20Cr otentha adagulung'undisa chitsulo pepala

GB 20Cr alloy Chitsulo ndi chapamwamba Chozimitsidwa ndi Tempered Alloy Structural steel, Ndi yapamwamba kwambiri ya carbon low,Low alloy chromium, molybdenum, nickel case harding steel. Mafuta Ozimitsidwa & Kutentha Kwambiri ndi 28-34 HRc. GB 20Cr zitsulo Annealing kubweretsa kulimba zosakwana 250HB.20Cr Ndi otsika carbon content osiyanasiyana, Choncho GB 20Cr aloyi zitsulo ndi weldability wabwino.

GB 20Cr aloyi zitsulo zofanana ndondomeko: ASTM A29/A29M, DIN EN 10083/3, JIS G4053 ndi GB/T 3077. GB 20Cr yofanana zitsulo bar ndi mipiringidzo lathyathyathya akhoza kudula kwa makulidwe anu ofunikira. China zitsulo 20Cr yotentha yokulungidwa ndi zitsulo zonyezimira imatha kuperekedwanso, kupereka chida chapamwamba chachitsulo cholondola kwambiri chachitsulo chazitsulo pazomwe mukufunikira. Mipiringidzo yachitsulo yofanana ya GB 20Cr imaperekedwa mozungulira, lalikulu komanso lathyathyathya.
GB 20Cr alloy Steel ndi mtundu wapamwamba kwambiri Wozimitsidwa ndi Tempered Alloy Structural steel. Ndi ya carbon low high quality, Low alloy chromium, molybdenum, nickel case kuumitsa chitsulo. Mafuta Ozimitsidwa & Kutentha kwa GB 20Cr Zitsulo Zolimba ndi 28-34 Hrc. GB 20Cr chitsulo Annealing yobereka imaumitsa zosakwana 250HB. Ndi mtundu wocheperako wa kaboni, zitsulo zofananira za GB 20Cr alloy zimakhala ndi weldability wabwino.
GB 20Cr yopangira zitsulo zopangira zitsulo ndi zitsulo zotentha zotentha zimagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito m'mafakitale amagalimoto ndi zomangamanga kwa omwe ali ndi zida ndi zina zotero. Zomwe zimagwiritsidwa ntchito kwambiri popanga zomwe zimafunidwa ndizokwera kwambiri, kulimba kwamtima kumavala pamwamba, pansi pa 30 mm kapena magawo ang'onoang'ono opangidwa ndi mawonekedwe ovuta ndi katundu (kuzimitsa mafuta), monga: zida zotumizira, shaft yamagetsi, CAM, nyongolotsi, pistoni. pin, claw clutch, etc

Poyerekeza ndi chitsulo cha 15Cr, ili ndi mphamvu zambiri komanso kulimba. Kuwumitsa kwakukulu mumafuta kumafika 4-22mm, ndipo kuuma kolimba m'madzi kumafika 11-40mm, koma kulimba kwake ndikosauka. Pali chizolowezi choti njere zikule, ndipo kuzimitsa molunjika pakuzizira kumakhudza kwambiri kulimba kwake. Chifukwa chake, pambuyo pa carburizing, kuzimitsa kwachiwiri kumafunika kuwongolera kulimba kwa gawo pachimake popanda kupsa mtima; Chitsulo chimakhala ndi pulasitiki yotentha kwambiri ndipo imatha kujambulidwa m'malo ozizira. ; Machinability ndi bwino kutentha kutentha normalizing kapena quenching ndi tempering boma, koma osauka pambuyo annealing; 20Cr ndi pearlite, ndi weldability wabwino, nthawi zambiri safuna chithandizo kutentha pambuyo kuwotcherera, koma mbali ndi makulidwe oposa 15mm ayenera preheated pamaso kuwotcherera Ikafika 100 ~ 150 ℃, kutentha kutentha mankhwala si chofunika pambuyo kuwotcherera.

Zofanana ndi 20Cr alloy Structure Steel

Kutentha mankhwala Zogwirizana

• Kuwonjezera 20Cr Alloy structural steel

Kutenthetsa pang'onopang'ono mpaka 850 ℃ ndikulola nthawi zokwanira, lolani chitsulo chitenthedwe bwino, Kenako kuziziritsa pang'onopang'ono mung'anjo. Chitsulo cha aloyi cha 20Cr chidzapeza MAX 250 HB (kuuma kwa Brinell).

• Kuumitsa kwa GB Aloyi structural zitsulo 20Cr

Kuzimitsa koyamba kutenthedwa pang'onopang'ono mpaka 880 ° C, Pambuyo pakuwuka kokwanira pa kutentha uku kuzimitsa mafuta kapena madzi. Kupsa mtima pamene zida zifika kutentha kwa chipinda. Chachiwiri kuzimitsa kutentha kwa 780-820 ° C, ndiye kuzimitsa mu mafuta kapena madzi.

• Kutentha kwa 20Cr Alloy structural chitsulo

Kutenthetsa mpaka 20 ° C, kenako kuziziritsa m'madzi kapena mafuta.Kulimba kwanthawi zonse 179HB Min.

Mapulogalamu

Chitsulo cha GB 20Cr chimagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito m'mafakitale amagalimoto ndi uinjiniya kwa okhala ndi zida ndi zida zina zotere. Zomwe zimagwiritsidwa ntchito kwambiri popanga zomwe zimafunidwa ndizokwera kwambiri, kulimba kwamtima kumavala pamwamba, pansi pa 30 mm kapena magawo ang'onoang'ono opangidwa ndi mawonekedwe ovuta ndi katundu (kuzimitsa mafuta), monga: zida zotumizira, shaft yamagetsi, CAM, nyongolotsi, pistoni. pin, claw clutch, etc.; Pakuti mapindikidwe kutentha mankhwala ndi mkulu abrasion kukana mbali, ayenera kukhala mkulu pafupipafupi padziko quenching pambuyo carburizing, monga modulus ndi zosakwana 3 wa giya, kutsinde, spline kutsinde, etc. Chitsulo ichi angagwiritsidwe ntchito kuzimitsidwa ndi mkwiyo boma ndi ntchito kupanga lalikulu ndi sing'anga pansi mphamvu katundu mu ntchito zake, zitsulo mtundu uwu angagwiritsidwenso ntchito ngati otsika mpweya martensite zitsulo quenching, kuonjezera kuwonjezeka zitsulo zokolola mphamvu ndi kumakokedwa mphamvu kuchuluka (pafupifupi 1.5 ~ 1.7 zina). Zomwe zimagwiritsidwa ntchito monga matupi a valve, mapampu ndi zopangira, Shaft, katundu wochuluka wa gudumu, mabawuti, ma bawuti okhala ndi mitu iwiri, magiya, ndi zina zambiri.

Kukula kokhazikika ndi Kulekerera

Chitsulo mbale: makulidwe 5mm - 3000mm x M'lifupi 100mm - 3500mm

Chitsulo Hexagonal bar: Hex 5mm - 105mm

Ma 20Cr ena sanatchule kukula kwake, pls  lemberani gulu lathu lodziwa zamalonda.

Kukonza

GB 20Cr aloyi zitsulo zozungulira bala ndi magawo athyathyathya amatha kudulidwa kukula kwanu kofunikira. 20Cr alloy steel ground bar itha kuperekedwanso, kupereka chida chapamwamba kwambiri chachitsulo chachitsulo chachitsulo chachitsulo chazitsulo pazomwe mukufunikira. Chitsulo cha GB 20Cr chimapezekanso ngati Ground Flat Stock / Gauge Plate, mumiyeso yokhazikika komanso yosavomerezeka.
