Khoom siv: Caij nplooj ntoos hlav steel (65Mn, 60Si2Mna), stainless hlau (304316L), stainless hlau (420)
Unit: txhiab daim
Hardness: HRC: 44-51, HY: 435-530
Kev kho deg: Blackening
Khoom siv: Manganese steel (65Mn, 1566)
Cov yam ntxwv ntawm cov khoom siv: Nws yog siv dav siv carbon caij nplooj ntoos hlav steel, uas muaj zog dua, hardness, elasticity, thiab hardenability piv rau 65 steel. Qhov tseem ceeb hardenability txoj kab uas hla yog feem ntau 30-50mm hauv dej thiab 16-32mm hauv roj. Nws muaj rhiab heev rau overheating thiab ib tug nyiam temper brittleness thaum tshav kub kub kho, thiab nws yog feem ntau tawg thaum lub sij hawm dej quenching. Roj quenching feem ntau yog siv. Dej quenching yog tsim rau seem qhov ntau thiab tsawg dua 80. Roj txias: Tom qab annealing, lub peev xwm txiav tau zoo, tab sis qhov txias deformation plasticity tsawg, thiab vuam kev ua haujlwm tsis zoo. Cov hlau no feem ntau yog siv tom qab quenching thiab tempering ntawm nruab nrab kub. 3-16
