Q460E yog ib lub phaj hlau rau lub zog siab ua haujlwm tempering, tseem hu ua phaj siab zog thiab qis alloy siab zog phaj.
High zog phaj yog tus cwj pwm los ntawm lub zog siab thiab cov txiaj ntsig siab. Cov qib yog: Q390, Q420, Q460, Q500, Q550, Q690, thiab cov qib no.
Q460E yog tsim los ntawm 'Q' qhia los ntawm kev tawm los; 460 qhia tias tus nqi tawm los ntawm cov hlau phaj yog 460MPa; 'E' qhia txog cov phaj hlau rau qhov kev ntsuas cuam tshuam rau -40 degree (feem ntau siv qib C, D, E).
Q460E steel phaj siv tus qauv: (GB / T1591 lossis GB / T3274).
Q460E steel phaj cov khoom xa tuaj raws li txoj cai: tempered (quenched + tempered).
Q460E steel phaj tuaj yeem ua thickness kev coj ua haujlwm: Z15, Z25, Z35.
Q460E steel phaj flaw detection theem: 'ib sojntsuam, ob sojntsuam, peb sojntsuam'.
Q460E steel phaj ceev: 7.85 / cubic meter
Q460E mechanical properties: Q460E thickness ≤50 yield strength 460Mpa; tensile strength 550-720; Q460E thickness >50-100 yield strength 440Mpa; tensile strength 550-720; Q460E thickness >100-150 yield zog 400Mpa; tensile zog 500-670; Q460E steel phaj elongation ntawm tawg 17%;
Q460E yog dav siv nyob rau hauv txhua yam ntawm engineering machinery, xws li mining thiab txhua yam engineering siv nrog drilling rigs, hluav taws xob shovels, hluav taws xob log pob tseg tsheb, tsuas tsheb, excavators, loaders, bulldozers, txhua yam cranes, thee mine hydraulic txhawb thiab lwm yam.
