Welded Steel SS316 Pipe

FAQ's on Welded Steel SS316 Pipe

In this article you will find the most frequently asked questions (FAQ's) and answers about Steel and Stainless Steel pipe or tubing. Please read on!

  Q: What is the "Official" name for stainless? 
  A: Stainless Steel. It literally means, "steel with no stain".

  Q: Does Stainless Steel Rust?   
  A: Yes, it can rust under certain harsh environmental conditions. 
        However, Stainless Steel will generally have a much higher res 
        istance to rust than steel in normal environmental conditions.

  Q: What does the acronym SUS mean? 
  A: SUS stands for Steel Used Stainless.

  Q: What does SUS with an "L" stand for? 
  A: The L indicates "low carbon" SUS. The lower carbon content 
        improves the corrosion resistance of the material especially 
        after weldi

  Q: What is the chemical symbol for Stainless Steel? 
  A: There is no chemical symbol for Stainless Steel.

  Q: Can Stainless Steel be magnetized? 
  A: Yes. Ferritic and Martensitic Stainless Steels are magnetic. 
        Austenitic Stainless Steels are not. Please refer to the Material 
        Qualities of Stainless and Steel Pipe section for more information.

  Q: How does Stainless Steel compare to Steel in weight? 
  A: The specific gravity of Stainless is 7.93 (for SUS 304) and 
        Steel is 7.87, therefore they weigh nearly the same.

  Q: Can Stainless Steel be heat treated to increase the hardness? 
  A: Martensitic Stainless Steel can be hardened using quenching 
        and tempering. Ferritic and Austenitic Stainless Steels cannot.

  Q: Is there a difference in thermal conductivity between Stainless 
       Steel and Steel? 
  A: Yes. Stainless Steel has a lower thermal conductivity rate than 
        steel; approximately 1/3 to 1/5th depending on the material.

  Q: Is there a difference in electrical conductivity between Stainless 
       Steel and Steel? 
  A: Yes. Steel is generally more conductive than Stainless Steel. 
        Steel has resistivity in the range of 10~20 Ωm, while Stainless 
        has a resistivity of approximately 60~72 Ωm.

  Q: What is the market price or price indicator of Stainless Steel 
       materials? 
  A: The price for Stainless material fluctuates with the pricing of other 
        raw materials such as: Steel, Chrome, Nickel and others. 
        The general market price indicator is the London Metal Exchange 
       (LME). Here is a link: (Insert LME link here)
