Corten A steel plate and Corten B steel plate are both Atmospheric anti-corrosion steel materials which is widely used in deep ocean,wet and acid weather.We always call these two grades as Corten plate or weathering plate which can prevent corrosion by adding Cu% and Cr% in corten steel chemical composition.
What is different between Corten A steel plate and Corten B steel plate ? Corten A steel plate is normal used than corten B steel plate in ocean surroundings because corten A shall be done low temperature impacting test at -20 ℃,but corten b no need.In chemical composition,corten b plate requires more resitriction on P% than corten a plate.
