304 stainless steel rods are among the most widely used materials in industrial and commercial applications due to their excellent corrosion resistance, mechanical properties, and affordability. Whether you’re in manufacturing, construction, or precision machining, choosing the right 304 rod involves understanding material composition, dimensions, and surface finishes.

Choosing the Right Rod for Your Application
-
Mechanical Applications: Select tighter tolerance (h9/h10) for CNC machining.
-
Decorative Use: Opt for mirror-polished finish.
-
Corrosive Environments: Ensure it’s standard 304, not 304L, for better strength.
-
High-Volume Production: Look for peeled and straightened rods to reduce machining time.
