What is Annealed Pickled Surface?
The surface pickling process of stainless steel pipes involves treating the surface with an acidic solution, such as sulfuric or hydrochloric acid, to remove impurities like oxides, oil residue, and welding scales. This method cleanses the surface, eliminating oxide layers and providing a cleaner and smoother appearance to the stainless steel surface. This treatment enhances the corrosion resistance of the pipes and makes them more suitable for various applications, such as in chemical industries and oil processing. The pickled surface of stainless steel pipes typically exhibits increased luster, improving both the quality and appearance of the pipes.
What is the advantage of stainless steel?
Stainless Steel is a high alloy steel that resists corrosion. It has a beautiful surface and does not need to undergo surface treatment such as color plating or painting.
The most basic characteristic of stainless steel is its resistance to rust under atmospheric conditions and corrosion in various liquid media. This characteristic has a direct relationship with the chromium content in steel, the presence of chromium makes the steel surface to generate a layer of invisible film, which can prevent oxidation, so that the material "passivation" or corrosion resistance. The addition of other elements such as nickel or molybdenum increases corrosion resistance, strength and temperature resistance. MTSCO has been engaged in the supply of industrial piping products for 17 years, and can provide all kinds of piping products and fittings made of stainless steel, such as austenitic 300 series, duplex steel, ferrite 400 series and so on.
