Stainless Steel Seamless Tube and ASTM A269 Welded Tubing

Check Stainless Steel Tube Weight Chart, Supplier of Stainless Steel Tube

Stainless Steel Tube is a type of steel tube made up of stainless steel material. There are different materials that are called stainless steels. Each kind has its own specification and standards, chemical composition and physical attributes and mechanical properties as well. Roopam Steel is a supplier of stainless steel tubes in different forms, shapes and grades. The austenitic stainless steels are the most used of all stainless steels and the 304 grade is the most used of all the stainless steel grades. There are Stainless Steel Seamless Tube types that are made through a process which makes them seamless. The tubes have less absolute roughness, meaning, the surface is smoother. The Stainless Steel Tube & SS Seamless Tubing is good for instrumentation and in high precision applications because the diameter of the tubes is precise throughout the length.

The Stainless Steel Welded Tube is stronger but has seam, or the track of welding on it. The welded tubes are also dimensionally less accurate than the seamless tubes. These can be used as Stainless Steel Mechanical Tubing in applications where high mechanical properties are required. The 316 is a reasonably corrosion resistant austenitic stainless steel that can be used in most applications. There are other categories such as ferritic, martensitic and duplex stainless steels. Roopam Steel is stainless steel tube manufacturer in india, We have huge stock of Stainless Steel Round Tube due to which we are leading stainless steel tubing supplier in Mumbai. Some are used as Stainless Steel Sanitary Tubing. There are different specifications to nominate different properties. For example, the ASTM A269 Welded Tube includes grades 304, 304L, 316 and 316L with the diameters ranging from 1/8 inches to 24 inches. Please contact us for any clarifications or order.
