1. Queeded thiab Tempered Steel
Lub hardness ntsuas ntawm quenched thiab tempered steel tsuas yog siv rockwell hardness tester HRC nplai. Yog tias cov ntaub ntawv yog nyias thiab hrc nplai tsis haum, HRA nplai yuav siv tau. Yog tias cov khoom siv yog thinner, nto rockwell hardness nplai HR15N, HR30N, lossis HR45N tuaj yeem siv tau.
2. Saum npoo hardened hlau
Hauv kev lag luam ntau lawm, qee zaum qhov tseem ceeb ntawm cov neeg ua haujlwm yog yuav tsum muaj kev ua haujlwm zoo, thaum lub nplaim kuj yuav tsum tau muaj kev tawv ntau thiab hnav tsis kam. Hauv qhov no, zaus quenching, tshuaj carburization, nitriving, carbonitriving, carbonitriving, carbonitriving, carbonitring kev kho mob saum npoo av rau lub workpiece. Lub thickness ntawm saum npoo hardening txheej yog feem ntau ntawm ob peb millimeters thiab ob peb millimeters. Rau cov ntaub ntawv nrog cov txheej txheej tawv tawv tawv tawv, cov nplai HRC tuaj yeem siv los ntsuas lawv lub hardness. Rau nruab nrab thickness nto Hardening cov hlau, HRD lossis HRA teev tuaj yeem siv tau. Rau qhov saum npoo av hardening txheej, saum npoo Rockwell Hardness Nplai ntawm HR15N, HR30N, thiab HR45N yuav tsum tau siv. Rau thinner nto hardenes txheej, micro vickers hardness teser lossis tus ntsuas ultrasonic hardness yuav tsum tau siv.
3. Annealed steel, cov hlau qub, hlau me
Ntau cov khoom siv hlau tsim tawm hauv anealed lossis ib txwm muaj lub xeev, thiab ib co khaub phaj txias dov steel kuj tseem tau muab qhab nia raws li kev sib txawv ntawm kev ua tiav. Lub hardness ntsuas ntawm ntau cov pob annealed feem ntau siv teev teev, thiab qee zaum HRF teev kuj tau siv rau softer thiab thinner daim hlau. Rau daim hlau nyias, rockwell hardness tes testers hr15t, hr30t, thiab hr45t nplai yuav tsum tau siv.
4. Stainless hlau
Cov khoom siv hlau stainless feem ntau yog muab rau hauv cov xeev xws li annealing, quenching, Tempering, thiab kev daws teeb meem. Cov Qauv Hauv Tebchaws Qhia kom meej qhia cov lus sib raug thiab qhov nyuaj qis, thiab kev sim ua pob zeb Hardness Feem ntau siv Rockwell Hardness Tester HRC lossis HRB teev. Lub HRB nplai yuav tsum tau siv rau cov hlau tsis muaj zog thiab cov pa hluav taws xob lossis daus ntawm cov hlau hluav taws xob yuav tsum siv rau cov ntaub ntawv hlau hluav taws xob hauv Rockwell
5. Forged Steel
Lub brinell hardness hardness ntsuas feem ntau yog siv rau forged steel, vim tias lub microstructure ntawm forged steel tsis txaus, thiab brinell hardness ntsuas indentation loj. Yog li ntawd, Brinell Hardness Ntsuas yuav pom cov txiaj ntsig zoo ntawm microstructure thiab cov khoom ntawm txhua feem ntawm cov khoom.
6. Nrum Hlau
Cov ntaub ntawv cam khwb cia feem ntau pom los ntawm cov qauv coaten thiab cov noob ntxhib, yog li brinell hardness hardness feem ntau saws. Lub Rockwell Hardness Tester tuaj yeem siv rau hardness ntsuas ntawm qee cov khoom siv hlau pov cov hlau. Qhov twg tsis muaj thaj chaw txaus ntawm ntu me me
Hard Mallleable kas fes hlau cov khoom lag luam feem ntau siv Rockwell Hardness Tester HRC. Yog tias cov khoom siv tsis sib xws, ntau cov ntaub ntawv tuaj yeem ntsuas thiab tus nqi nruab nrab tau coj.
7. Sintered Carbide (Hard Alloy)
Lub hardness ntsuas ntawm cov khoom siv nyuaj tag nrho feem ntau tsuas yog siv Rockwell Hardness Tester HRA nplai.
