Stainless Steel 430 Properties

Ferrobend is a trusted name in the stainless steel industry, specializing in the production and supply of high-quality Stainless Steel 430 products. Our expertise in the manufacturing process ensures that every piece of stainless steel we produce meets the highest standards of durability, strength, and versatility, making it the material of choice for a wide range of industries. Stainless Steel 430 is a ferritic, magnetic grade of stainless steel known for its excellent resistance to oxidation and corrosion in mildly corrosive environments. It contains a significant amount of chromium, typically around 16-18%, which contributes to its corrosion resistance and makes it highly durable. While not as resistant to corrosion as the more commonly used 304 stainless steel, Stainless Steel 430 provides a cost-effective alternative in various applications. At Ferrobend, we specialize in manufacturing Stainless Steel 430 in different forms and specifications to meet diverse customer needs. With our state-of-the-art facilities and advanced manufacturing techniques, we ensure that each product we create is of the highest quality and precisely crafted to meet your unique requirements.

At Ferrobend, we offer a wide range of sizes, thicknesses, and forms of Stainless Steel 430 to suit a variety of applications, including sheets, coils, bars, and pipes. Our manufacturing flexibility ensures we can meet your specific design requirements. Stainless Steel 430 is often chosen for its affordability in comparison to other stainless steel grades. Our efficient manufacturing processes allow us to offer competitive pricing without compromising on quality. Stainless Steel 430 is known for its resistance to corrosion, oxidation, and wear, making it a perfect choice for long-term use in demanding applications. Whether it’s in kitchen equipment, automotive parts, or industrial machinery, Ferrobend’s Stainless Steel 430 products are built to last. While not as resistant as austenitic grades, 430 stainless steel offers exceptional resistance in moderately corrosive environments, including many types of acid and salt exposure, making it ideal for use in kitchen appliances, heat exchangers, and other demanding environments.

Stainless Steel 430 is its cost-effectiveness compared to other stainless steel grades, particularly the austenitic grades like 304 stainless steel. The lower cost is largely due to the absence of nickel, which makes 430 stainless steel less expensive to produce. The affordability of Stainless Steel 430 does not compromise its performance. In environments where extreme corrosion resistance is not necessary, 430 stainless steel provides an excellent balance between cost and performance. This makes it a perfect choice for applications in industries such as automotive manufacturing, home appliances, and food processing. Ferrobend is your trusted partner for all things Stainless Steel 430. Our high-quality products, competitive prices, and commitment to excellence make us a leading manufacturer in the stainless steel industry. Whether you need Stainless Steel 430 for home appliances, automotive applications, or industrial machinery, Ferrobend offers the ideal solution.

Heat Resistance:

  • Good oxidation resistance at temperatures up to 1700oF (927 oC)
  • Continuous use at temperatures above 1400oF (760oC) is not usually recommended due to carbide precipitation which can lead to irregular scaling
  • Does not have a low carbon content so it is also vulnerable to sensitization

Welding Characteristics:

  • Not generally recommended, but may be welded with some difficulty
  • May be welded with Alloy 310 electrodes
  • Should be annealed after welding to re-dissolve precipitated carbides

Machinability:

  • High machining rates can be obtained in the annealed condition with hardness in the range of 200 to 240 Brinell
  • Will work harden; therefore, it should be machined at reduced surface feet per minute and heavier feeds to prevent glazing at the tool interface.

Applications:

  • Nuts and bolts
  • Aircraft fittings
  • Gears
  • Screws
  • Shafts
  • Electrical switchgear components
  • Bushings
