3 1/2" 430 Stainless Steel Tube/Pipe

 

Product Overview

Grade: 430 Stainless Steel (AISI 430) – A cost-effective, ferritic stainless steel grade engineered for strength, hardness, and moderate corrosion resistance. As a non-hardenable steel with magnetic properties, it is widely used across industries for components that require formability, mechanical integrity, and elevated temperature performance.

Key Features:

• Excellent machinability and moderate corrosion resistance in dry or mildly corrosive environments.

• Heat resistance that ensures stability at elevated temperatures.

• Resistant to scaling and oxidation up to ~870°C (1600°F).

• Ideal for long-term wear-resistance applications such as 430 Stainless Steel Tube in automotive, appliance, and industrial systems.

Due to its lower nickel content compared to austenitic grades like 304 and 316, 430 Stainless Steel Tube is more affordable and suitable for cost-conscious projects that still demand structural strength and longevity.
