303 vs. 304 stainless steel: what's the difference? | Essentra
In general, 304 is stronger than 303 stainless steel. 304 stainless steel contains a higher percentage of chromium (18-20%) and nickel (8-10.5%) than 303 stainless steel, which not only gives it superior corrosion resistance, but higher strength. While 303 stainless steel has slightly higher ultimate tensile strength (UTS) and yield strength ...
