1, HR

stainless hlau Guallo hardness kuaj, zoo li Brinell hardness xeem, yog cov kev kuaj indentation. Qhov txawv yog tias nws yog ntsuas qhov tob ntawm indentation, Luo hardness test yog tam sim no dav siv txoj kev, uas HRC hauv cov yeeb nkab steel txheem yog thib ob tsuas yog Brinell hardness HB, Luo hardness yuav siv rau kev txiav txim cov hlau khoom los ntawm tsis tshua muaj muag los nyuaj heev, nws ua rau Brinell txujci tsis yog, yooj yim dua li Brinell txujci, tuaj yeem ncaj qha los ntawm Hardness lub tshuab dial nyeem ntawv Tab sis, vim nws qhov me me, qhov hardness value is not as accurate as Brinell txujci.


2, Brinell hardness

nyob rau hauv txoj hlua hlau tsis xa tawm, Brinell hardness yog feem ntau siv ntau, feem ntau nrog qhov inch diameter los qhia tias qhov hardness ntawm cov khoom, ob qho tib si intuitive thiab yooj yim, tab sis rau qhov nyuaj lossis thinner steel yeeb nkab tsis muaj feem xyuam.


3, Vickers hardness stainless hlau Tauvi hardness test kuj yog ib txoj kev ntsuas indentation, siv tau los txiav txim siab nyias cov ntaub ntawv hlau thiab txheej txheej hardness, nws muaj qhov tseem ceeb ntawm Brinell, Rockwell txujci, thiab kov yeej lawv cov kev ua yuam kev, tab sis tsis raws li yooj yooj yim li Luo txoj kev, Vickers txoj kev tsis tshua muaj siv nyob rau hauv cov yeeb nkab steel qauv.


4, hardness kuaj stainless steel yeeb nkab puab inch ntawm ntau tshaj 6.0 hli, phab ntsa thickness nyob rau hauv 13mm annealing stainless hlau yeeb nkab, yuav siv tau w-b75 hom Webster hardness meter, nws kev kuaj yog heev ceev, yooj yim, haum rau stainless hlau yeeb nkab ua ceev nruj tsis muaj kev tshuaj ntsuam xyuas. Stainless hlau tube inch ntau dua 30 hli, phab ntsa thickness ntau dua 1.2 hli stainless hlau yeeb nkab, kev siv ntawm Luo hardness meter, kuaj HRB, HRC hardness. Stainless hlau tube inch ntau dua 30 hli, phab ntsa thickness tsawg dua 1.2 hli stainless hlau yeeb nkab, kev siv ntawm qhov chaw Luo hardness meter, kuaj HRT los yog cov ntaubntawv povthawj siv zog, puab lub cev tsawg tshaj 0 hli, ntau dua 4.8mm stainless hlau yeeb nkab, kev siv cov yeeb nkab tshwj xeeb Luo hardness meter, kev ntsuas hr15t hardness, Thaum cov kab uas hlaus tsis xeb hlau loj tshaj 26 hli, Lub zog ntawm cov phab ntsa hauv cov yeeb nkab tseem tuaj yeem kuaj nrog Rockwell los yog qhov chaw Roche hardness meter.
