Quantity
The UNS S31254 Fastener is manufactured from 254SMO super austenitic stainless steel, a high-performance material specifically developed for aggressive chloride-bearing environments. Available in sizes from 5/16 to 4 inches and lengths ranging 30 to 800 mm, these fasteners comply with ANSI and DIN standards to meet diverse industrial requirements.
With a minimum tensile strength of 650 N/mm² and elongation of 35%, the UNS S31254 Fastener delivers an optimal balance of mechanical strength and ductility. The alloy's high molybdenum (≈6%) and nitrogen content delivers a PRE value exceeding 42, providing exceptional resistance to pitting and crevice corrosion . This makes the UNS S31254 Fastener particularly suitable for petrochemical equipment, offshore platforms, seawater systems, and chemical processing plants where chloride-induced corrosion poses significant challenges . Whether in high-temperature, high-pressure conditions or marine environments, these fasteners ensure reliable, long-term equipment operation.
