Nakamura Stainless, located in Pulau Ujong, Singapore, is a trusted manufacturer and supplier of high-quality stainless steel products, including stainless steel 316H fasteners. These fasteners are built for challenging high-temperature and high-pressure applications. They provide strong resistance to corrosion and are durable. Stainless steel 316H is a high-carbon version of 316, offering improved tensile strength and creep resistance at higher temperatures. Nakamura Stainless guarantees precise manufacturing and strict quality control, making 316H fasteners suitable for power plants, chemical processing, petrochemical industries, and heat treatment systems.
Stainless steel 316H fasteners contain 16 to 18% chromium, 10 to 14% nickel, 2 to 3% molybdenum, and a higher carbon content than standard 316. These fasteners usually have a tensile strength between 515 and 750 megapascals and retain mechanical stability at temperatures up to 870°C. The molybdenum boosts resistance to pitting and crevice corrosion, while the increased carbon content enhances strength and resistance to thermal fatigue.
