Lub hardness test yog ib qho nyuaj indenter hardness tester uas maj mam nias rau hauv qhov chaw ntawm cov qauv raws li cov xwm txheej, thiab tom qab ntawd sim qhov tob lossis qhov loj ntawm qhov indentation los txiav txim qhov hardness ntawm cov khoom.
Lub precision steel yeeb nkab hardness kuaj yog qhov yooj yim tshaj plaws, ceev tshaj plaws, thiab yooj yim tshaj txoj kev los kuaj cov khoom siv ntawm cov khoom. Kev ntsuam xyuas tsis muaj kev puas tsuaj muaj qhov zoo sib xws hauv kev sib raug zoo ntawm hardness thiab tensile lub zog qhov tseem ceeb. Tus nqi hardness ntawm cov khoom no tuaj yeem hloov mus rau hauv lub zog tensile, uas muaj qhov tseem ceeb tshaj plaws.
Vim qhov nyuaj ntawm kev sim tensile xeem thiab qhov yooj yim ntawm kev hloov hardness thiab lub zog, ntau thiab ntau tus neeg sim lawv tus kheej lub zog nrog tsawg dua hardness tests. Tshwj xeeb tshaj yog vim kev nce qib thiab kev tsim kho tshiab ntawm precision steel yeeb nkab hardness hauv kev tsim tshuab, qee cov ntaub ntawv uas yav tas los tsis tuaj yeem raug kuaj ncaj qha rau qhov tawv, xws li seamless steel kav, stainless hlau daim hlau, thiab stainless hlau strips, tam sim no tuaj yeem kuaj ncaj qha. rau hardness.
