20Cr kub dov steel ntawv

GB 20Cr alloy steel yog qhov zoo tshaj plaws Quenched thiab Tempered Alloy Cov Khoom Siv Hluav Taws Xob, Nws yog cov khoom siv qis qis, qis alloy chromium, molybdenum, nickel rooj plaub hardening hlau. Roj quenched & Tempered Hardness yog 28-34 HRc. GB 20Cr steel Annealing tus me nyuam hardenss tsawg dua 250HB.20Cr Nrog ib tug qis carbon cov ntsiab lus ntau, Yog li GB 20Cr alloy steel muaj zoo weldability.

GB 20Cr alloy steel sib npaug specification: ASTM A29/A29M, DIN EN 10083/3, JIS G4053 thiab GB/T 3077. GB 20Cr sib npaug steel puag ncig bar thiab tiaj tus tuav tau txiav rau koj qhov ntau thiab tsawg. Tuam Tshoj steel 20Cr kub dov thiab forged steel bar kuj tuaj yeem muab, muab cov cuab yeej zoo steel precision av cuab yeej steel bar rau koj qhov yuav tsum tau ua. GB 20Cr steel sib npaug cov khoom tuav tau muab rau hauv cov duab puag ncig, square thiab tiaj tus.
GB 20Cr alloy hlau yog qhov zoo tshaj plaws Quenched thiab Tempered Alloy Cov qauv hlau. Nws belongs rau lub siab zoo uas tsis muaj carbon, Tsawg alloy chromium, molybdenum, nickel rooj hardening hlau. Roj quenched & Tempered GB 20Cr Steel Hardness yog 28-34 HRc. GB 20Cr steel Annealing xa khoom hardens tsawg dua 250HB. Nrog rau cov ntsiab lus qis dua, GB 20Cr alloy steel sib npaug muaj qhov zoo weldability.
GB 20Cr forged steel bar thiab kub dov steel bar yog dav siv rau ntau yam kev siv hauv kev siv hauv tsheb thiab engineering industries rau cov cuab yeej thiab lwm yam khoom siv. Feem ntau siv rau hauv kev tsim khoom ntawm qhov kev thov yog siab dua, kev siv lub plawv nto hnav, nyob rau hauv seem hauv qab 30 hli los yog me me carburized qhov chaw ntawm cov duab nyuaj thiab load (roj quenching), xws li: kis tau tus mob, iav ncej, CAM, worm, piston. pin, claw clutch, thiab lwm yam

Piv nrog 15Cr steel, nws muaj zog dua thiab hardenability. Qhov tseem ceeb hardening txoj kab uas hla ntawm cov roj mus txog 4-22mm, thiab qhov tseem ceeb hardening txoj kab uas hla nyob rau hauv dej mus txog 11-40mm, tab sis nws toughness yog tsis zoo. Muaj kev nyiam rau cov nplej kom loj hlob, thiab ncaj qha quenching ntawm qhov txias muaj qhov cuam tshuam ntau dua rau kev cuam tshuam toughness. Yog li ntawd, tom qab carburizing, theem nrab quenching yog yuav tsum tau los txhim kho lub toughness ntawm ib feem tseem ceeb tsis temper brittleness; steel muaj siab txias strain plasticity thiab tuaj yeem kos rau hauv cov xwm txheej txias. ; Machinability yog zoo nyob rau hauv kub normalizing los yog quenching thiab tempering lub xeev, tab sis tsis zoo tom qab annealing; 20Cr yog pearlite, nrog zoo weldability, feem ntau tsis xav tau kev kho cua sov tom qab vuam, tab sis qhov thickness ntau dua 15 hli yuav tsum tau preheated ua ntej vuam Thaum nws ncav cuag 100 ~ 150 ℃, tempering kub kho tsis tas yuav tsum tau tom qab vuam.

Sib npaug ntawm 20Cr alloy Structure Steel

Kev kho cua sov ntsig txog

• Annealing ntawm 20Cr Alloy qauv steel

Maj mam rhuab mus rau 850 ℃ thiab cia lub sij hawm txaus, cia cov hlau kom huv si, ces txias maj mam nyob rau hauv lub cub tawg. 20Cr alloy steel yuav tau MAX 250 HB (Brinell hardness).

• Hardening ntawm GB Alloy qauv steel 20Cr

Ua ntej quenching rhuab maj mam mus rau 880 ° C, Tom qab txaus soaking ntawm no kub quench nyob rau hauv roj los yog dej. Kub kom sai li sai tau thaum cov cuab yeej ncav cuag chav sov. Thib ob quenching cua sov rau 780-820 ° C, ces quenching hauv roj los yog dej.

• Tempering ntawm 20Cr Alloy qauv hlau

Tshav kub rau 20 ° C, tom qab ntawd txias hauv dej lossis roj.Normal delivery hardness 179HB Min.

Daim ntawv thov

GB 20Cr steel yog dav siv rau ntau yam kev siv hauv kev siv hauv tsheb thiab engineering kev lag luam rau cov tswv cuab thiab lwm yam khoom siv. Feem ntau siv rau hauv kev tsim khoom ntawm qhov kev thov yog siab dua, kev siv lub plawv nto hnav, nyob rau hauv seem hauv qab 30 hli los yog me me carburized qhov chaw ntawm cov duab nyuaj thiab load (roj quenching), xws li: kis tau tus mob, iav ncej, CAM, worm, piston. pin, claw clutch, thiab lwm yam.; Rau kev kho cua sov deformation thiab siab abrasion tsis kam qhov chaw, yuav tsum muaj qhov siab zaus nto quenching tom qab carburizing, xws li modulus yog tsawg dua 3 ntawm lub iav, ncej, spline ncej, thiab lwm yam. Cov hlau no tuaj yeem siv rau hauv lub xeev quenched thiab tempered thiab siv nyob rau hauv kev tsim cov loj thiab nruab nrab nyob rau hauv kev cuam tshuam load nyob rau hauv nws ua hauj lwm qhov chaw, cov hlau no kuj yuav siv tau raws li ib tug tsawg carbon martensite steel quenching, ntxiv steel yield zog thiab tensile zog (kwv yees li 1.5 ~ 1.7 zaug). Cov kev siv xws li lub cev valve, twj thiab fittings, Ncej, lub siab load ntawm lub log, bolts, ob lub taub hau bolts, zog, thiab lwm yam

Tsis tu ncua loj thiab kam rau ua
