Hardness Test ntawm Stainless hlau kav

Annealed stainless hlau yeeb nkab nrog rau sab hauv txoj kab uas hla saum 6. cev steel. Stainless hlau yeeb nkab nrog lub taub sab hauv siab dua 30mm thiab phab ntsa thickness ntau dua 1.2 hli yog kuaj los ntawm Rockwell hardness tester los kuaj HRB thiab HRC hardness. Stainless hlau yeeb nkab nrog lub taub sab hauv siab dua 30 hli thiab phab ntsa thickness tsawg dua 1.2 hli yog kuaj HRT los yog HRN hardness los ntawm kev siv nto Rockwell hardness tester. Rau cov kav hlau tsis muaj steel nrog lub taub sab hauv tsawg dua 0mm thiab ntau dua 4.8mm, Rockwell hardness tester rau cov kav dej yog siv los ntsuas HR15T hardness. Thaum txoj kab uas hla ntawm cov yeeb nkab steel hlau tsis ntau tshaj 26 hli, qhov hardness ntawm sab hauv phab ntsa ntawm cov yeeb nkab kuj tuaj yeem kuaj nrog Rockwell lossis nto Rockwell hardness tester.
