Hardness Test ntawm Stainless hlau kav

Annealed stainless hlau kav nrog ib txoj kab uas hla ntawm 6. -Txoj kev tsim nyog tshuaj xyuas cov kav dej stainless hlau. Cov kav hlau tsis muaj steel nrog lub taub sab hauv siab dua 30mm thiab phab ntsa thickness ntau dua 1.2 hli yuav tsum tau sim rau HRB thiab HRC hardness siv Rockwell hardness tester. Stainless hlau kav nrog ib txoj kab uas hla loj dua 30 hli thiab phab ntsa thickness tsawg dua 1.2 hli yuav tsum tau kuaj HRT los yog HRN hardness siv lub nto Rockwell hardness tester. Stainless hlau kav nrog ib txoj kab uas hla sab hauv tsawg dua 0mm thiab ntau dua 4.8mm yog kuaj rau HR15T hardness siv lub Rockwell hardness tester tshwj xeeb rau cov kav dej. Thaum lub puab txoj kab uas hla ntawm stainless hlau kav yog ntau tshaj 26 hli, Rockwell los yog nto Rockwell hardness testers kuj siv tau los ntsuam xyuas qhov hardness ntawm lub puab phab ntsa ntawm cov yeeb nkab.
