Grade 321 is an austenitic alloy, which is stabilized with the help of titanium. The Stainless Steel 321 Pipe/ Tube provides excellent corrosion resistance properties and acts as a sterilizing agent. This grade was initially designed to combat intergranular corrosion, which the 304 grade was susceptible to in various ranges. The Stainless Steel 321 Pipe possesses excellent mechanical properties. These pipes have a density of 8027 gm/cm3 and can be elongated by 40% in various applications. With a melting point between 1398-1146 degrees C, the Stainless Steel 321 Tube is very durable in nature. These tubes have minimum yield strength of 205Mpa and tensile strength of a minimum of 515Mpa. The 321 Exhaust Tubing is extremely strong and doesn’t bend easily. These tubings have a hardness of 217 Brinell and can handle a lot of heat and smoke. We are the leading 321 Stainless Steel Tubing suppliers in Mumbai. We thrive to produce the best products, which are available to all at reasonable rates.
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. We are amongst the few 321 Stainless Steel Pipe suppliers in India who make use of the best products and latest technology whilst producing the best products.
The 321 UNS S32100 ERW Pipe is produced through a welded joint in their cross-section. These pipes are joined together with electricity and are very long-lasting. The 1.4541 SS 321 Seamless Tube is non-magnetic in nature and cannot be hardened by hot-rolling procedures. These tubes also have excellent low-temperature working properties. The AISI 321 Schedule 40 Pipe is made up of thin walls. These pipes are preferred for low-pressure applications but work well in high-pressure systems as well. We belong to the group of 321 Tubing suppliers who can customize all our products in different shapes and sizes as per our client's requirements.
The ASTM A312 TP 321 Round Pipe is the most preferred pipe shape amongst the different shapes of pipe available. This pipe may either be welded or seamless and is used to transports fluids and gases. The SA 312 TP 321 Rectangular Pipe is manufactured with a rectangular cross-section. These pipes are extremely strong and require low maintenance. 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. The Cres 321 Tubing is available in AMS ASTM, 2D, and annealed finishes and can be customized as per your requirements.
