AISI ASTM Round Decor Seamless Welded SS Tubes Pipes 316 316L 310S 321 201 304 Stainless Steel Tube Pipe
The main issue with welding stainless steel alloy is that they are susceptible to intergranular corrosion. However, the exception for such conditions is the use of heat resisting steels such as Stainless Steel 321 Seamless Pipe. An austenitic alloy, grade 321 is stainless steel that is stabilized by the inclusion of titanium in its chemistry. Unlike other stainless steels that contain higher amounts of carbon in their alloy, titanium is added to the alloy of Stainless Steel 321 Pipe, which prevents the formation of carbide precipitates. The formation of carbide precipitates is common between a temperature range of 427°C – 816°C. At elevated temperatures such as this, the carbon present in steels like 304 or 316 together with chromium reacts with the atmospheric oxygen, thus forming precipitates.
