Qhia kom meej stainless hlau kav feem ntau siv peb hardness indexes ntawm Brinell, Rockwell thiab Vickers los ntsuas lawv hardness.
Brinell hardness Ntawm cov qauv stainless hlau yeeb nkab, Brinell hardness yog siv dav tshaj plaws, thiab hardness ntawm cov khoom feem ntau qhia los ntawm indentation txoj kab uas hla, uas yog intuitive thiab yooj yim. Tab sis nws tsis haum rau cov kav hlau steel ntawm cov tawv tawv los yog nyias nyias.
Rockwell hardness The Rockwell hardness test of stainless steel yeeb nkab yog tib yam li Brinell hardness test, uas yog indentation test method. Qhov txawv yog tias nws ntsuas qhov tob ntawm qhov indentation. Rockwell hardness test tam sim no yog ib txoj kev siv dav, ntawm cov HRC tsuas yog thib ob rau Brinell hardness HB hauv cov qauv steel yeeb nkab. Rockwell hardness tuaj yeem siv los ntsuas cov khoom siv hlau los ntawm cov mos mos mus rau qhov nyuaj heev. Nws ua rau qhov sib txawv ntawm Brinell txoj kev thiab yooj yim dua li txoj kev Brinell. Tus nqi hardness tuaj yeem nyeem ncaj qha los ntawm lub xov tooj ntawm lub tshuab hardness. Txawm li cas los xij, vim nws qhov me me indentation, tus nqi hardness tsis yog raws li txoj kev Brinell. Vickers hardness Lub Vickers hardness test ntawm stainless hlau raj kuj yog ib qho kev xeem indentation, uas yuav siv tau los txiav txim siab hardness ntawm nyias hlau cov ntaub ntawv thiab nto txheej. Nws muaj qhov zoo ntawm Brinell thiab Rockwell txoj kev, thiab kov yeej lawv cov kev tsis txaus ntseeg, tab sis nws tsis yooj yim li Rockwell txoj kev. Vickers txoj kev tsis tshua siv nyob rau hauv cov qauv steel yeeb nkab. Hardness testing Annealed stainless hlau kav nrog ib txoj kab uas hla ntawm 6.0mm los yog ntau tshaj thiab phab ntsa thickness ntawm 13mm los yog tsawg dua tuaj yeem siv W-B75 Webster Hardness Tester, uas yog ceev heev thiab yooj yim rau kev sim, thiab yog tsim rau ceev thiab tsis- kev puas tsuaj tsim nyog tshuaj xyuas cov kav hlau stainless. .
