Kev nyuaj
Stainless hlau kav feem ntau ntsuas los ntawm peb lub hardness ntsuas: brinell, rockwell thiab vickers .
Brinell hardness
Nyob rau hauv cov stainless hlau yeeb nkab txheem qauv, tawv tawv yog feem ntau siv cov khoom siv hlau, nws tsis yog siv rau cov kav hlau ua kom nyuaj lossis nws tsis yooj yim, nws tsis yog qhov nyuaj rau cov tawv hlau lossis nws tsis yooj yim
Rockwell Hardness
Lub rockwell hardness ntsuas ntawm cov kav hlau stainless hlau yog tam sim no HB sib txawv yog tam sim no ntawm kev siv cov qauv yeeb nkab hardness tuaj yeem siv los ntsuas cov ntaub ntawv hlau los ntawm cov qauv Brinell {} Nws ua rau muaj nuj nqis rau kev hu ua tus nqi Brinell, tsis yog qhov tseeb yog li tus qauv Brinell {}}
Vickers hardness
Lub Vickers Kev Ntsuas Cov Khoom Siv Tsis Muaj Khoom Tseem Ceeb ntawm cov qauv hluav taws xob, thiab cov qauv hluav taws xob tsis zoo, tab sis nws muaj cov qauv sib txuas, thiab cov qauv siv hluav taws xob tsis tshua tau siv rau hauv cov hlau yeeb nkab
Kev ntsuas hardness
Annealed Stainless Hlau Kav Nrog ib lub taub hau sab hauv ntau dua li 6mm tuaj yeem kuaj nrog kev ua kom nrawm dua li 13mm tuaj yeem sim ua kom nrawm dua li 13,4 8}} 30mm and a wall thickness greater than 1.2mm are tested with Rockwell hardness tester for HRB and HRC hardness. Stainless steel pipes with an inner diameter greater than 30mm and a wall thickness less than 1.2mm are tested with surface Rockwell hardness tester for HRT or HRN hardness. Stainless hlau kav nrog lub taub sab hauv tsawg dua 08mm yog sim nrog HR15t hardness siv cov tshwj xeeb rockwell lub hardness tester rau kav dej. Thaum lub taub sab hauv ntawm cov yeeb nkab steel hlau loj dua 26mm, lub zog ntawm cov yeeb nkab sab hauv kuj tseem tuaj yeem kuaj nrog rockwell lossis nto Rockwell Hardness Hardness Tester.
