Stainless Fin Tube

Stainless steel fin tubes are processed out of various grades of both seamless and welded plain tubes. Plain stainless steel tubes will be procured from well known indian plain tube manufacturers, as per material specification and customer requirement, for processing fin tubes. Plain stainless steel tubes will be procured for finning, duly hydro tested and eddy current tested as per material specification and code, from plain tube manufacturers only, as per customer requirement. If customer require, we will procure plain stainless steel tubes, duly inspected, approved and released by customer or third party inspection agency, at plain tubes manufacturer’s end.

Why Use Stainless Steel?

Stainless Steel has a diversified application, because unlike other metals, Stainless Steel has certain characteristics that make the specialty metal a safe and cost-effective choice to a variety of manufacturers. Those characteristics include:

  • Good corrosion resistance
  • Smooth Surface
  • High Strength
  • Malleability
  • Easy Maintenance

Stainless Steel is a choice material is such industries as: Aerospace, Appliance, Architecture & Construction, Automotive, Chemical Processing, Electronic, Food Service, HVAC, Medical, Marine, Power Generation, Oil and Gas, and Tool and Die.

300 Series in Finned Tubing

300 Series Stainless is a particularly popular choice when it comes to the manufacturing of Finned Tubing. Type 301 Stainless Steel is an austenitic chromium-nickel Stainless Steel that provides high strength and good ductility when cold worked. 304 Stainless Steel is, in the annealed condition, essentially non-magnetic and becomes slightly magnetic with the application of cold work. Type 304L Stainless Steel is preferred in welding applications. Type 316 Stainless Steel is an austenitic chromium nickel Stainless Steel containing molybdenum. This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. These are just some of the many grades of Stainless Steel that Grand stocks in our inventory. When it comes to Finned Tubing, corrosion resistance can be key. That’s why customers come to us when sourcing material for this application. We’ve got you covered.

400 Series in Finned Tubing

400 Series Stainless, on the other hand, boasts additional features that might appeal to this particular end-user. 400 Series Stainless, particularly 409, 430 and 439, provide improved oxidation and corrosion resistance compared to carbon steel. When application temperatures are too high for Type 409, Type 439 provides good oxidation and corrosion resistance for many automotive exhaust system components and residential furnace primary heat exchangers.
