isina tsvina, iyo inoshandiswa kugadzira nzungu kubva kubhawa stock.
Type 304 inokodzera kugadzirisa simbi isina simbi screws neinopisa musoro maitiro, senge mabhaudhi akareba uye mabhoti mahombe edhayamita, anogona kudarika chiyero chekutonhora kwemusoro.
Type 305 inokodzera kugadzirisa simbi isina simbi screws nekutonhora musoro maitiro, senge inotonhora yakagadzirwa nzungu uye hexagonal mabhaudhi.
Type 309 neType 310 dzine yakakwira Cr neNi content pane Type 18-8 stainless steel, uye inokodzera mastainless simbi screws anoshanda pakupisa kwakanyanya.
316 uye 317 mhando, iwo ese ane alloying element Mo, saka iwo tembiricha yakanyanya simba uye corrosion resistance yakakwira kupfuura 18-8 stainless steel.
Type 321 uye Type 347, Type 321 ine Ti, yakagadzikana alloying chinhu, uye Type 347 ine Nb, inovandudza intergranular corrosion kuramba kwezvinhu.Yakakodzera simbi isina simbi yakajairwa zvikamu zvisina kuvharwa mushure mekunama kana zviri kushanda pa420-1013 °C.
