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.
