20Cr eshushu esongwa sheet steel

I-GB 20Cr ingxubevange Intsimbi yintsimbi yomgangatho ophezulu we-Quinched and Tempered Alloy Structural steel, Yeyomgangatho ophezulu wekhabhoni ephantsi, i-Low alloy chromium, i-molybdenum, intsimbi yenickel eqinisayo. I-oyile ecinyiweyo kunye nokuqina kokuqina yi-28-34 HRc. I-GB 20Cr yensimbi Ukuhanjiswa kwe-Annealing lukhuni ngaphantsi kwe-250HB.20Cr Ngoluhlu oluphantsi lwekhabhoni, Ke i-GB 20Cr i-alloy steel ine-weldability efanelekileyo.

I-GB 20Cr i-alloy steel equivalent specifikationer: ASTM A29 / A29M, DIN EN 10083 //3, JIS G4053 kunye ne-GB / T 3077. I-GB 20Cr i-bar yentsimbi elinganayo kunye nemivalo eyisicaba inokunqunyulwa kwiisayizi zakho ezifunekayo. I-China insimbi ye-20Cr eshushu egobileyo kunye ne-bar yensimbi edibeneyo nayo inokubonelelwa, inikezela ngesixhobo esiphezulu sensimbi esichanekileyo somgangatho wesixhobo sentsimbi kwi-tolerances yakho efunekayo. I-GB 20Cr imivalo yezinto ezilinganayo zentsimbi zibonelelwa ngokujikeleza, isikwere kunye neemilo ezisicaba.
I-GB 20Cr i-alloy Steel ngumgangatho ophezulu we-Quenched and Tempered Alloy Structural steel. Yeyomgangatho ophezulu wekhabhoni ephantsi, i-alloy chromium ephantsi, i-molybdenum, i-nickel case hardening steel. I-oyile ecinyiweyo kunye ne-Tempered GB 20Cr Ukuqina kwentsimbi yi-28-34 Hrc. GB 20Cr steel Annealing unikezelo lukhuni ngaphantsi kwe 250HB. Ngoluhlu olusezantsi lwekhabhoni, i-GB 20Cr i-alloy steel equivalents ine-weldability elungileyo.
I-GB 20Cr ibha yentsimbi edibeneyo kunye nentsimbi eshushu edibeneyo isetyenziselwa ngokubanzi usetyenziso olusetyenzisiweyo kwimizi-mveliso yeemoto kunye nobunjineli kubanini bezixhobo kunye namanye amacandelo anjalo. Ubukhulu becala lisetyenziswa ekwenzeni imfuno liphezulu, ubunzulu bomgangatho wokunxiba kwentliziyo, phantsi kwecandelo elingaphantsi kwe-30 mm okanye iindawo ezincinci ze-carburized zemilo entsonkothileyo kunye nomthwalo (ukucima ioyile), njengale: igiya yokuhambisa, i-gear shaft, i-CAM, intshulube, ipiston. iphini, i-claw clutch, njl

Xa kuthelekiswa nentsimbi ye-15Cr, inamandla aphezulu kunye nokuqina. I-diameter enzima yokuqina kwioli ifikelela kwi-4-22mm, kwaye i-diameter enzima yokuqina emanzini ifikelela kwi-11-40mm, kodwa ukuqina kwayo kubi. Kukho utyekelo lokukhula kweenkozo, kwaye ukucinywa ngokuthe ngqo ekupholiseni kunempembelelo enkulu kukuqina kwempembelelo. Ke ngoko, emva kokungcwatywa kwe-carburizing, ukucima okwesibini kuyafuneka ukuze kuphuculwe ukuqina kwenxalenye engundoqo ngaphandle kobushushu bomsindo; intsimbi inobunzima obuphezulu beplastiki kwaye inokutsalwa kwiimeko ezibandayo. ; I-Machinability ilungile phantsi kobushushu obuphezulu bokuqhelanisa okanye ukucima kunye nemeko yokufudumala, kodwa ihlwempu emva kokuba i-annealing; I-20Cr i-pearlite, ene-weldability elungileyo, ayifuni unyango lobushushu emva kwe-welding, kodwa iindawo ezinobunzima obungaphezulu kwe-15mm kufuneka zifudunyezwe ngaphambi kokuba zitshise xa zifikelela kwi-100℃ 150℃, unyango lobushushu alufunwa emva kwe-welding.

I-Equivalent Of 20Cr ialloy Structure Steel

Unyango Ubushushu Related

• Ukufakwa kwentsimbi ye-20Cr Alloy structural

Ukufudumala kancinane ukuya kwi-850 ℃ kwaye uvumele amaxesha aneleyo, vumela intsimbi ukuba ifudunyezwe ngokucokisekileyo, Emva koko upholise kancinci kwiziko. Intsimbi ye-alloy ye-20Cr iya kufumana MAX 250 HB (ubunzima beBrinell).

• Ukuqina kwe-GB Alloy yensimbi yesakhiwo 20Cr

Okokuqala ukucima ishushu ngokucothayo ukuya ku-880 ° C, Emva koko emva kokucwina okwaneleyo kulo bushushu kucima kwioli okanye emanzini. Ukucaphuka ngokukhawuleza xa izixhobo zifikelela kubushushu begumbi. Okwesibini ukucima ubushushu ukuya kwi-780-820 ° C, emva koko ukucima kwioli okanye emanzini.

• Ukufudumeza kwe-20Cr Ingxubevange yentsimbi yesakhiwo

Ukushisa kwi-20 ° C, emva koko upholile emanzini okanye kwi-oyile.Ubunzima obuqhelekileyo bokuhanjiswa kwe-179HB Min.

Usetyenziso

I-GB 20Cr yensimbi isetyenziswa ngokubanzi kwiintlobo ezahlukeneyo zezicelo kwimizi-mveliso yeemoto kunye nobunjineli kubanini bezixhobo kunye namanye amacandelo anjalo. Ubukhulu becala lisetyenziswa ekwenzeni imfuno liphezulu, ubunzulu bomgangatho wokunxiba kwentliziyo, phantsi kwecandelo elingaphantsi kwe-30 mm okanye iindawo ezincinci ze-carburized zemilo entsonkothileyo kunye nomthwalo (ukucima ioyile), njengale: igiya yokuhambisa, i-gear shaft, i-CAM, intshulube, ipiston. i-pin, i-claw clutch, njl. Kuba deformation unyango ubushushu kunye namalungu aphezulu abrasion ukuxhathisa, kufuneka high frequency umphezulu ucime emva carburizing, ezifana modulus ngaphantsi kwe 3 gear, shaft, spline shaft, njl esetyenziswa ekwenzeni ezinkulu kunye naphakathi phantsi komthwalo wempembelelo kwiindawo zakhe zokusebenza, olu hlobo lwentsimbi lunokusetyenziswa njengentsimbi ephantsi ye-carbon martensite yokucima intsimbi, inyusa ngakumbi amandla emveliso yentsimbi kunye namandla anyukayo (malunga ne-1.5 ~ 1.7 amaxesha). Usetyenziso oluqhelekileyo olunje ngemizimba yevalvu, iimpompo kunye nokufakelwa, i-Shaft, umthwalo ophezulu wevili, iibholithi, iibholiti ezinentloko ephindwe kabini, iigiya, njl.

Ubungakanani obuqhelekileyo kunye nokunyamezela
