Kencotube is among the top most manufacturer & dealer in SS 321 Pipes & Tubes, which are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 Degree C. A limitation with SS 321 Tubes is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. Stainless Steel 321 Tubes is used for functions in the temp range of approximately 900 Degree C, uniting soaring potency, phase stability and resistance to scaling by means of resistance to succeeding aqueous corrosion. Like other austenitic grades, Alloy 321 Pipes Tubes have excellent forming and welding characteristics, are readily brake or roll formed and have outstanding welding characteristics.
Post-weld annealing is not required, where 321 Stainless Steel Pipes Tubes is a heat resistant, titanium stabilized, austenitic alloy that's commonly used for service in the 1000 Degree F – 1600 Degree F temperature range. Grade 321 Pipes Tubes is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800 Degree -1500 Degree F. Stainless Steel 321 Seamless Pipes is similar to SS 304 but with titanium addition of at least five times the carbon content. This titanium addition in Stainless Steel 321 Welded Pipes reduces or prevents carbide precipitation during welding. We also offer these products in different sizes and shapes as per clients’ requirements.
