*at times,alloy 304L may show a lower corrosion rate than the higher carbon alloy 304,otherwise the 304,304L and 304H maybe considered to perform uniformly in most corrosive environment *Alloy 304L is preferred for use in environments sufficiently corr0sive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys.
304 stainless steel sheet 304 stainless steel, also known as 18/8 stainless steel, European norm 1.4301, is the most common stainless steel. The steel contains both chromium (usually 18%) and nickel (usually 8%) metals as the main non-iron constituents.
