ASTM 20crmo cov txheej txheem phaj

20crmnmo alloy steel kuj tseem hu ua 20Cmnmo carburized steel, nws lub zog yog siab dua li 15crmnmo steel, cov khoom siv me me thiab cov kws kho mob yog siab dua 20crmnti steel. Cov hlau muaj zoo machinability, deformation me me thiab zoo nkees tsis kam. Nws muaj cov khoom siv kho tshuab thiab kub tsis zoo rau kev kub ntxhov tom qab lub zog thiab hnav tsis zoo, tab sis nws yooj yim rau tawg thaum sib tsoo. Cov hlau muaj cov tsis zoo weldability thiab yog tsim nyog rau kev tiv thaiv vuam. Nws yuav tsum tau ua ntej vuam thiab tempered tom qab vuam. Cov hlau yog tsuas yog siv nyob rau hauv kev tsim cov khoom tshwj xeeb ntawm cov tsheb thiab cov dav hlau, nrog rau cov ntawm cov shafts thiab pistons.

Lub zog siab thiab hardness. Nws lub zog yog siab tshaj qhov ntawm 15crmnmo steel, nrog hardness ntau dua thiab lub zog.
Zoo toughness thiab kev cuam tshuam tawv. Cov hlau muaj cov khoom siv nruj thiab cuam tshuam nyuaj, thiab yog qhov haum rau ntau qhov chaw ua haujlwm thiab siv cov xwm txheej nyuaj.
Zoo kub thiab corrosion tsis kam. Cov hlau tuaj yeem tswj cov ruaj khov zoo thiab ua kom ruaj khov nyob rau hauv ib puag ncig kub siab thiab corrosive.
Zoo weldability thiab machinability. Cov hlau tuaj yeem welded thiab machined kom yooj yim tsim thiab txij nkawm.
Tsis tas li ntawd, 20crmo alloy steel kuj muaj cov hnav zoo, nkees tsis kam thiab lwm yam ntxwv, tau siv dav hauv kev tsim khoom, aerospace thiab lwm hom teb.

Peb muab ASTM 20crmo cov phiaj xwm phaj thiab lwm cov qib ntawm cov khoom lag luam steel hlau siv, kom paub meej tias cov khoom lag luam zoo, yog tias koj xav tau thov hu rau kuv.
