Raws li cov khoom siv hlau zoo, 20CrMn steel muaj cov khoom zoo heev thiab tau siv dav hauv ntau qhov chaw. Hauv nws lub npe, "20" sawv cev rau cov ntsiab lus chromium ntawm kwv yees li 20%, thiab "Mn" sawv cev rau cov ntsiab lus manganese txog li 1%. Qhov sib ntxiv ntawm cov ntsiab lus no muab 20CrMn steel tshwj xeeb cov khoom siv thiab hnav tsis kam.

Ua ntej, cov yam ntxwv ua haujlwm ntawm 20CrMn steel
20CrMn steel muaj cov yam ntxwv tseem ceeb hauv qab no:
1. Zoo heev lub zog thiab toughness: 20CrMn steel tuaj yeem tau txais lub zog ntau dua thiab tawv tom qab kev kho cua sov kom zoo, thiab tsim nyog rau lub sijhawm uas muaj kev kub ntxhov thiab cuam tshuam.
2. Zoo hnav tsis kam: Vim muaj cov ntsiab lus xws li chromium thiab manganese, 20CrMn steel muaj kev hnav zoo heev thiab tsim nyog rau kev tsim khoom hnav-tiv taus xws li iav, bearings, thiab lwm yam.
3. Kev kho cua sov zoo: 20CrMn steel tuaj yeem yooj yim tau txais cov khoom siv kho tshuab los ntawm kev kho cua sov, muaj zog yoog raws, thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom sib txawv.

Thib ob, daim ntawv thov teb ntawm 20CrMn steel
20CrMn steel muaj ntau yam kev siv hauv kev lag luam, feem ntau suav nrog tab sis tsis txwv rau cov hauv qab no:
1. Mechanical manufacturing: 20CrMn steel feem ntau yog siv los tsim ntau yam khoom siv kho tshuab, xws li lub zog, kis tau tus mob, thiab lwm yam. Nws lub zog zoo heev thiab hnav tsis kam ua rau nws nrov hauv kev tsim khoom siv tshuab.
2. Kev tsim tsheb: Hauv kev lag luam tsheb, 20CrMn steel feem ntau yog siv los tsim cov khoom sib kis, xws li lub zog, crankshafts, thiab lwm yam., ua si nws zoo heev hnav tsis kam thiab lub zog zoo.
3. Aerospace teb: Vim hais tias 20CrMn steel muaj kev kho cua sov zoo thiab lub zog siab, nws kuj tau siv dav hauv aerospace teb los tsim ntau yam khoom muaj zog.
4. Engineering machinery: 20CrMn steel kuj tau siv dav hauv kev tsim cov tshuab engineering, siv los tsim cov khoom hnav-tiv taus xws li excavators thiab loaders los tiv thaiv kev ua haujlwm hnyav thiab ua haujlwm ntau zaus.

Nyob rau hauv cov ntsiab lus, 20CrMn steel yog dav siv nyob rau hauv ntau lub teb xws li machinery manufacturing, tsheb tsim, aerospace, thiab engineering machinery vim nws zoo heev zog, toughness, thiab hnav tsis kam, thiab tau dhau los ua ib qho tseem ceeb ntawm cov ntaub ntawv tseem ceeb hauv cov teb no.
