Kev ua tau zoo ntawm Q690D siab zog steel phaj

Kev ua tau zoo ntawm Q690D siab zog steel phaj

Koj puas tau saib ntu kawg?Niaj hnub no, tus editor yuav qhia rau koj ib tug steel phaj uas yog ib theem siab tshaj Q550D: Q690D.
Q690D belongs rau high-strength welded qauv steel.Ntawm lawv, Q yog sawv cev rau lub zog tawm los, 690 sawv cev rau cov nqi zog, thiab D sawv cev rau qib ntawm cov phaj steel.
1. Kev xa khoom raws li txoj cai
Feem ntau xa hauv kub-dov, quenched thiab tempered xeev;
2. Cov lus qhia tshwj xeeb
Lub thickness yog 8-120mm, qhov dav yog feem ntau 2200 thiab 2500mm, thiab qhov ntev yog 12000mm;
(Kom kawm paub ntxiv txog qhov cuam tshuam ntawm cov khoom steel tshwj xeeb, xws liMn13 Hnav Resistant Hlau Phaj, koj tuaj yeem tiv tauj peb)
3. Cov yam ntxwv ua tau zoo
Q690D tuaj yeem raug hu ua qhov kub tsis tshua muaj zog hlau nrog lub zog tawm ntawm 690Mpa.Q690D steel phaj muaj ntau dua yield zog thiab tensile zog.Mechanical zog yog raws li nram no:
Tawm lub zog: ≥690Mpa;
Tensile zog: 770-940Mpa;
Elongation A%: ≥14;
Kev poob siab kub: -20 ° C;
Lub zog cuam tshuam: ≥27 J;
