Overview of 304 and 430 Stainless Steel
304 Stainless Steel (Austenitic)
304 is the most widely used stainless steel worldwide. It contains 18% chromium and 8% nickel, offering excellent corrosion resistance, formability, and toughness.
Category: Austenitic stainless steel
Corrosion resistance: Excellent
Weldability: Excellent
Magnetism: Non-magnetic
Typical uses: Kitchens, food equipment, chemical containers, building decoration, automotive parts
If you need 304 stainless steel sheet, coil, strip, or plate, Huaxiao Metal can supply customized sizes and surface finishes.
430 Stainless Steel (Ferritic)
430 stainless steel contains 17% chromium without nickel, making it more economical than 304 while still offering good corrosion resistance in mild environments.
Category: Ferritic stainless steel
Corrosion resistance: Moderate
Weldability: Good
Magnetism: Strongly magnetic
Typical uses: Home appliances, indoor decoration, automotive trim, kitchen appliances
For cost-sensitive projects, 430 is a popular choice.
Features and Advantages of 304 Stainless Steel
304 stainless steel is a commonly used material with several advantages. It contains 18% chromium and 8% nickel and has excellent corrosion resistance and high-temperature resistance. 304 stainless steel has good heat resistance and is suitable for manufacturing various pressure vessels, pipelines, and chemical equipment. In addition, it also has good processability and weldability and is easy to process into various shapes. Therefore, 304 stainless steel is widely used in the manufacturing and food processing industries.
Features and Advantages of 430 Stainless Steel
430 stainless steel is a low-cost stainless steel material mainly containing iron and chromium. Compared with 304 stainless steel, 430 stainless steel has a lower chromium content, only about 16%. Although 430 stainless steel has poor corrosion and high-temperature resistance, it has good wear and magnetic resistance. Therefore, 430 stainless steel is often used in home appliances, automotive exteriors, and kitchen utensils. Its low cost and ease of maintenance make it an economical and practical choice.
Comparison of 304 vs 430 Stainless Steel
Although both 304 vs 430 stainless steel are stainless, they differ in their corrosion resistance and high-temperature resistance. 304 stainless steel performs better in these aspects and is suitable for use in applications with harsh environmental requirements. On the other hand, 430 stainless steel has poor corrosion resistance and high-temperature resistance, but it has strong wear resistance and magnetic resistance and is suitable for some specific application scenarios.
304 Stainless Steel Application Areas:
1.1 With heat resistance, good processing characteristics, and high flexibility, it is it is widely used in industrial production, and furniture decoration industry, and the food medical industry.
1.2 has very strong corrosion resistance, widely used in the production of equipment and mechanical parts that provide good comprehensive performance (corrosion resistance and molding).
304 Stainless Steel Products
430 Stainless Steel Application Areas:
2.1 Apply to building decoration, fuel burner parts, household appliances, home appliance parts, and other fields.
2.2 Adding easy-cutting performance steel 430F to 430 steel is suitable for automatic lathes, screws, and bolts.
2.3 Add Ti or Nb in 430 steel, reduce C content into 430LX, improve processing characteristics and welding characteristics, welding for hot water tanks, hot water systems, environmental sanitation appliances, household life with the use of appliances, bicycle chains, and so on.
2.4 430 stainless steel is not food grade, 430 is categorized as ferritic stainless steel, magnetic, commonly known as stainless steel, used to do CNC blades and other kitchen utensils are usually used at this stage of the austenitic stainless steel (without magnetic or with micro-magnetic), so 430 stainless steel to do the kitchen utensils is not very safe because 430 stainless steel is corrosion-resistant performance is not good.

✔ 430 has higher hardness and good anti-fingerprint performance, suitable for appliance panels.
Price: 304 Vs 430 Stainless Steel
430 stainless steel is cheap: because it does not contain nickel and has a simple production process, its market price is generally lower than 304 stainless steel.
304 stainless steel is expensive: because it contains more nickel and chromium, it has excellent corrosion resistance and mechanical properties, and its cost and market price are higher.
If price is the primary consideration and corrosion resistance is not required, it is more economical to choose 430 stainless steel; if you pursue higher performance and durability, 304 stainless steel is a better choice.
