Stainless hlau yeeb nkab yog ib hom hollow ntev puag ncig steel, uas yog tsuas yog siv dav hauv cov kav xa hluav taws xob thiab cov khoom siv kho tshuab xws li roj av, tshuaj lom neeg kev lag luam, kev kho mob, khoom noj khoom haus, lub teeb kev lag luam, kev siv tshuab, thiab lwm yam. Tsis tas li ntawd, thaum lub dabtsi yog khoov thiab torsional lub zog yog tib yam, qhov hnyav yog sib dua, yog li nws kuj tau siv dav hauv kev tsim cov khoom siv kho tshuab thiab cov qauv engineering.
Ntawm cov qauv stainless hlau yeeb nkab, Brinell hardness yog feem ntau siv. Indentation txoj kab uas hla feem ntau yog siv los qhia cov hardness ntawm cov khoom, uas yog ob qho tib si intuitive thiab yooj yim. Tab sis nws tsis haum rau cov kav hlau uas ua los ntawm cov tawv tawv los yog nyias nyias.
Rockwell hardness test ntawm stainless hlau yeeb nkab yog tib yam li Brinell hardness test, uas yog ib qho kev xeem indentation. 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 yog siv nyob rau hauv steel yeeb nkab qauv thib ob tsuas yog Brinell hardness HB. Rockwell hardness tuaj yeem siv los ntsuas cov ntaub ntawv hlau los ntawm cov mos mos mus rau qhov nyuaj heev. Nws ua rau qhov tsis txaus ntawm Brinell txoj kev. Nws yog qhov yooj yim dua li Brinell txoj kev thiab 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 test ntawm stainless hlau yeeb nkab kuj yog ib qho kev xeem indentation txoj kev 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 hauv kev thiab kov yeej lawv qhov tsis txaus ntseeg, tab sis nws tsis yooj yim li Rockwell txoj kev. Vickers txoj kev yog tsis tshua muaj siv nyob rau hauv steel yeeb nkab qauv.
Folding hardness kuaj
Rau annealed stainless hlau kav uas muaj ib txoj kab uas hla ntawm ntau tshaj 6. Qhov kev ntsuam xyuas yog nrawm heev thiab yooj yim, thiab tsim nyog rau kev soj ntsuam sai thiab tsis muaj kev puas tsuaj ntawm cov kav hlau stainless. Rau cov kav hlau tsis muaj steel nrog lub taub sab hauv siab dua 30mm thiab phab ntsa tuab dua 1.2mm, siv Rockwell hardness tester los ntsuas HRB thiab HRC hardness. Rau cov kav hlau tsis muaj steel nrog ib txoj kab uas hla ntau dua 30mm thiab phab ntsa thickness tsawg dua 1.2mm, siv lub ntsej muag Rockwell hardness tester los kuaj HRT lossis HRN hardness. Rau cov kav hlau tsis muaj steel nrog lub taub sab hauv tsawg dua 0mm thiab ntau dua 4.8mm, siv lub Rockwell hardness tester tshwj xeeb rau cov kav dej los ntsuas HR15T hardness. Thaum lub puab txoj kab uas hla ntawm stainless hlau yeeb nkab yog ntau tshaj 26 hli, lub hardness ntawm lub puab phab ntsa ntawm cov yeeb nkab kuj yuav raug kuaj nrog ib tug Rockwell los yog nto Rockwell hardness tester.
