430 Stainless Steel Round Bar
Stellanox Steel provides durable and cost-effective 430 Stainless Steel Round Bars, ideal for applications where moderate corrosion resistance, excellent formability, and magnetic properties are desired. As a ferritic stainless steel, 430 round bars offer good mechanical strength, oxidation resistance, and superior polishability—making them suitable for automotive, kitchen, architectural, and industrial applications.
This non-hardenable, chromium-rich grade offers a balance of performance and affordability in less aggressive environments.
What is 430 Stainless Steel Round Bar?
430 Stainless Steel Round Bar is a straight-chromium ferritic stainless steel alloy containing approximately 16–18% chromium. It offers good corrosion resistance in mildly corrosive environments and resists oxidation at elevated temperatures. 430 round bars are magnetic and retain their structure even under moderate stress and thermal exposure.
These bars are not heat treatable but can be cold worked to improve mechanical strength. They are commonly used in architectural trims, appliance components, and structural frames.
