Kev ua tau zoo
Formulated nrog meej Molybdenum alloying (0.45% - 0.60%) kom xa mus ntev - lub sij hawm kev ruaj ntseg nyob rau hauv siab kub ib puag ncig mus txog ~ 480℃.
Tsim los ntawm LF + VD lub tshuab nqus tsev degassing cov txheej txheem kom tsis txhob muaj leej faj thiab phosphorus impurities, txo qhov tsis xws luag sab hauv kom siab - kev nyab xeeb siab.
Tsim los nrog kev tswj cov pa roj carbon sib npaug kom tswj tau qhov zoo ntawm weldability thiab txo cov kev xav tau ntawm preheating thaum lub sij hawm tsim cov hlab ntsha.
Ua kom tau raws li ASTM A204 / ASME SA204 specifications, muaj 100% ultrasonic kuaj raws li ASTM A578 lossis A435 qauv.
Muab lub zog ua haujlwm zoo ib yam thoob plaws Qib A, B, thiab C nrog lub zog tensile ntau yam kev xaiv los ntawm 450 MPa rau 655 MPa.
