304 stainless steel density 7.93 g / cm3 austenitic stainless steel are generally used this value 304 chromium content (%) 17.00-19.00, nickel content (%) 8.00-10.00,304 equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel

304 stainless steel is a versatile stainless steel, rust-proof performance than the 200 series of stainless steel stronger. High temperature is also better.

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

Of the oxidizing acid, in the experiment concluded that: concentration ≤ 65% of nitric acid below the boiling temperature, 304 stainless steel has a strong corrosion resistance. Alkali solution and most organic acids and inorganic acids also have good corrosion resistance.

General characteristics

304 stainless steel surface appearance and the possibility of diversification

Good corrosion resistance, durable than ordinary steel

Good corrosion resistance

High strength, so the possibility of using a large sheet

High temperature oxidation and high strength, it can resist fire

Room temperature processing, that is easy plastic processing

Because it does not need surface treatment, it is simple and easy to maintain

Clean, high finish

Good welding performance
