Stainless Steel 321 Pipe
The 321 Stainless Steel Seamless Tubing is produced without any welds or joints. They are manufactured using single-piece steel. This is why they are a little expensive compared to other pipes. The SS 321 Seamless Pipe is very strong and durable. These pipes can suffice in temperatures of 800-1500 degrees C. They are widely used in boilers, jet engines, exhausts, etc. The 321 SS Welded Pipe is completely free of post-welding carburization or pitting due to the excellent resistance from this grade. Apart from that, these pipes also possess excellent creep resistance.

For structural purposes and maintenance the w.nr. 1.4541 Square Pipe is used in many applications. These pipes have a modulus of elasticity in the tension of 193 Gpa. The pipe can also be easily fitted in inaccessible spots. The SS grade 1.4541 Polished Pipe is produced after the cold-rolling process. These pipes can be annealed or polished internally as well as externally depending on various parameters.
