s355j2wp vs s355j0wp wb
S355J2WP vs. S355J0WP yog ob qho tib si atmospheric corrosion-resistant (weathering) steels raws li EN 10025-5, tab sis qhov sib txawv tseem ceeb nyob hauv lawvtshuaj muaj pes tsawg leeg, tshwj xeeb yog Phosphorus (P) cov ntsiab lus, nrogS355J2WP feem ntau muaj P siab dua rau kev txhim kho corrosion kuj, thaumJ0 muaj qis dua P, nrog rau ob qho tib si ntsib lub zog zoo sib xws (355 MPa yield) thiab cov kev xav tau ntawm cov tawv nqaij (J0 yog 0 degree, J2 yog -20 degree), txawm hais tias 'W' qhia txog huab cua thiab 'P' qhia ntxiv phosphorus kom zoo dua xeb patina tsim.
Ntawm no yog ib qho kev sib cais:
S355:Yam tsawg kawg nkaus yield zog ntawm 355 MPa (rau thicknesses txog 16 hli).
J0 / J2:Qhia txog qib toughness; J0 yuav tsum muaj kev cuam tshuam lub zog ntawm 0 degree, J2 ntawm -20℃(J2 yog tawv dua).
W:Txhais tau hais tias nws yog ib tug weathering hlau nrog txhim kho atmospheric corrosion kuj (Corten steel).
P:Qhia ntxiv Phosphorus (P) rau cov xeb xeb zoo dua, ua rau huab cua ntau dua - tiv taus ntau dua li qib tsis muaj 'P' (xws li S355J2W).
Qhov txawv tseem ceeb:
S355J0WP:Muaj tsawg Phosphorus (P), tso siab ntau rau Cu, Cr, Ni rau corrosion kuj, feem ntau xa tuaj.
S355J2WP:Muaj cov ntsiab lus phosphorus (P) ntau dua, uas ua rau nws tus kheej - tiv thaiv patina tsim, muab kev tiv thaiv corrosion zoo tshaj rau kev siv sab nraum zoov.
Hauv qab no yog lawv qhov kev sib piv ntawm cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab kev cuam tshuam kev kuaj lub zog.
