Qhov "L" hauv S690QL txhais tau tias qis dua- ntsuas qhov kub thiab txias (-40 degree) rau kev txhim kho huab cua txias.
Dab tsi yog daim ntawv thov kev lag luam ntawm S690Q?
S690Q yog lub siab- lub zog steel siv nyob rau hauv daim ntawv thov uas yuav tsum tau muaj zog zoo heev - rau - hnyav piv, xws li txuas hniav, cranes, offshore platforms, hnyav machinery, thiab siab - nce vaj tse, tso cai rau sib zog tsis tau robust tsim nyob rau hauv kev tsim kho thiab cov khoom siv, tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas muaj kev ntxhov siab thiab kev xav tau ntawm qhov kub thiab txias (xws li qhov kub thiab txias).
Dab tsi yog qhov muaj pes tsawg leeg ntawm S690Q?
S690Q yog lub siab -lub zog, qis- alloy steel (HSLA) txhais los ntawm EN 10025-6 tus qauv, paub txog nws 690 MPa yield zog tom qab quenching thiab tempering, featuring tswj qib ntawm carbon (Less dua los yog sib npaug rau 0.22% ntau dua), Silicon (Lession). tshaj los yog sib npaug rau 1.8%), nrog ntxiv dag zog rau microalloying ntsiab zoo li Niobium, Vanadium, Titanium, Chromium, Molybdenum, thiab Nickel, kom ntseeg tau zoo weldability rau hnyav-duty daim ntaub ntawv xws li txuas hniav, cranes, thiab cov khoom siv.
