Lub hardness ntawm cov hlau pob yog txiav txim siab los ntawm steel pob ua los ntawm cov khoom sib txawv. Cov khoom siv hlau tsis sib xws suav nrog lub pob steel hlau, cov kabmob steel npas, carbon steel pob, thiab cov tawv alloy steel. Dab tsi yog yam ua rau lub hardnesses sib txawv ntawm cov hlau pob ntawm cov khoom sib txawv?
Lub hardness ntawm cov hlau pob yog cuam tshuam ncaj qha los ntawm cov txheej txheem kho cua sov, uas yog, quenching thiab tempering. Nyob rau hauv cov txheej txheem kev kho cua sov, cov kabmob steel pob undergoes quenching thiab tempering, thiab nws cov xim hlau sab hauv lub cev hloov pauv, uas ua rau muaj kev hloov ntawm qhov nyuaj. Txawm li cas los xij, pob tw hlau tsis tuaj yeem kho tau cua sov. Vim tias cov hlau tsis xeb yog austenitic steel, txheej txheem kev kho cua sov tsis tuaj yeem nqa tawm vim nws cov xwm txheej.
Vim tias qhov tshwm sim ntawm kev kho cua sov, qhov nyuaj ntawm cov kabmob lub npas kabmob hlau tuaj yeem ncav cuag HRC55-HRC62. Lub hardness ntawm cov hlau stainless pob uas tsis tuaj yeem kho cua sov yog HRC28-HRC35. Cov khoom steel nrog cov hardness sib txawv muaj cov ntawv thov sib txawv. Thaum koj yuav cov khoom steel, koj tuaj yeem xaiv siv cov khoom sib txawv raws li koj ib puag ncig.
316 stainless hlau pobhauv WeiChuang, qhov tseeb yog G5 ， G10 thiab G16.
Thiab pob Chrome feem ntau ua raws li GBT 308.1-2013 thiab ISO 3290-1: 2014 cov qauv.
