Stainless Seamless Yeeb Nkab
Hardness:
Stainless hlau raj feem ntau siv los ntsuas qhov hardness ntawm Brinell, Rockwell thiab Vickers.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 ob qho tib si intuitive thiab yooj yim.Txawm li cas los xij, nws tsis haum rau cov kav hlau steel ntawm cov tawv tawv lossis nyias nyias.
Rockwell hardness:
Stainless hlau raj Rockwell hardness test yog tib yam li Brinell hardness test.Qhov txawv yog tias nws ntsuas qhov tob ntawm qhov indentation.Rockwell hardness test yog ib txoj hauv kev uas HRC siv ob tsuas yog Brinell hardness HB hauv cov qauv steel yeeb nkab.Rockwell hardness tuaj yeem siv rau kev txiav txim siab ntawm cov khoom siv hlau los ntawm qhov muag heev mus rau qhov nyuaj heev.Nws them nyiaj rau Brinell txoj kev.Nws yog qhov yooj yim dua li Brinell txoj kev thiab tuaj yeem nyeem ncaj qha tus nqi hardness 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
Stainless hlau raj Vickers hardness test kuj yog ib qho kev ntsuas indentation rau ntsuas cov ntaub ntawv nyias nyias thiab txheej txheej hardness.Nws muaj qhov zoo ntawm Brinell thiab Rockwell txoj hauv kev, thiab kov yeej lawv qhov tsis txaus, tab sis nws tsis yooj yim li Rockwell txoj kev.Txoj kev Vickers tsis tshua siv nyob rau hauv cov qauv yeeb nkab steel.
Kev kuaj Hardness
Stainless hlau raj muaj ib txoj kab uas hla ntawm 6.0mm los yog ntau tshaj thiab ib tug annealed stainless hlau raj nrog ib tug phab ntsa thickness ntawm 13mm los yog tsawg dua.Nws tuaj yeem yog W-B75 hom Vickers hardness tester.Nws yog qhov nrawm heev thiab yooj yim rau kev sim thiab tsim nyog rau kev soj ntsuam sai thiab tsis muaj kev puas tsuaj ntawm cov kav hlau stainless.Stainless hlau raj nrog ib txoj kab uas hla ntawm ntau tshaj 30 hli thiab phab ntsa thickness ntau tshaj 1.2 hli yog kuaj nrog ib tug Rockwell hardness tester los kuaj HRB thiab HRC hardness.Stainless hlau raj nrog ib txoj kab uas hla ntawm ntau tshaj 30 hli thiab phab ntsa thickness tsawg tshaj li 1.2 hli yog kuaj nrog ib tug nto Rockwell hardness tester kuaj HRT los yog HRN hardness.Rau cov kav hlau tsis muaj steel nrog lub taub sab hauv ntawm tsawg dua 0 hli thiab siab dua 4.8 hli, qhov nyuaj ntawm HR15T yog kuaj los ntawm Rockwell hardness tester tshwj xeeb rau cov kav dej.Thaum lub puab txoj kab uas hla ntawm stainless hlau raj yog loj dua 26 hli, lub hardness ntawm lub puab phab ntsa ntawm lub raj kuj yuav raug kuaj los ntawm ib tug Ro.
