Corrosion Resistance of Stainless Steel 304 Pipes

Stainless steel 304 pipes is a kind of high-strength steel that can resist corrosion in the air or in chemical corrosive media. It has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as plating, but plays the inherent surface properties of stainless steel. It is a kind of steel used in many fields.


1. Corrosion resistance of stainless steel 304 pipes


Stainless steel 304 pipes are commonly referred to as stainless steel. High-alloy steels such as 13 chrome steel and 18-8 chrome-nickel steel represent performance. From a metallographic point of view, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen from the intrusion of the steel and acts as a corrosion resistance. Although in order to maintain the inherent corrosion resistance of stainless steel 304 pipes, the steel must be contained more than 12% chromium.


304 is a versatile stainless steel, which is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). Stainless steel 304 pipes have excellent corrosion resistance and appearance.


2. Applications of stainless steel 304 pipes


In recent years, 304 stainless steel pipe tubing have been widely used in food, chemical, paper industry, atomic power generation, shipbuilding (chemical tanker) and other equipment, as well as piping, parts, etc., and they have a wide range of uses. The dirt, rust spots and weld marks caused by welding of these stainless steel materials during electric welding, cutting, bending and welding, not only affect the appearance, but also increase corrosiveness.


Generally, fluorine nitric acid is used as a pickling agent for cleaning. After cleaning, the surface of stainless steel will produce uneven black and spots. Because pickling is the final step of stainless steel processing products. Therefore, the pros and cons of pickling agents are related to the added value of the processed product itself. Therefore, some recent stainless steel processing industries require easy operation and balanced surface treatment, and 304 stainless steel tubes must not damage the surface of the stainless steel pickling agent.
