The 304 stainless steel square rod is a versatile stainless steel material with stronger rust resistance than the 200 series stainless steel. High temperature resistance is also good, the general use temperature limit is less than 650 °C.

304 stainless steel has excellent stainless corrosion resistance and good resistance to intergranular corrosion.

For oxidizing acids, it is found in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid below the boiling temperature of ≤ 65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
