Njengoba sonke sazi, izinto zokwakha ama-fasteners ezinsimbi ezingenasici zihlukaniswa zibe yinsimbi yensimbi engenacala, insimbi engenasici engenasici kanye nensimbi engenacala.
Amamaki e-BOLTS yensimbi engagqwali ahlukaniswe yaba ngu-45, 50, 60, 70, no-80. Izinto zokwakha zihlukaniswe kakhulu i-Auucenite A1, A2, A4, A4, A4, I-Martite C1, C2, kanye no-C4. Indlela yayo yokukhuluma ifana ne-A2-70, ngaphambi nangemva kwalokho "-" ngokulandelana ikhombisa izinto ezibonakalayo kanye neleveli yamandla.
1.Feferric insimbi engagqwali
(15% -18% Chromium) - Insimbi Engagqwali Engagqwali inamandla ashubile angama-65,000 - 87,000 psi. Yize kusamelana nokugqwala, akunconywa ukuthi kusetshenziswe ezindaweni lapho kuvela khona ukugqwala, futhi kufanelekile ngezikulufo zensimbi ezingagqwali ngokumelana nokushisa okuphezulu okuphezulu nokuphikiswa ukushisa, kanye nezidingo zamandla ajwayelekile. Lokhu kusetshenziswa akunakubalwa ukushisa. Ngenxa yenqubo yokubumba, kungubutheni futhi akufanelekile ukuthengisa. Amabanga we-Ferritic afaka: 430 no-430f.
Insimbi engu-2.Martsitic engenacala
(12% -18% Chromium) - Insimbi Engagqwali Ebunjiwe ibhekwa njengensimbi kazibuthe. Kungaba ukushisa okuphathwe ukukhulisa ubulukhuni bakhona futhi akunconywa ukufudumala. Ama-steren angenasici alolu hlobo afaka: 410, 416, 420, no-431. Banamandla ashubile phakathi kuka-180,000 no-250,000 PSI.
Uhlobo 410 bese uthayipha u-416 ungaqiniswa ukwelashwa kokushisa, ngobulukhuni be-35-45hrc kanye nemishini emihle. Zingamelana nezinsimbi ezingavikeleki futhi zivimbela izikulufa ezingavikeleki kwezinjongo ezijwayelekile. Uhlobo lwe-416 lunokuqukethwe okuphezulu okuphezulu kwe-sulfur futhi kuyinsimbi elula engasikiwe. Thayipha u-420, ngokuqukethwe kwesibabule ngo-R0.15%, kuthuthukise izakhiwo zemishini futhi kungaqiniswa ukwelashwa kokushisa. Inani eliphakeme kakhulu lobulukhuni lingu-53-58HRC. Isetshenziselwa izikulufa zensimbi ezingagqwali ezidinga amandla aphezulu.
Insimbi ye-3.auuuTenitic engenacala
(15% -20% Chromium, 5% -19% nickel) - Ama-autenitic ama-stainless amabala anokumelana okuphezulu kakhulu kwezinhlobo ezintathu. Lesi sigaba sensimbi engenasici sifaka amamaki alandelayo: 302, 303, 304, 304l, 316, 321, 347, 321, 347, 328. Banamandla ashubile phakathi kuka-80,000 - 150,000 Psi. Noma ngabe kungukumelana nokukhulisa, noma izakhiwo zalo zemishini ziyafana.
Thayipha i-302 isetshenziselwa izikulufo ezibhaliwe kanye nama-bolts wokuzishaya.
Thayipha u-303 ukuze uthuthukise ukusebenza kokusika, inani elincane lesibabule selingezwa ukuthayipha kwensimbi engama-303 yensimbi engenacala, esetshenziselwa ukucubungula amantongomane avela ku-bar stock.
Uhlobo lwe-304 lufanelekile ukucubungula izikulufa zensimbi ezingenasici ngenqubo eshisayo yesihloko, njengama-bolts amade nesikhathi eside kanye nama-bolts amakhulu abubanzi, angeqa umkhawulo wenqubo yamaphuzu ebandayo.
Uhlobo lwe-305 lufanelekile ukucubungula izikulufa zensimbi ezingagqwali ngenqubo yesihloko esibandayo, njengama-nati ebandayo asungulwa nama-hexagonal bolts.
Izinhlobo ezingama-316 nezincwadi ezingama-317, zombili ziqukethe i-alloying element mo, ngakho-ke amandla abo okushisa aphezulu kanye nokuphikiswa ukugcusana kuphakeme kune-18-8 insimbi engagqwali.
Thayipha u-321 bese uthayipha 347, uhlobo 321 equkethe i-TI, into eguqukayo, bese uthayipha 347 iqukethe i-NB, ethuthukisa ukumelana nokugqwala kwezinto ezibonakalayo. Ilungele izingxenye ezijwayelekile zensimbi engenasici ezingafakwanga ngemuva kokushiswa noma zisenkonzweni ngo-420-1013 ° C.
