P355GH thiab S355J2 (feem ntau ua ke nrog P355J2) yog siab- lub zog, weldable steels, tab sis txawv hauv daim ntawv thov: P355GH (EN 10028-2) yog lub siab hlab ntsha hlau tsim los rau qhov kub siab, siv hauv boilers thiab petrochemicals peb, nrog zoo yas. S355J2 (EN 10025-2) yog cov qauv hlau paub txog lub zog zoo thiab qis- qhov kub thiab txias (txog -20 degree), zoo tagnrho rau kev tsim kho, txuas hniav, thiab cov cheeb tsam txias, muaj qhov zoo weldability thiab cuam tshuam tsis kam. Ob leeg muaj lub zog zoo heev (nyob ib puag ncig 355 MPa tawm los), tab sis lawv cov 'G' (kub-resistant) vs 'J2' (tseem ceeb cuam tshuam) txhais tau tias lawv siv thawj.
P355GH (Lub Nkoj Siab)
Txheem: EN 10028-2
Cov yam ntxwv tseem ceeb: Tsim los rau siab - kev pabcuam kub (piv txwv li, hauv boilers, chav nruas).
Khoom: Zoo plasticity, toughness, txias dabtsi yog khoov, thiab vuam kev ua tau zoo.
Daim ntawv thov: boilers, siab hlab ntsha, petrochemical khoom.
S355J2 (Structural)
Txheem: EN 10025-2 (Ceeb toom: feem ntau siv raws li S355J2)
Cov yam ntxwv tseem ceeb: Zoo heev qis- qhov kub thiab txias cuam tshuam (Charpy-V ntsuas ntawm -20℃).
Khoom: nruab nrab tensile lub zog, yooj yim weldable, zoo dav toughness.
Daim Ntawv Thov: Kev tsim kho, txuas hniav, txias-cov haujlwm hauv cheeb tsam, kev tsim vaj tsev dav dav.
Qhov Tseem Ceeb Qhov Sib Txawv Zoo Tshaj
Kub: P355GH excels nyob rau hauv kub kub; S355J2 ua tau zoo nyob rau hauv txias txias.
Txuj: Txawv European qauv (EN 10028-2 vs. EN 10025-2).
Kev Siv Tseem Ceeb: P355GH rau siab / cua sov; S355J2 rau cov qauv dav dav / txias.
