430 Stainless Steel Pipe/Tube Details
Overview
430 stainless steel pipe/tube is a ferritic stainless steel known for its good corrosion resistance, formability, and relatively low cost. It is primarily used in applications where moderate corrosion resistance is required, along with good mechanical properties and ease of fabrication.
Key Characteristics
Corrosion Resistance: Provides good resistance to oxidation and corrosion in moderately corrosive environments, including mildly acidic and alkaline conditions.
Formability: Offers excellent formability and can be easily shaped and fabricated into various forms and sizes, making it suitable for a wide range of applications.
Magnetic Properties: Magnetic due to its ferritic structure, which is a key characteristic for certain applications.
Heat Resistance: Maintains reasonable performance at moderately elevated temperatures but is not as heat-resistant as some other grades.
Weldability: Can be welded using standard techniques, though preheating and post-weld heat treatment are generally not required for most applications.
Chemical Composition
Carbon (C): ≤ 0.12%
Manganese (Mn): 1.00%
Silicon (Si): ≤ 1.00%
Phosphorus (P): ≤ 0.040%
Sulfur (S): ≤ 0.030%
Chromium (Cr): 16.00-18.00%
Nickel (Ni): ≤ 0.75%
