35NCD16 Anneal Alloy Steel Bar
Hom: Phaj / Round bar / Pav ca bar
Tus me nyuam lub sij hawm: Annealed dub nto / Tig kaj nto
Khoom Description
35NCD16 Alloy Steel Bars yog ib qho kev qhia ntau yam. Kev siv cov khoom siv no muaj ntau heev thiab suav nrog cov hauv qab no:
Hauv Engineering:Ultra siab tensile daim ntaub ntawv, shafts, gears, bolts, spline shafts, crusher shafts, eccentric shafts, nyuaj hnav bushes thiab siab cuam tshuam pistons
Hauv mining:Pob zeb laum, khob tawm cov khoom, zeb hammers, cyclone daim hlau, siab tensile mechanical thiab thermal shock applications
Hauv Tooling:Yas extrusion tuag, tuag bolster rings thiab xuas nrig ntaus
35NCD16 Alloy Steel Nta thiab kev faib tawm
35NCD16 yog ib qho kim steel specification tsis yog vim hais tias ntawm high alloying ntsiab tab sis kuj cov refining txoj kev siv kom cov hydrogen (H) cov ntsiab lus ntawm cov hlau kom tsawg tshaj li ob feem ntawm ib lab, (H=tsawg dua los yog sib npaug. rau 2PPM). Nws raug nqi ntau dua li lwm yam BS 970 specifications
Nws yog 1500 MPa yam tsawg kawg nkaus tensile steel, cua hardening nyob rau hauv seem mus txog 65mm txoj kab uas hla.Tshwj xeeb yog pom zoo rau intricately zoo li tus qhov chaw uas ib tug huab cua hardening hlau yog nyiam.
35NCD16 alloy hlau tuaj yeem ua cov ntaub ntawv hardened, tuaj yeem ua tau carburised thiab induction hardened los yog luv luv (nplaim tawv).
Kev kho cua sov, suav nrog tus nqi ntawm cov cua sov, lub sijhawm txias thiab ntub dej yuav sib txawv vim muaj ntau yam xws li cov duab thiab qhov loj ntawm txhua EN30B steel tivthaiv.

35NCD16 Alloy Steel Thaum tshav kub kub kho
| Forging | Ua tib zoo rhaub cov hlau kom zoo rau qhov ntsuas kub ntawm 1000-1100 degree, tsau kom zoo. Tom qab forging, txias maj mam nyob rau hauv ib lub qhov cub rau 100 degree siab tshaj plaws thiab anneal tam sim ntawd. |
| Annealing | Txhawm rau kom tau txais cov xwm txheej softest kub ua tib zoo rau 630-650 degree . Soak tsawg kawg yog 2 teev, tom qab ntawd txias hauv qhov cub lossis hauv huab cua. Nws raug nquahu kom rov kho qhov kev kho no kom tau txais cov yam ntxwv zoo tshaj plaws ntawm machining. |
| Kev ntxhov siab | Qhov twg cov kev ua haujlwm machining tau hnyav heev, peb pom zoo kom txo qis EN30B alloy steel ua ntej ua tiav machining thiab hardening. Ua tib zoo ua kom sov rau 630-650 degree ces txias hauv qhov cub lossis hauv huab cua. |
| Hardening | Thaum tshav kub kub sib npaug mus rau 810-830 degree thiab thaum so kom huv si ntawm qhov kub no txias hauv huab cua lossis quench hauv roj raws li qhov loj. Hardening los ntawm nruab nrab ntsev da dej yuav pab tiv thaiv kom txhob scaling los yog decarburisation thiab xav kom pom zoo. Ua ntej cua sov ntawm 300-400 degree, nce mus rau qhov kub thiab txias ntawm 810-830 degree, quench rau ntsev sawv ntawm 300-320 degree . Tshem tawm thiab txias hauv huab cua. Tsis tas li ntawd, cov cuab yeej tuaj yeem ua lub tshuab nqus tsev. Yog tias xav tau, cov cuab yeej hardened thiab tempered tuaj yeem ua cyanide hardened los muab cov ntaub ntawv ntiav carburised rau qhov chaw tuag nrog cov nqi hardness nce mus txog Rockwell C56-60. Kub kom sai li sai tau thaum cov cuab yeej siv tes sov. |
| Tempering | Rov ua kom sov rau qhov cuam tshuam tempering. Soak yam tsawg kawg 2 teev rau 25 hli ntawm kev txiav txim. Tshem tawm ntawm qhov cub thiab txias hauv huab cua. Tempering ntawm 275-450 degree tsis qhia tias tempering nyob rau hauv qhov ntau no yuav txo qhov cuam tshuam tus nqi.
