Nakamura Stainless, located in Pulau Ujong, Singapore, is a trusted manufacturer and supplier of high-quality stainless steel products, including stainless steel 330 stud bolts. These stud bolts can handle extreme high temperatures and provide excellent resistance to oxidation, thermal fatigue, and corrosion. Stainless steel 330 is a high-temperature austenitic alloy that offers exceptional strength and stability at temperatures up to 1150°C. Nakamura Stainless ensures precise manufacturing and strict quality control, which makes their 330 stud bolts perfect for critical applications in power plants, petrochemical industries, and furnace components.
Stainless steel 330 stud bolts mainly consist of about 34–37% nickel, 19–23% chromium, and 1–2% copper, giving them outstanding strength and oxidation resistance at high temperatures. These bolts have a tensile strength ranging from 620 to 850 megapascals and maintain their mechanical integrity even with prolonged thermal exposure. The alloy’s composition also provides excellent creep resistance and thermal fatigue resistance, making it suitable for tough operating conditions.
