Icyiciro cya 8.8, 10.9 & 12.9 Bolts na Screw: Basabwe ibikoresho byibanze kubikoresho byimbaraga zikomeye
2026-06-23
Guhitamo ibikoresho biboneye nibyo shingiro ryo gutanga umusaruro wizewe-imbaraga zikomeye, imigozi, hex, na sitidiyo. ISO 898-1 isobanura ibyiciro byumutungo wububiko bwa metero - cyane cyane Icyiciro cya 8.8, Icyiciro 10.9, nicyiciro cya 12.9. Buri cyiciro kigaragaza imbaraga ntoya, imbaraga zitanga umusaruro, hamwe nubukomezi gusa intego yatoranijwe nicyuma, ifatanije nubuvuzi bukwiye, ishobora kugeraho buri gihe.
Icyiciro 8.8 Bolts & Imiyoboro - Hagati-Imbaraga Zisumbuye
Icyiciro cya 8.8 gifata (imbaraga zingana zingana 800 MPa, igipimo cy'umusaruro 0,80) nizo zikoreshwa cyane muri rusange-intego rusange yubatswe kwisi yose. Bitwikiriye ibishashara, imigozi ya hex, ibinyabiziga bitwara abagenzi, ibyuma bya sitidiyo, hamwe n’imigozi yuzuye yuzuye yo kubaka ibyuma, guteranya amamodoka, hamwe n’imashini rusange.
Ibikoresho Byasabwe
- 35 # Icyuma giciriritse-Carbone - Bikwiranye na diameter ntoya (≤ M16). Ikiguzi-cyiza, gukomera bihagije kurwego rwa 8.8 nyuma yo kuzimya-n'ubushyuhe (Q&T).
- 45 # Icyuma giciriritse-Carbone - Guhitamo gukunzwe cyane kuri Grade 8.8 hex na sitidiyo. Imashini nziza, imiterere yubukanishi nyuma ya Q&T.
- 40Cr Amashanyarazi - Bikunzwe kuri diameter nini (M20 +). Kwiyongera kwa Chromium bitezimbere gukomera hamwe no guhuza ibice bitandukanye.
Gushyushya Ubushyuhe & Porogaramu
Kuzimya & Ubushyuhe (Q&T). Ubusanzwe ubukana buringaniye: 22-32 HRC. Porogaramu: guhuza ibyuma byubatswe, chassis yimodoka, imashini rusange, guhuza impande, guhuza ibiti-byuma.
Icyiciro 10.9 Bolts & Imiyoboro - Imbaraga Zirenze
Icyiciro cya 10.9 bolts na screw bitanga byibuze imbaraga zingana zingana na 1040 MPa. Zisobanuwe ahantu hose hashobora gukenerwa, guhuza imbaraga-gukenera imbaraga - kuva kuri moteri yimodoka kugeza kubikoresho biremereye cyane. Imiterere y'ibicuruzwa bisanzwe birimo sock head cap screw, flanged hex bolts, hamwe na sitidiyo ikomeye.
Ibikoresho Byasabwe
- 40Cr Amashanyarazi - Ifarashi isanzwe yo mu cyiciro cya 10.9. Birazwi cyane gukomera, kuboneka cyane, kandi byemejwe na ISO 898-1 ibisabwa.
- 35CrMo Amashanyarazi - Chromium-molybdenum ibyuma hamwe no gukomera gukomeye hamwe no kurwanya umunaniro. Bisanzwe kuri bolts na screw munsi yingufu zipakurura.
- 42CrMo Amashanyarazi - Ibirimo karubone birenze 35CrMo; itanga imbaraga nziza-gukomera kuringaniza ya diameter nini ya Grade 10.9 hex.
- SCM435 (JIS) - Inganda zUbuyapani zihwanye na 35CrMo. Byakoreshejwe cyane muri Aziya-Pasifika byihuta byo gutanga; guhoraho.
Gushyushya Ubushyuhe & Porogaramu
Kuzimya & Ubushyuhe (Q&T). Ubusanzwe ubukana buringaniye: 32–39 HRC. Porogaramu: gushiraho moteri ya moteri, guhagarika no gufata ibyuma bifata amashanyarazi, umunara wa turbine umunara, guhuza imiterere iremereye.
Icyiciro cya 12.9 Bolts & Screws - Ultra-High Imbaraga
Icyiciro cya 12.9 nicyiciro cyumutungo usanzwe murwego rwo hejuru (metero ntoya 1,220 MPa). Imbaraga zidasanzwe zisaba ibyuma bisobanutse neza hamwe na chimie igenzurwa cyane. Ibi bifunga - cyane cyane sock head cap screws hamwe na bolts yihariye yinganda - bikoreshwa ahantu hose umutekano wumutekano nubuzima bwumunaniro bidashoboka.
Ibikoresho Byasabwe
- 42CrMo4 / 42CrMo Amashanyarazi - Guhitamo kwisi yose kurwego rwa 12.9. Gukomera bihebuje, imbaraga z'umunaniro mwinshi, gukwirakwiza gukomera (39-44 HRC nyuma ya Q&T). Yubahiriza ISO 898-1, DIN EN 10263, hamwe nubuyobozi bwa ASTM.
- SCM440 (JIS) - Ikiyapani gihwanye na 42CrMo4. Yiganje mu nganda zo muri Aziya y'Uburasirazuba; hejuru yubuso burangije no kwihanganira ibipimo bya sock cap screw.
- 35CrMoV Amashanyarazi - Vanadium-yongerewe imbaraga zo kunanirwa kwambara no gukomera. Byatoranijwe kubushyuhe bwo hejuru cyangwa hejuru-vibrasiya yihuta ya porogaramu.
- 30CrNiMo8 Amashanyarazi - Nickel-chromium-molybdenum ibyuma kubintu biremereye cyane. Byerekanwe kubirere-byegeranye kandi bikomeye bya tekinoroji.
Gushyushya Ubushyuhe & Porogaramu
Kuzimya & Ubushyuhe (Q&T) hamwe no kugenzura gukomera (39-44 HRC). Porogaramu: disiki ya feri ya Caliper bolts, ibikoresho byimashini isobanutse neza, ibyuma byubatswe byubatswe, ibyuma bifata imitwe ya sock (DIN 912 / ISO 4762), imashini yihariye yinganda.
Byihuse Reba: Icyiciro na Byasabwe Ibikoresho
