304 and 316 Stainless Steel Box Pipe Exporter in Kolkata

SS 304 Square Pipe is one of the grades of square pipes made from stainless steels. There are austenitic, ferritic and martensitic stainless steel grades, each with different compositions and mechanical properties. There are also alloy steels and others such as the Astm A554 Square Tube. The SS square pipes are light weight and can be used in applications that required low weight. The SA554 SS square pipes can also be highly corrosion resistant and are used in structural applications such as building up airplane frames and in decorative applications as well. We are renowned Stainless Steel Square Pipe Supplier In India. The 304 pipes are the most used of square pipes. The square pipes have a geometric strength added to the material strength. The 304 SS Box Pipe has good corrosion resistance in addition to the strength.

The 316 material has molybdenum in the composition which makes it resistant to sea water, brackish water and chloride ion rich environments. There are other materials than the stainless steel which are used for making the square pipes. The different grades of stainless steel square pipe are used in different applications. These could be used in water lines, structural elements and other specific applications. Sometimes, the square pipes need extra corrosion resistance and come with galvanization. The 316 Stainless Steel Box Pipe is used in outdoor applications, structures and in some framework building due to the strength and galvanized, increased corrosion resistance.
