Stainless Round Bar 303 Metric is one of the easiest stainless steel alloys to machine, grind and polish. Toughness and corrosion resistance are slightly lower than most other stainless steels as a result. It is typically used in aircraft applications, machine parts, pump and valve parts, architectural applications, nuts, and bolts.

The 303 stainless steel round bar is one of the easiest stainless steel alloys to machine, grind, and polish, making it ideal for applications requiring detailed machining.

While it offers some corrosion resistance, the 303 alloy has slightly lower toughness and corrosion resistance compared to other stainless steels, so it is best used in applications like aircraft parts, pumps, valves, and architectural components.

This product is available in a standard length of 72 inches with a tolerance of plus or minus 2 inches. Custom cut options are not available from the warehouse for this item.

Yes, this stainless steel round bar complies with RoHS and REACH regulations and meets ASTM A276 and A582 standards.

Yes, a Material Test Report (MTR) is available for this product to verify its chemical and mechanical properties.
