Kev siv niaj hnub. Ob leeg carbon thiab alloy hlau yog haum rau rooj plaub-hardening; feem ntau mob me hlau yog siv, nrog tsawg carbon cov ntsiab lus, feem ntau tsawg dua 0.3% (saib qhov yooj yim- cov hlau yog xav paub ntxiv).
Ib yam li ntawd, cov hlau twg tuaj yeem hardened?
Hardened hlau. Lub sij hawm hardened steel feem ntau yog siv rau nruab nrab lossis siab carbon steel uas tau muab kev kho cua sov thiab ces quenching tom qab tempering.
Tom qab ntawd, lo lus nug yog, cov rooj plaub puas hardened? Case hardening ua ib qho nyuaj thiab hnav-resistant txheej txheej thaum khaws cia cov ductile-lub zog ntawm sab hauv. Lub thickness ntawm lub tawv txheej yog hu ua cas qhov tob. Muaj ob peb txoj kev ntawm case hardening rau iav , suav nrog lub tshuab nqus tsev carburizing, cua carburizing, thiab induction tawv.
Tsis tas li ntawd, cov ntaub ntawv hardened steel siv rau dab tsi?
Case hardening hlau yog ib txwm siv rau nce lub neej khoom. Qhov no yog qhov tshwj xeeb tshaj yog rau kev tsim cov khoom siv tshuab, carbon hlau forgings, thiab carbon hlau pinions. Case hardening kuj tseem siv tau rau lwm daim ntawv thov. Case hardening kuj hu ua nto hardening.
Koj puas tuaj yeem kho cov hlau me me?
Tsawg-carbon / non-alloy ( mob me ) steels tau ua case hardened los ntawm carburising los yog carbonitriding, tab sis ua tsis txhim kho lub zog tseem ceeb.

Cov neeg tshawb xyuas muaj sijhawm ntev npaum li cas tom qab hnub tshaj tawm tsab ntawv tshaj tawm los ua kom tiav cov ntaub ntawv tshawb xyuas los ntawm kev sib sau ua ke cov ntaub ntawv tshawb xyuas zaum kawg?
Cov ntaub ntawv txheeb xyuas ua tiav thiab zaum kawg yuav tsum tau muab sib dhos rau khaws cia raws li hnub tsis pub dhau 45 hnub tom qab hnub tshaj tawm daim ntawv tshaj tawm (hnub ua tiav cov ntaub ntawv)
Cov ntaub ntawv dab tsi tuaj yeem pwm tsis tuaj yeem loj hlob?
Pwm loj hlob thiab pub rau cov khoom siv organic xws li ntoo lossis paj rwb. Pwm yuav tsum tsis txhob loj hlob rau ntawm qhov chaw xws li yas, hlau los yog iav tshwj tsis yog tias muaj txheej roj lossis lwm yam khoom siv organic uas nws tuaj yeem pub rau
Cov ntaub ntawv dab tsi yuav tsum tsis txhob muaj hauv cov ntaub ntawv neeg ua haujlwm?
Piv txwv ntawm cov khoom uas yuav tsum tsis txhob muab tso rau hauv cov ntaub ntawv cov neeg ua haujlwm yog: Cov ntaub ntawv ua ntej ua haujlwm (nrog rau cov ntawv thov thiab rov pib dua) Cov ntaub ntawv tuaj koom lub hli. Whistleblower kev tsis txaus siab, sau ntawv tsim los ntawm kev tshawb nrhiav kev tsis txaus siab txog kev ntxub ntxaug, Ombuds, lossis Campus Climate
Dab tsi yog cov cuab yeej lossis cov txheej txheem siv los hloov cov ntaub ntawv kev ua haujlwm rau hauv cov ntaub ntawv kev ua haujlwm hauv cov txheej txheem tswj Scope?
Variance Analysis yog ib qho cuab yeej & Cov txheej txheem ntawm Kev Tswj Scope Txheej Txheem thiab Kev Ntsuas Kev Ua Haujlwm Ua Haujlwm (WPM) yog qhov tso tawm ntawm cov txheej txheem no
Tshooj 404 xav tau dab tsi ntawm kev tswj hwm cov ntaub ntawv tswj xyuas sab hauv tshawb fawb lub tuam txhab pej xeem thiab piav qhia txog kev tswj hwm cov ntaub ntawv ntawm kev tswj hwm sab hauv kom ua tau raws li cov cai ntawm ntu 40
Txoj Cai Sarbanes-Oxley xav kom cov kev tswj hwm ntawm cov tuam txhab pej xeem ntsuas qhov ua tau zoo ntawm kev tswj hwm sab hauv ntawm cov neeg tawm tswv yim rau kev tshaj tawm nyiaj txiag. Tshooj 404(b) xav kom ib lub tuam txhab tuav pov hwm tus neeg soj ntsuam los ua pov thawj rau, thiab tshaj tawm txog, kev tswj xyuas kev ntsuam xyuas ntawm nws cov kev tswj hwm sab hauv
