Nakamura Stainless stands out as a top-notch manufacturer and supplier based in Pulau Ujong, Singapore, focusing on high-quality stainless steel products that are built to last and perform exceptionally. Among their impressive lineup, the Stainless Steel 317L Bolts shine for their remarkable resistance to corrosion, especially in harsh chemical and chloride-heavy environments. Thanks to the addition of molybdenum and a low carbon content, these bolts offer superior strength, pitting resistance, and a minimized risk of carbide precipitation. Crafted with precision, Stainless Steel 317L Bolts deliver reliable fastening solutions for demanding industrial applications around the globe.
These bolts are made up of 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, all while maintaining a low carbon content. This unique blend enhances their resistance to intergranular corrosion, crevice corrosion, and pitting, particularly in chloride-rich settings. On the mechanical side, they boast high tensile and yield strength, outstanding toughness, and creep resistance even at elevated temperatures. Their perfect mix of strength and corrosion resistance makes them both durable and trustworthy in tough conditions.
