Mira Fasteners, Kuala Lumpur, Malaysia, is a prominent fastening solution provider of corrosion-resistant fastening solutions, among which are **SMO 254 Fasteners**. Due to their superior durability in aggressive and chloride-bearing environments, these fasteners are ideally suited for critical applications in various industries like offshore oil & gas, chemical processing, marine, and desalination. SMO 254 Fasteners are manufactured by Mira Fasteners with emphasis on precision, mechanical strength, and long-term reliability. Manufactured to very high international standards, these fasteners provide secure and safe assemblies in some of the harshest industrial environments on the planet.
**SMO 254 Fasteners** are constructed of a high-alloy austenitic stainless steel with a composition of about 20% chromium, 18% nickel, 6% molybdenum, and include additions of nitrogen and copper. The special chemical composition provides them with superior resistance to pitting, crevice corrosion, as well as chloride-induced stress corrosion cracking. SMO 254 has a very high Pitting Resistance Equivalent Number (PREN) of more than 42.5, much higher than standard stainless steels such as 316L. Due to their superior tensile strength (about 650 MPa), great ductility, and weldability, these fasteners do not suffer from their mechanical strength under harsh conditions of temperature and corrosive environments.
