Alloy 254 SMO – High-Strength, Corrosion-Resistant Stainless Steel
Alloy 254 SMO is a high-alloy austenitic stainless steel engineered for use in seawater, chemical processing, and other aggressive chloride-bearing environments. Known for its exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, 254 SMO offers higher strength and reliability than conventional austenitic stainless steels.
Key Properties of Alloy 254 SMO
- Excellent Corrosion Resistance: Outstanding resistance to pitting and crevice corrosion in chloride-rich environments.
- High Strength: Greater tensile strength than standard austenitic stainless steels.
- Stress Corrosion Resistance: Ideal for applications under tensile stress in corrosive conditions.
- Good Weldability: Can be welded using standard procedures without compromising corrosion resistance.
- Versatile Fabrication: Suitable for tubes, pipes, bars, and forged components.
