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.
