HSS Round Bar Khoom Taw Qhia
M42 ultra-siab ceev steel yog ib qho zoo cobalt high-speed steel nrog cobalt ntsiab lus ntawm 8% los yog 10%, thiab nws cov tshuaj muaj pes tsawg leeg muab siab hardness thiab zoo heev kub hardness. Cov khoom no ua rau M42 yog qhov kev xaiv zoo tshaj plaws rau kev siv lub zog siab steels, pre-hardened steels, high-hardness alloys thiab nyuaj-rau-machine non-ferrous superalloys siv nyob rau hauv aerospace, roj av thiab lub zog tsim kev lag luam.
Qhov no M42 high-speed steel bar Tshuag ua rau cov cuab yeej ua tiav kev ua tau zoo heev. Nws muaj lub siab hardness thiab zoo heev thermal hardness thiab paub txog nws zoo heev hnav tsis kam.
Tsis tas li ntawd, M42 muaj kev kho cua sov siab hardness (68 mus rau 70 HRC) thiab nthuav tawm kev hnav zoo heev. Yog li ntawd, nws yog dav siv nyob rau hauv hlau manufacturing kev lag luam.
