Lub zog muaj zog, elastic thiab high-txiav kev ua tau zoo caij nplooj ntoos hlav steel raw khoom, tus yam ntxwv los ntawm cov saum toj no-hais lub caij nplooj ntoos hlav steel raw khoom nrog ib tug luj piv ntawm 0.48% ~ 0.55% C , 0.17% ~ 0.37% Si, 0.70% ~ 1.00% Mn, 0.8% ~ 1.10% Cr, 0.001% ~ 0.004% B, Tsawg dua los yog Sib npaug 0.35% Ni, Tsawg dua lossis sib npaug 0.25% Cu, Tsawg dua lossis sib npaug 0.03% P, Tsawg dua lossis sib npaug 0.03% S, thiab lwm yam yog Fe.
Qhov no hemiplegic steel yog lub zog siab, elastic thiab high-txiav caij nplooj ntoos hlav steel raw khoom nrog muaj zog elasticity thiab siab txiav kev ua haujlwm nrog 50CrVA thiab kev ua haujlwm siab heev nrog kev txiav siab heev thiab kev ua haujlwm siab ntawm tus nqi siab heev.
Txhawm rau ua kom muaj kev ua haujlwm zoo rau cov khoom siv raw ntawm GB1222-92 caij nplooj ntoos hlav steel ntawm theem no. Nws yog tsim rau zus tau tej cov steel raw cov ntaub ntawv rau zus tau tej cov elastic ntsiab nrog loj cross-section thiab siab zog elasticity, thiab yog heev haum rau zus tau tej cov steel raw cov ntaub ntawv rau zus tau tej cov nplooj springs nrog ib tug tuab ntawm ntau dua los yog sib npaug li 20mm thiab tsawg dua lossis sib npaug ntawm 36mm. Piv nrog rau cov cuab yeej siv tam sim no, cov khoom no muaj ntau yam zoo xws li kev txhim kho kev lag luam muaj pes tsawg leeg, daim ntawv thov dav dav, siab elasticity thiab kev ua haujlwm zoo.
