Pom cov hniav super audio zaus quenching khoom

Lub hardness thiab hnav tsis kam ntawm cov saw hniav yog ncaj qha proportional rau hardness thiab hnav tsis kam ntawm cov khoom siv high zaus quenching nrog super suab zaus. Txhawm rau txhim kho lub neej kev pab cuam ntawm cov saw hniav, nws yog ib qho tsim nyog los xyuas qhov hardness ntawm cov saw hniav thiab xaiv tus nqi tsim nyog. Lub quenching kub ntawm cov saw hniav yog 900 ℃, cov khoom siv rau cov saw hniav yog 65Mn, induction quenching cua sov kub ntawm qhov txias saw hniav yog 810 ~ 850 ℃; qhov induction quenching cua sov kub ntawm cov hniav kub yog 790 ~ 830 ℃. Qhov tob ntawm txheej txheej hardened ntawm qhov chaw yuav tsum tau txiav txim siab raws li qhov kev pabcuam ntawm qhov chaw. Qhov tob ntawm txheej hardened ntawm qhov txias pom hniav yog nyob nruab nrab ntawm 2mm thiab 6mm, thiab hardness tus nqi yog feem ntau ntawm 53 thiab 58HRC. Qhov kev txwv qis tuaj yeem raug tshem tawm; Qhov tob ntawm hardened txheej ntawm kub saw hniav Feem ntau ntawm 1-2mm thiab hardness tus nqi yog 58HRC.
