Khoom siv: Caij nplooj ntoos hlav hlau (65mn, 60Si2MNA), Stainless Hlau (304316L), Stainless Hlau (420)

Chav: txhiab daim

Hardness: HRC: 44-51, HY: 435-530

Nto Kho: Blackening

Cov Khoom Siv: Manganese Hlau (65mn, 1566)

Cov yam ntxwv cov khoom siv: Nws yog cov khoom siv caij nplooj ntoos hlav steel hlau, uas muaj lub zog tshiab, tawv tawv, elasticity, thiab kev nyuaj piv rau 65 steel. Qhov tseem ceeb tawv tawv ntawm txoj kab uas feem ntau muaj 30-50mm hauv dej thiab 16-32 hli nyob rau hauv cov roj. Nws muaj qhov rhiab heev rau kev kub ntxhov thiab kev sim siab brittleness thaum kho cua sov, thiab yog tus nquag tawg thaum lub sijhawm quenching. Roj quenching feem ntau siv. Dej quenching yog haum rau seem ntau tshaj 80. Roj txias deformation: tab sis qhov kev sib tw txias yog tsawg, thiab kev ua haujlwm vuam yog neeg pluag. Cov hlau no feem ntau siv tom qab quenching thiab tempering ntawm nruab nrab kub. 3-16
