Nakamura Stainless, located in Pulau Ujong, Singapore, is a reliable manufacturer and supplier of high-quality stainless steel products, including stainless steel 317 bolts. These bolts are made for harsh environments and provide excellent resistance to chemicals, especially in acidic and chloride-rich conditions. Stainless steel 317 is a molybdenum-containing austenitic alloy that has better corrosion resistance than 316. Nakamura Stainless makes sure that each bolt is manufactured precisely under strict quality controls, making them suitable for critical applications in the chemical, marine, pharmaceutical, and pulp and paper industries.
Stainless steel 317 bolts consist of about 18 to 20% chromium, 11 to 15% nickel, and 3 to 4% molybdenum. This mix gives them great resistance to pitting, crevice corrosion, and general chemical attack, particularly in acidic, sulfurous, and chloride-heavy environments. These bolts usually offer tensile strength ranging from 515 to 760 megapascals and maintain strong mechanical properties at both room and high temperatures. Their austenitic structure also allows for good weldability and formability in various assembly applications.
