20Cr ishyushye ryurupapuro

GB 20Cr alloy Steel nicyuma cyiza cyo kuzimya no gutondekanya Alloy Structural ibyuma, Nibintu byujuje ubuziranenge bwa karubone yo hasi, Chromium nkeya, molybdenum, nikel ikomera ibyuma. Amavuta yazimye & Ubushyuhe bukomeye ni 28-34 HRc. GB 20Cr ibyuma Annealing itanga gukomera bitarenze 250HB.20Cr Hamwe nibintu biri munsi ya karubone, So GB 20Cr alloy ibyuma bifite gusudira neza.

GB 20Cr alloy ibyuma bihwanye nibisobanuro: ASTM A29 / A29M, DIN EN 10083 / 3, JIS G4053 na GB / T 3077. GB 20Cr ihwanye nicyuma kizengurutsa ibyuma hamwe nibibari binini birashobora kugabanywa mubunini bwawe busabwa. Ubushinwa ibyuma 20Cr bishyushye kandi byahimbwe ibyuma nabyo birashobora gutangwa, bitanga ibikoresho byujuje ubuziranenge ibyuma byerekana neza ibyuma byubutaka kugirango wihangane. GB 20Cr ibyuma bihwanye nibikoresho bitangwa muburyo buzengurutse, kare kandi buringaniye.
GB 20Cr alloy Steel nicyiza cyo hejuru kizimye kandi gishyushye Alloy Structural ibyuma. Nibintu byujuje ubuziranenge bwa karubone, chromium nkeya, molybdenum, nikel ikomera ibyuma. Amavuta yazimye & Tempered GB 20Cr Icyuma gikomeye ni 28-34 HRc. GB 20Cr ibyuma Annealing itanga gukomera munsi ya 250HB. Hamwe na karubone yo hasi iringaniye, GB 20Cr ibangikanya ibyuma bingana bifite gusudira neza.
GB 20Cr yahimbwe ibyuma nibyuma bishyushye bikoreshwa cyane mubikorwa bitandukanye bikoreshwa mubikorwa byimodoka nubwubatsi kubafite ibikoresho nibindi bikoresho. Ahanini ikoreshwa mugukora ibisabwa irarenze, ubukana bwimyambarire yumutima, munsi yicyiciro kiri munsi ya mm 30 cyangwa uduce duto twa karburize yibice bigoye kandi biremereye (kuzimya amavuta), nka: ibikoresho byohereza, shitingi, CAM, inyo, piston pin, claw clutch, nibindi

Ugereranije nicyuma cya 15Cr, gifite imbaraga zo hejuru no gukomera. Diameter ikomeye yo gukomera mumavuta igera kuri 4-22mm, naho diameter ikomeye yo gukomera mumazi igera kuri 11-40mm, ariko ubukana bwayo ni bubi. Hariho impengamiro yo gukura, kandi kuzimya mu gukonjesha bigira ingaruka zikomeye ku gukomera. Kubwibyo, nyuma ya carburizing, kuzimya kabiri birasabwa kunoza ubukana bwigice cyibanze nta kurakara; ibyuma bifite plastike ikonje kandi irashobora gukururwa mubihe bikonje. ; Imashini ni nziza mugihe cy'ubushyuhe bwo hejuru busanzwe cyangwa kuzimya no gutuza, ariko bikennye nyuma ya annealing; 20Cr ni pearlite, hamwe no gusudira neza, mubisanzwe ntabwo ikenera kuvurwa nubushyuhe nyuma yo gusudira, ariko ibice bifite umubyimba urenze 15mm bigomba gushyuha mbere yo gusudira Iyo bigeze 100 ～ 150 ℃, ubushyuhe bwubushyuhe ntibusabwa nyuma yo gusudira.

Ibikoresho bya mashini

Bingana na 20Cr alloy Imiterere Imiterere

Kuvura ubushyuhe Bifitanye isano

• Annealing ya 20Cr Alloy ibyuma byubaka

Buhoro buhoro ushushe kuri 850 ℃ hanyuma wemere ibihe bihagije, reka ibyuma bishyushye neza, Hanyuma bikonje buhoro mumatanura. Ibyuma 20Cr bivanze bizabona MAX 250 HB （Gukomera kwa Brinell）.

• Gukomera kwa GB Alloy ibyuma byubaka 20Cr

Banza kuzimya bishyushye buhoro kugeza kuri 880 ° C, Hanyuma nyuma yo gushiramo bihagije kuri ubu bushyuhe bwamavuta cyangwa amazi. Ubushyuhe mugihe ibikoresho bigeze kubushyuhe bwicyumba. Ubushyuhe bwa kabiri bwo kuzimya kugeza kuri 780-820 ° C ， hanyuma kuzimya amavuta cyangwa amazi.

• Ubushyuhe bwa 20Cr Alloy ibyuma byubaka

Shyushya kuri 20 ° C, hanyuma ukonje mumazi cyangwa mumavuta.ubukomere budasanzwe 179HB Min.

Porogaramu

GB 20Cr ibyuma bikoreshwa cyane mubikorwa bitandukanye bikoreshwa mu nganda z’imodoka n’ubwubatsi kubafite ibikoresho nibindi bikoresho. Ahanini ikoreshwa mugukora ibisabwa irarenze, ubukana bwimyambarire yumutima, munsi yicyiciro kiri munsi ya mm 30 cyangwa uduce duto twa karburize yibice bigoye kandi biremereye (kuzimya amavuta), nka: ibikoresho byohereza, shitingi, CAM, inyo, piston pin, claw clutch, nibindi.; Kubijyanye no kuvura ubushyuhe hamwe nibice birwanya abrasion, bigomba kuba kuzimya hejuru yumuriro nyuma yo gutwika, nka modulus iri munsi ya 3 yibikoresho, shitingi, umugozi, nibindi. Iki cyuma kirashobora gukoreshwa muburyo bwazimye kandi burakaye kandi ikoreshwa mugukora ibicuruzwa binini n'ibiciriritse munsi yumutwaro mubice byakazi bye, ubu bwoko bwibyuma nabwo burashobora gukoreshwa nkumuriro muto wa karubone martensite kuzimya ibyuma, bikarushaho kongera ingufu zibyuma byimbaraga nimbaraga ziyongera (inshuro 1.5 ~ 1.7). Porogaramu zisanzwe nkimibiri ya valve, pompe nibikoresho, Shaft, umutwaro muremure wibiziga, bolts, imitwe ibiri-imitwe, ibikoresho, nibindi

Ingano isanzwe no kwihanganirana

Uruziga ruzengurutse ibyuma: Diameter Ø 5mm - 3000mm

Isahani yicyuma: Ubunini 5mm - 3000mm x Ubugari 100mm - 3500mm

Icyuma cya Hexagonal: Hex 5mm - 105mm

Abandi 20Cr ntibagaragaje ingano, pls hamagara itsinda ryacu ryo kugurisha inararibonye.

Gutunganya

GB 20Cr ivanze ibyuma bizenguruka umurongo hamwe nibice birashobora kugabanywa kubunini bwawe busabwa. 20Cr alloy ibyuma byubutaka birashobora kandi gutangwa, bitanga ibikoresho byujuje ubuziranenge ibyuma byerekana neza ibyuma byubutaka kubikoresho byihanganirwa. GB 20Cr ibyuma nabyo birahari nka Ground Flat Stock / Isahani ya Gauge, mubipimo bisanzwe kandi bitujuje ubuziranenge.
