Stainless steel bar refers to a bar-shaped piece of stainless steel, a corrosion-resistant alloy of steel containing a minimum of 10.5% chromium content by mass. Stainless steel bars are used in a wide variety of applications due to their excellent resistance to corrosion, strength, and versatility. They are available in different shapes, sizes, and grades, and can be used in both structural and aesthetic applications.
Types of Stainless Steel Bars
Round Bar: A cylindrical shape, often used in machining, construction, and manufacturing of various components. |
Flat Bar: A rectangular bar, commonly used for structural purposes or as a base for various machining operations. |
Square Bar: A bar with equal length sides, typically used for manufacturing and fabrication, as well as for aesthetic purposes. |
Hexagonal Bar: A six-sided bar often used in specialized applications like bolts and fasteners. |
Angle Bar: Stainless steel bars with a "L" shape, useful in framing and other structural applications. |
