436 Stainless Steel Plate/Sheet Details
Overview
436 stainless steel plate/sheet is a ferritic stainless steel with enhanced corrosion and oxidation resistance, combined with good formability and weldability. This alloy is a modification of 430 stainless steel, with the addition of columbium (niobium) to improve its resistance to intergranular corrosion and enhance its mechanical properties.
Key Characteristics
Corrosion Resistance: Provides excellent resistance to corrosion, particularly in oxidizing environments.
Oxidation Resistance: Maintains good oxidation resistance at elevated temperatures.
Enhanced Formability: Offers improved formability over standard 430 stainless steel due to the addition of columbium.
Weldability: Can be easily welded with standard techniques, making it versatile for various applications.
Magnetic Properties: Exhibits magnetic properties in both the annealed and cold-worked conditions.
Chemical Composition
Carbon (C): ≤ 0.12%
Manganese (Mn): ≤ 1.00%
Silicon (Si): ≤ 1.00%
Phosphorus (P): ≤ 0.040%
Sulfur (S): ≤ 0.030%
Chromium (Cr): 16.0-18.0%
Nickel (Ni): ≤ 0.75%
Columbium (Cb/Nb): 0.3-1.0%
Common Applications
Automotive Trim: Used in automotive trim and molding applications due to its good formability and corrosion resistance.
Exhaust Systems: Employed in automotive exhaust systems where high-temperature oxidation resistance is required.
Kitchen Appliances: Suitable for kitchen appliances such as sinks, oven liners, and range hoods for its corrosion resistance and aesthetic appeal.
Architectural Applications: Ideal for architectural elements like building facades and decorative trim, offering durability and visual appeal.
Food Processing Equipment: Used in food processing equipment for its non-reactive surface and ease of cleaning.
Advantages
