Stainless Steel Alloy 455 | Product Properties, Composition & Machinability

Stainless Steel Alloy 455 is a martensitic age-hardening stainless steel that offers a unique combination of high strength, corrosion resistance, and ease of fabrication. It contains significant amounts of chromium, nickel, and molybdenum, which contribute to its exceptional corrosion resistance, especially in harsh environments containing chloride and seawater. Alloy 455 can be precipitation-hardened to achieve higher mechanical properties, making it suitable for applications in marine, aerospace, and oil and gas industries. Its combination of strength and corrosion resistance makes it a preferred choice for various structural and critical components exposed to challenging conditions. Additionally, its ease of fabrication adds to its appeal in engineering and manufacturing processes.
