The material of Aohea stainless steel bento lunch box
304 stainless steel is a universal stainless steel material, and its anti-rust performance is stronger than that of 200 series stainless steel materials. High temperature resistance is also better, as high as 1000-1200 degrees. 304 stainless steel has excellent stainless corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration ≤ 65% below the boiling temperature. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
