FAQ

What is the difference between 304 stainless steel and other grades?

304 stainless steel offers a balanced combination of corrosion resistance, formability, and strength, making it ideal for general‑purpose industrial parts. It performs better than lower‑grade steels in humid or corrosive environments while remaining easier to machine than higher‑grade alloys.

Can this round bar be heat‑treated after purchase?

Yes, the bar can be annealed or hardened to meet specific mechanical requirements. However, any heat‑treatment should be performed by a qualified professional to maintain dimensional accuracy.

Is the pack of ten suitable for large‑scale production?

The ten‑piece pack provides a convenient inventory for small to medium production runs, prototyping, and maintenance stock. For larger volumes, bulk ordering options are available upon request.

How should the bar be stored to preserve its quality?

Store the bars in a dry, well‑ventilated area away from direct sunlight and corrosive chemicals. Keeping them in their original packaging helps protect the surface finish until use.

What machining tolerances can be expected?

TOPPROS guarantees a diameter tolerance of ±0.02 mm and straightness within 0.1 mm over the full 300 mm length, ensuring high precision for demanding applications.
