- Typical composition: 17-19% chromium, 9-12% nickel, titanium content
- Applications: High-temperature equipment, chemical processing, power generation
For all of these stainless steel square bars, the "cold drawn bright" finish refers to a manufacturing process where the bars are drawn through a die to achieve tight dimensional tolerance and a smooth, shiny surface finish.
The square shape provides a more uniform cross-section compared to round bars, which can be beneficial for certain applications. The stainless steel composition ensures high strength, corrosion resistance, and durability.
