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 & Constructie, Automotive, Chemische verwerking, Electronic, Food Service, HVAC, Geneeskundig, Marine, Elektriciteitsproductie, 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 Edelstaal is an austenitic chromium-nickel Stainless Steel that provides high strength and good ductility when cold worked. 304 Edelstaal 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 Edelstaal 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 en 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.
