GCr15 kub dov steel puag ncig tuav

GCr15 yog ib hom hlau uas siv los tsim cov pob thiab cov nplhaib ntawm cov kabmob. Cov khoom lag luam muaj cov yam ntxwv ntawm cov khoom sib xyaw-tshuaj lom neeg, qis feem pua ​​​​ntawm cov teeb meem tsis zoo, siab purity, zoo faib carbide, zoo nto zoo. Nws kuj muaj cov yam ntxwv ntawm ntau yam ntawm cov yas, ruaj khov kho cua sov zoo, zoo ib yam, thiab siab hardness, siab hnav tsis kam, siab zog ntawm kev qaug zog. Nws muaj cov cuab yeej machining zoo tom qab spheroidize annealing. GB GCr15 bearing steel yog GB standard Alloy Bearing steel, Nws muaj cov pa roj carbon zoo, alloy chromium, manganese steel. GB GCr15 cov khoom yog chromium, manganese alloy steel specification. GCr15 yog sib npaug rau AISI 52100, DIN 100Cr6. Cov ntawv thov feem ntau tuaj yeem hloov tau ib leeg.

Kev kho cua sov ntsig txog

• Annealing ntawm GCr15 Alloy bearing steel

Maj mam rhuab mus rau 790-810 ℃ thiab cia lub sij hawm txaus, cia cov hlau kom sov kom huv si, Tom qab ntawd maj mam txias hauv qhov cub. Cov txheej txheem sib txawv yuav tau txais qhov sib txawv hardness.Lub GCr15 bearing steel yuav tau Hardness MAX 248 HB (Brinell hardness).

• quenching thiab kub ntawm GCr15 Alloy bearing steel

Ua kom sov maj mam mus rau 860 ° C, ces quenching los ntawm cov roj tau 62 mus rau 66 HRc hardness. Kub kub tempering: 650-700 ℃, txias hauv huab cua, tau hardness 22 txog 30HRC. Tsawg kub tempering: 150-170 ℃, Txias hauv ari, tau 61-66HRC hardness.

• Kev ua haujlwm kub thiab txias ua haujlwm ntawm GCr15 Alloy bearing steel

GB GCr15 steel tuaj yeem ua haujlwm kub ntawm 205 txog 538 ° C, GCr15 Cov Kabmob steel tuaj yeem ua haujlwm txias ua haujlwm siv cov txheej txheem ua haujlwm hauv cov txheej txheem annealed lossis normalized.

Daim ntawv thov

GB GCr15 steel yog dav siv rau ntau yam kev siv hauv kev siv rau cov bearings hauv rotating machinery. Cov kev siv xws li lub cev valve, twj thiab fittings, lub siab load ntawm lub log, bolts, ob lub taub hau ntsia liaj qhov rooj, lub zog, sab hauv combustion engine. Hluav taws xob locomotives, tshuab cuab yeej, tsheb laij teb, steel dov khoom, tho txawv tshuab, railway tsheb, thiab mining machinery kis ncej ntawm steel pob, cov menyuam thiab ncej tes tsho, thiab lwm yam.
