Stainless steel square tube

Stainless steel square tube is a hollow long steel strip, because the cross section is square so it is called square tube. It is widely used as a pipeline for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. Classification of stainless steel square tube: Square tube is divided into two categories: seamless steel tube and welded steel tube (seam tube). According to the cross-sectional shape, it can be divided into square and rectangular tubes.

The characteristics of stainless steel square tubes mainly include the following aspects:

Corrosion resistance: Stainless steel square tubes are made of high-quality stainless steel materials and can be used for a long time in various corrosive environments.

High strength: Stainless steel square tubes have good strength and toughness and can withstand certain external loads.

High temperature resistance: Stainless steel square tubes can work in high temperature environments without deformation or oxidation.

Aesthetics: The surface of stainless steel square tubes is smooth and has no obvious defects, which is suitable for occasions that require a fine appearance.

Easy processing: Stainless steel square tubes have good processability and are easy to cut, weld and install.

Wear resistance: Stainless steel square tubes are not only corrosion-resistant and high-strength, but also wear-resistant and easy to clean. In some occasions that require frequent cleaning and disinfection, equipment, utensils, auxiliary accessories, etc. made of stainless steel square tubes have good cleaning performance, which can effectively prevent the reproduction and spread of microorganisms and meet the requirements of relevant health regulations.

Composition of Stainless Steel

 

Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and

mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
