440 Stainless Steel Plate Manufacturers
400 series stainless steel is a type of stainless steel with a ferrite or martensite structure. It has high corrosion resistance and strength and is commonly used in various industrial and daily applications. Compared with 300 series austenitic stainless steel, the 400 series contains no or less nickel and is more economical. The main component includes chromium (usually between 10.5% and 30%), which gives it corrosion resistance.

- 409: Contains titanium, good weldability, high-cost performance, suitable for automotive exhaust systems, etc.
- 410: Martensitic steel, with high strength and hardness, suitable for knives, tools, etc.
- 420: High carbon content, good hardness, and wear resistance, commonly used in knives and medical devices.
- 430: Ferritic steel, nickel-free, low cost, suitable for home appliances and decorative applications.
- 440C: High carbon and high chromium, extremely high hardness and wear resistance, suitable for high wear-resistant knives.
- 441: Contains titanium and niobium, excellent high-temperature oxidation resistance and corrosion resistance, suitable for high-temperature environment.
400 Series Stainless Steel Performance Comparison
- 409 and 441: They show good weldability and high-temperature resistance, and are suitable for automotive exhaust systems and high-temperature environments. 441 has better performance than 409 due to the addition of titanium and niobium.
- 410 and 420: They have high strength and hardness, and are suitable for applications with high mechanical strength requirements. 420 has higher hardness, but weaker corrosion resistance.
- 430: It is widely used in kitchen equipment, home appliances, and other fields. It is inexpensive and has good corrosion resistance and formability.
- 440C: It has the highest hardness and strength and is suitable for high wear resistance occasions, but the processing and welding performance are poor.
Cost Comparison:
The 400 series is relatively cheap because it contains low or no nickel, which is one of the main factors affecting the price of stainless steel.
430 Stainless Steel
- Features: As the most commonly used ferritic stainless steel, 430 does not contain nickel, is usually cheaper, and has good corrosion resistance.
- Price: Generally about 70% to 80% of the price of 300 series stainless steel, suitable for projects with limited budgets.
410 Stainless Steel
- Features: A martensitic stainless steel with high strength and hardness, but poor corrosion resistance.
- Price: Slightly higher than 430, but still lower than 300 series, especially austenitic steel with more nickel.
420 Stainless Steel
- Features: Mainly used for manufacturing knives, tools, etc., with high hardness and good wear resistance.
- Price: Due to its characteristics and uses, the price of 420 is slightly higher than 410, but it is still a medium to low price level.
409 Stainless Steel
- Features: Used in automotive exhaust systems, with good heat resistance and high-cost performance.
- Price: Slightly lower than 430, suitable for mass production and high-temperature environments.
Main types of 400 Series Stainless Steel:
Ferritic Stainless Steel
- Features: Ferritic stainless steel has a high chromium content, low carbon content, good thermal conductivity, and excellent oxidation resistance, but low toughness and poor welding performance.
- Representative grades: 430, 409, 439.
- Applications: automotive exhaust systems, household appliances, architectural decoration, etc.
Martensitic Stainless Steel
- Features: It has a high carbon content, high strength, and hardness, and excellent wear resistance, but relatively weak corrosion resistance.
- Representative grades: 410, 420, 440.
- Applications: knives, bearings, medical equipment, tools, etc.
Characteristics of 400 Series Stainless Steel:
- Corrosion Resistance: Although the corrosion resistance of 400 series stainless steel is not as good as that of 300 series, it performs well in atmospheric and freshwater environments, and is particularly suitable for applications where corrosion resistance is not required.
- Mechanical Properties: Martensitic stainless steel has high strength and hardness, and is suitable for making parts that require high strength and wear resistance. Ferritic stainless steel has good thermal conductivity and is suitable for making equipment such as heat exchangers and heaters.
- Machinability: Due to its low nickel content, 400 series stainless steel has good machinability, and is particularly suitable for forming and cutting.
