Izindaba

Njengamanje, izinsimbi emakethe ikakhulukazi zihlanganisa insimbi engagqwali, carbon steel, ithusi, aluminium ingxubevange ezine izinhlobo zokusetshenziswa..

1. Insimbi yekhabhoni. Ukuze carbon steel impahla ekubunjweni carbon ukuhlukanisa phakathi low carbon steel, medium carbon steel, carbon steel high kanye ingxubevange yayo steel.

(1) insimbi ephansi ye-carbon C%≤ I-0.25% yaseChina ivame ukubizwa nge-A3 steel. Amanye amazwe nezifunda ngokuyisisekelo zibizwa ngokuthi 1008, 1015, 1018, 1022, njll. Isetshenziswa kakhulu kuzikulufu zebanga le-4.8 namantongomane ebanga lesi-4, izikulufo ezincane nezinye izimpahla ezingenawo amazinga wamandla. (Qaphela: I-Drill-tailizikulufungokuvamile asetshenziswa 1022 izinto zokusetshenziswa.)

(2) medium carbon steel 0.25% 0.60%. Okwamanje emakethe akukho ukusetshenziswa kwalesi sici.

(3) i-alloy steel: ku-carbon steel evamile yokwengeza izingxenye ze-alloy, enezela izici ezikhethekile ensimbi yokwakha: njenge-35, 40 chromium-molybdenum, SCM435, 10B38. Izikulufu zebanga elingu-12.9 ezisebenzisa i-SCM435 chromium-molybdenum alloy steel, izingxenye ezibalulekile ngu-C, Si, Mn, P, S, Cr, Mo.

2. Insimbi engagqwali. Ibanga lesici: 45, 50, 60, 70, 80. ikakhulukazi ihlukaniswe i-martensite (18% Cr, 8% Ni) ukumelana nokushisa okuhle, ukumelana nokugqwala okuhle. i-a1, a2, a4 martensite (13% Cr) ukumelana nokugqwala okubuthakathaka, amandla aphezulu, ukumelana nokugqokwa okuhle. c1, c2, c4430 insimbi engagqwali. U-18% we-Cr upsetting ungcono, ukumelana nokugqwala kunamandla kune-austenite. Izinto ezisetshenziswayo ezimakethe zamanje zihlukaniswe ikakhulukazi i-SUS302, SUS304, SUS316 ngebanga.

3. Ithusi. Izinto ezivamile zethusi, ingxubevange yethusi onsomi. Imakethe ivamise ukusetshenziswa i-H62, H65, H68 yethusi emikhiqizweni ejwayelekile.

4. I-aluminium alloy density iphansi, kodwa amandla okucindezela aphakeme kakhulu, aseduze noma ngisho nangaphezulu kwensimbi engavimbeli ukushisa, ipulasitiki enhle, ingenziwa ibe amaphrofayili e-aluminium ahlukahlukene, ane-conductivity enhle kagesi, ukudluliswa kokushisa nokugqwala. ukumelana, ukusetshenziswa kwezimboni kubanzi kakhulu, inani lensimbi yesibili kuphela.

1. Insimbi ye-alloy iphinde ibhekisele ku-chromium-molybdenum alloy steel, njenge-SCM435, njll.

Izinto ezisetshenziswayo ezivamile zama-fasteners

(A) i-carbon steel, i-alloy steel, isigaba sensimbi esikhethekile

1, amabhawodi, izikulufu, izikulufu 3.6 grade, 4.6 grade, 4.8 grade, 5.6 grade, 5.8 grade, 6.8 grade ukukhetha jikelele carbon steel, akukho inqubo ukushisa ukushisa; Ibanga le-8.8, izinga le-9.8 ukukhetha okujwayelekile kwensimbi ephansi ye-carbon Environmental alloy noma i-medium carbon steel, ecishiwe futhi ethambile; Ibanga le-10.9 ukukhetha okujwayelekile kwensimbi ephansi nephakathi ye-carbon alloy noma i-alloy steel, ecishiwe futhi ethambile; I-12.9 yezinga lokukhetha okujwayelekile kwensimbi ye-alloy, ecishiwe futhi eqinile. Ukuthukuthela.

2, amantongomane 4, 5, 6 ukukhetha jikelele carbon steel, kodwa futhi kuyatholakala lula ukusika steel yokukhiqiza, akukho inqubo ukushisa ukushisa; I-8, 9, ukukhetha okujwayelekile kwensimbi ye-carbon ephakathi, ecishiwe futhi eqinile; 10, 12 ukuthuthukisa izakhiwo zomzimba, uma kunesidingo, kungandisa ukwakheka kwe-alloy, kucinywe futhi kuthukuthele.

3, Izikulufo zokubopha ezingu-14H ngokuvamile zikhetha insimbi ye-carbon, ayikho inqubo yokwelapha ukushisa; I-22H, i-33H ngokuvamile ikhetha insimbi ye-carbon, ecinyiwe futhi epholile; I-45H ngokuvamile ikhetha insimbi ye-alloy, ecishiwe futhi eqinile.

4, I-Flat pad HV140 ngokuvamile ikhetha insimbi ye-carbon ephansi; I-HV300 ngokuvamile ikhetha insimbi ye-carbon steel, kufanele inqubo yokushisa ukushisa.

5,Izikhonkwane ezizithephayo/izinzipho zokuzibhoboza ngokuvamile zikhethwa kunsimbi yekhabhoni emaphakathi njenge-SWRCH22A, ungqimba olungaphezulu kufanele lufakwe i-carburized.

(B) insimbi engagqwali izinto zokusetshenziswa

Izinto zensimbi engagqwali:insimbi engagqwali ibhawudi impahla ine-Q215 ne-Q235 kanye ne-25 kanye ne-45 kanye nezinto zensimbi, intambo phakathi kwebhawodi kwesinye isikhathi izodinga ukuhlangana okubalulekile, bese ungasebenzisa i-15Cr ne-20Cr nokunye kanye no-30CrMri le ingxubevange yensimbi, ukuze izakhiwo zemishini Ibhawodi izothuthukiswa. Iqukethe 9 ukwakheka kwamakhemikhali, ngokulandelana ni, cu, c, s, si, p, mn, cr. izinto zensimbi engagqwali: 201, 304, 316, 304L, 316L, 2205, 2507, 310S, 321, 904L, 667 njalonjalo.

Izinhlobo zesingeniso: 302HQ lapho umthombo oyinhloko uthinta izinzipho; I-SUS304, i-A2 ingenye igama layo, into eyinhloko yokukhiqiza amabhawodi ensimbi engagqwali, izikulufu zensimbi engagqwali, amawasha ensimbi engagqwali namantongomane ensimbi engagqwali, inani lezinga lamandla lincane ohlangothini olungaphezulu; I-SUS316 ne-SUS316L, eyaziwa nangokuthi i-A4, egqwala kakhulu kune-A2, amabhawodi ensimbi engagqwali, izikulufu zensimbi engagqwali, amawasha ensimbi engagqwali, ukukhiqizwa kwamantongomane ensimbi engagqwali, leli nani lebanga lamandla kanye ne-A2 kungafana, kodwa futhi kungaba inamandla kancane kune-A2.

I-Nanning Aozhan Hardware Fastener Co., Ltd. ikhiqiza futhi icubungule amabhawodi ensimbi engagqwali, amantongomane ensimbi engagqwali, amawasha, izipikili ezizishayayo, izinzipho zokubhoboza, njll. Iminyaka eyi-10 igxila ekwenzeni amabhawodi nezikulufu ngendlela oyifisayo.
