ASTM A312 TP430 Ferritic Stainless Steel Seamless Pipe

Cost-Effective Ferritic Stainless Steel with Excellent Oxidation Resistance and Magnetic Properties for Food Equipment, Automotive, and Decorative Applications

📌 Quick Details

📝 Product Description

ASTM A312 TP430 is a ferritic stainless steel containing approximately 16-18% chromium with no nickel content, offering a cost-effective alternative to austenitic grades like 304. With good corrosion resistance in mildly corrosive environments and excellent oxidation resistance at elevated temperatures, TP430 is the material of choice for applications where magnetic properties are beneficial and extreme corrosion resistance is not required.

Our TP430 seamless pipes are cold drawn from premium mill-certified hollow bars, ensuring consistent dimensional accuracy and a smooth surface finish. The ferritic structure provides magnetic properties, high thermal conductivity, and low thermal expansion compared to austenitic grades—key advantages in heat exchanger and thermal cycling applications. With competitive pricing typically 40-50% lower than 304, TP430 delivers outstanding value for the right applications.
