304 stainless steel is a universal stainless steel material, and its rust resistance is stronger than that of 200 series stainless steel materials. High temperature resistance is also relatively good, can be as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. For oxidizing acids, it was found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of ≤65% below the boiling temperature. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
The price of 304 bright annealed seamless stainless steel pipe is about 200 yuan. (Prices are for reference only)
304 bright annealed seamless stainless steel pipe is steel that is not easy to rust. In fact, some stainless steels have both rust resistance and acid resistance (corrosion resistance). The rust and corrosion resistance of stainless steel is due to the formation of a chromium-rich oxide film (passivation film) on its surface. This rust resistance and corrosion resistance are relative. Tests show that the corrosion resistance of steel in weak media such as atmosphere and water and in oxidizing media such as nitric acid increases with the increase of chromium water content in steel. When the chromium content reaches a certain percentage, the corrosion resistance of steel occurs. Mutation, that is, from easy to rust to not easy to rust, from corrosion-resistant to corrosion-resistant.
