ASTM A182 F60 Fasteners are crafted from duplex stainless steel containing a balanced mix of chromium, nickel, molybdenum, and nitrogen. This unique dual-phase structure delivers superior strength and excellent corrosion resistance, especially in chloride-rich environments. They typically offer high tensile and yield strength, outstanding resistance to pitting and crevice corrosion, and reliable performance under stress. With hardness generally below 290 HB and elongation around 25%, these fasteners provide durability, stability, and long-term reliability, making them suitable for harsh and high-pressure operating conditions.

ASTM A182 F60 Fasteners are widely used across industries that demand both high mechanical strength and superior corrosion resistance. Their robust duplex structure makes them ideal for offshore platforms, marine engineering, desalination plants, and coastal installations exposed to saltwater. In the oil and gas sector, they play a vital role in piping systems, pressure vessels, heat exchangers, and subsea equipment. Chemical processing plants rely on them for their resistance to acidic and chloride-bearing environments. These fasteners are also used in pulp and paper mills, structural projects, and industrial machinery where dependable, long-lasting fastening performance is essential.
Our ASTM A182 F60 fasteners are meticulously packed to ensure they remain undamaged during transportation. For international shipments, we employ standard export packaging in robust wooden boxes or cases, adhering strictly to global packing norms. Each fastener is prominently marked with our trademark (Company’s LOGO), Grade (ASTM A182 F60), Size, and Lot Number for clear identification. Upon customer request, we provide customized markings as well.
