16MnCr5 Alloy Steel Forging Gears nrog CNC Machining

Kev taw qhia txog cov khoom siv

16MnCr5 alloy steel, zoo siab tsis tshua muaj hlau hlau los ntawm lub teb chaws Yelemees, yog lub npe hu ua tus neeg sawv cev ntawm kev ua tau zoo iav hlau. Hauv Suav teb, nws feem ntau hu ua 16CrMnH (raws li GB / T 5216-2004 tus qauv). Cov khoom siv no tau nyob ib qho chaw hauv thaj chaw high-endiav castingsmanufacturing vim nws zoo heev carburizing kev ua tau zoo, zoo heev hardenability thiab zoo machinability. Tom qab carburizing thiab quenching kev kho mob, qhov hardness ntawm 16MnCr5hlau forgingsyog ho txhim kho thiab hnav tsis kam yog zoo heev. Nws yog ib qho kev xaiv zoo tshaj plaws rau kev tsim cov khoom uas dais hnyav thiab kev sib txhuam tsis tu ncua.

Tshuaj muaj pes tsawg leeg thiab microstructure

Cov tshuaj muaj pes tsawg leeg ntawm 16MnCr5 alloy steel tau ua tib zoo sib xyaw kom ntseeg tau tias nws cov khoom siv zoo heev:
C: 0.14% ~ 0.19%, muab qhov tsim nyog lub zog thiab hardness rau hlau.
Si: ≤0.40%, pab txhim kho thermal stability thiab oxidation tsis kam ntawm hlau.
Mn: 1.00% ~ 1.30%, txhim khu lub hardenability thiab toughness ntawm hlau.
Cr: 0.80% ~ 1.10%, txhim kho corrosion kuj thiab hnav tsis kam ntawm hlau.
S: ≤0.035%, tswj cov thermal brittleness ntawm hlau.
P: ≤0.035%, txhim kho lub zog thiab ua haujlwm rau atmospheric corrosion ntawm hlau.

Mechanical zog

16MnCr5 alloy steel muaj cov khoom siv zoo heev thiab tuaj yeem ua tau raws li qhov xav tau ntawm kev siv zog nruj:
Tensile zog (MPa): 880-1180, ua kom muaj kev ruaj ntseg ntawm qhov chaw thaum raug lub zog tensile loj.
Conditional yield zog (MPa): feem ntau nyob ib ncig ntawm 635 (tus nqi tshwj xeeb yuav txawv nyob ntawm cov txheej txheem kho cua sov), ua kom cov khoom muaj peev xwm thauj khoom ua ntej yielding.
Elongation (%): 9, qhia tias cov khoom muaj cov yas zoo thiab tsis yooj yim tawg thaum raug quab yuam.
Kev txo qis (%): 57 (los yog 35, nyob ntawm seb qhov kev kuaj mob thiab qhov loj me), qhia txog cov khoom siv lub zog nqus dej ua ntej tawg.
Impact toughness tus nqi (J / cm²): 34, ua pov thawj cov khoom toughness thaum raug cuam tshuam.
Hardness: ≤297 HB, muab lub hauv paus zoo rau kev kho mob tom qab carburizing thiab quenching.
