In food machinery SUS304 used less frequently, so it is a kind of material?

SUS is Japan material standard, 304 stainless steel in accordance with United States ASTM standards produce a grade of stainless steel. 304 is equivalent to our 0Cr19Ni9 (0Cr18Ni9) stainless steel, Japan also references the United States called, known as: SUS304.

SUS304 stainless steel is the most widely used a chromium-nickel stainless steel, rust-proof performance stronger than the 200 series stainless steel material. Has good corrosion resistance, heat resistance, strength and mechanical properties at low temperature. In the experiment concluded that nitrate concentrations below the boiling temperature of ≤ 65%, 304 stainless steel is highly resistant to corrosion. If it's heavy pollution in the industrial area, you will need to clean in order to avoid corrosion. Particularly suitable for the processing, storage and transportation of food. Has a good workability and weldability. 304 stainless steel is State-approved food-grade stainless steel.

SUS304 high temperature resistance are also good. Stainless 304 stainless steel with excellent resistance to corrosion and good resistance to intergranular corrosion. Oxidizing acids, obtained in the experiments: the concentration of nitric acid below the boiling temperature of ≤ 65%, 304 stainless steel is highly resistant to corrosion. Alkaline solutions, and most organic acids and inorganic acids has a good resistance to corrosion.

Through the introduction of simple, everyone an idea about food machinery and materials, so that in future food machinery purchase could be aware.
