400 Series Stainless Steel Strip

Composition and Classification
• Main Composition: An alloy of iron, carbon, and chromium, with little or no nickel, making it a nickel-saving stainless steel, also known as stainless steel.

Performance Characteristics
• Corrosion Resistance: In oxidizing media such as air, fresh water, and nitric acid, with the same chromium content, its corrosion resistance is comparable to that of 300 series stainless steel and superior to that of 200 series stainless steel.
• Physical Properties: High thermal conductivity and low coefficient of expansion, offering excellent high-temperature oxidation resistance and performing well under thermal expansion and contraction conditions and thermal cycling. 400 series stainless steel strip is also magnetic.
• Mechanical Properties: Martensitic stainless steel has high strength and hardness, and its mechanical properties can be adjusted through heat treatment. Ferritic stainless steel has relatively low strength and is generally less tough than austenitic steel.
• Processing Performance: Compared to 300 series stainless steel, it is more difficult to process and has poorer weldability. Ferritic stainless steel is difficult to cold-form, and martensitic stainless steel also presents some challenges in cold-forming.

Common Grades and Applications
• 430: Contains 18% chromium, is inexpensive, has a low thermal expansion coefficient, and offers excellent resistance to chloride stress corrosion. It is used in household appliances, kitchenware, and architectural decoration, such as washing machine drums and kitchen sinks.
• 409L: Offers excellent resistance to high-temperature oxidation and corrosion, primarily used in automotive exhaust systems.

Advantages and Disadvantages
• Advantages: High resistance to high-temperature oxidation, with improved physical and mechanical properties compared to carbon steel. Relatively low price and high cost-effectiveness make it a viable alternative to 300 series stainless steel in applications where corrosion resistance is less critical.
• Disadvantages: Relatively poor formability, weldability, and tensile strength limit its application in certain applications, such as complex-shaped components and those requiring high-strength welding.
