The composition of ASTM A890-4A steel is notable for including copper (Cu) and containing a comparatively high amount of chromium (Cr). Copper is primarily used to improve resistance to acids. Chromium is the defining alloying element of stainless steel. Higher chromium content imparts additional corrosion resistance.
