Dab tsi yog qhov corrosion tsis kam ntawm alloy steel round bar?

Thaum nws los txog rau qhov kev tiv thaiv corrosion ntawm cov hlau alloy puag ncig bar, hom hlau tshwj xeeb siv yuav tsum tau xav txog. Cov hlau puag ncig bar, xws li 4140 steel puag ncig bar, 42crmo4 steel puag ncig bar thiabaisi 4140 hlau puag ncig, paub txog lawv lub zog thiab kev ua haujlwm ntev. Txawm li cas los xij, lawv qhov kev tiv thaiv corrosion yuav sib txawv nyob ntawm cov khoom sib xyaw tshwj xeeb thiab kev kho qhov chaw.
Ib qho ntawm cov yam tseem ceeb uas ua rau muaj kev tiv thaiv corrosion ntawm cov hlau alloy puag ncig yog qhov muaj qee yam khoom sib xyaw. Piv txwv li, chromium feem ntau ntxiv rau cov hlau alloys kom txhim kho lawv txoj kev tiv thaiv corrosion. Qhov no pom tseeb tshwj xeeb hauv 4140 steel puag ncig, uas muaj ntau cov chromium, ua rau lawv tiv thaiv corrosion zoo heev. Tsis tas li ntawd, qhov muaj molybdenum nyob rau hauv42crmo4 puag ncig hlauntxiv txhim kho nws txoj kev tiv thaiv corrosion, ua rau nws tsim nyog rau cov ntawv thov hauv cov chaw ib puag ncig hnyav.
Ntxiv rau qhov sib xyaw ua ke, kev kho saum npoo ntawm cov hlau puag ncig kuj tseem ua lub luag haujlwm tseem ceeb hauv nws txoj kev tiv thaiv corrosion. Forged round steel bar dhau los ntawm cov txheej txheem tsim khoom tshwj xeeb los txhim kho nws txoj kev tiv thaiv corrosion. Los ntawm cov txheej txheem xws li kev kho cua sov thiab txheej saum npoo, qhov kev tiv thaiv corrosion ntawm cov hlau no tau txhim kho ntau heev, ua rau lawv haum rau ntau yam kev siv, suav nrog cov chaw hauv dej hiav txwv thiab kev lag luam.

Nws tsim nyog sau tseg tias txawm hais tias cov hlau sib xyaw ua ke feem ntau muaj kev tiv thaiv corrosion zoo, lawv tseem yuav raug rau qee hom corrosion, tshwj xeeb tshaj yog nyob rau hauv cov chaw corrosive. Yog li ntawd, kev saib xyuas kom zoo thiab kev tshuaj xyuas tsis tu ncua yog qhov tseem ceeb kom ntseeg tau tias cov hlau no ua haujlwm tau ntev.
Hauv kev xaus, qhov kev tiv thaiv corrosion ntawmhlau alloy puag ncig tuavxws li 4140 steel puag ncig bar, 42CrMo4 steel puag ncig bar, AISI 4140 puag ncig bar, forged puag ncig steel bar, thiab lwm yam yog cuam tshuam los ntawm cov yam xws li cov khoom sib xyaw ua ke thiab kev kho qhov chaw. Los ntawm kev nkag siab txog cov yam no thiab xaiv cov puag ncig zoo rau ib daim ntawv thov tshwj xeeb, cov tuam txhab tuaj yeem ua kom ntseeg tau tias muaj kev ua tau zoo thiab ntev hauv cov chaw muaj kuab paug.
