Ob leeg S355J0WP steel thiab s355J2WP steel belongs rau European txheej txheem atmospheric corrosion resistant steel, uas muaj ib tug tiv thaiv xeb txheej tiv thaiv atmospheric corrosion. Ntxiv ib qho nyiaj ntawm cov ntsiab lus alloying, xws li P, Cu, Cr, Ni, Mo, rau cov hlau, txhawm rau ua kom muaj zog tiv thaiv huab cua corrosion, nyob rau hauv kev cuam tshuam ntawm huab cua, ib qho kev tiv thaiv tsis siv neeg oxide yog tsim los ntawm lub hauv paus hlau. S355J0WP steel thiab S355J2WP steel daim hlau thiab cov ntawv tuaj yeem siv los tsim cov khoom qis- alloy structural steel rau steel qauv xws li tsheb, txuas hniav, yees, thiab ntim.
Hauv qab no yog lawv qhov kev sib piv ntawm cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab cov kev ntsuam xyuas lub zog.
Cov tshuaj muaj pes tsawg leeg ntawm S355J0WP steel thiab S355J2WP phaj (kev tshuaj xyuas melting):
