S235J0W thiab S235J2W yog ob qho tib si European tus qauv (EN 10025-5) weathering (Corten) steels, muab kev txhim kho atmospheric corrosion kuj, zoo tagnrho rau cov choj, facades, thiab tsheb tsim yam tsis xav tau kev tiv thaiv nto. Qhov sib txawv tseem ceeb yog nyob rau hauv lawv qhov kev ntsuam xyuas qhov hnyav, nrog S235J0W xav tau Charpy V-qhov cuam tshuam ntawm lub zog ntawm 0 degree, thaum S235J2W xav kom nws ntawm -20 degree, qhia tias J2W muaj kev ua haujlwm kub qis dua rau cov qauv ruaj khov, ruaj khov.
