Nakamura Stainless, located in Pulau Ujong, Singapore, is a trusted manufacturer and supplier of high-quality stainless steel products, including stainless steel 317L bars. These bars are specifically designed for highly corrosive environments and provide excellent resistance to chemical attacks, particularly in acidic and chloride-rich conditions. Stainless steel 317L is a low-carbon alloy with molybdenum and offers better corrosion resistance than 316L. Nakamura Stainless ensures precise manufacturing and strict quality control, making their 317L bars suitable for industries such as chemical processing, pulp and paper, marine, and pharmaceutical production.
Stainless steel 317L bars contain about 18 to 20% chromium, 11 to 15% nickel, and 3 to 4% molybdenum, with reduced carbon content for better weldability and resistance to intergranular corrosion. These bars have a tensile strength of approximately 515 to 760 megapascals and retain good mechanical properties in both high-temperature and corrosive conditions. The added molybdenum enhances resistance to pitting, crevice corrosion, and general chemical attacks, especially in environments with sulfates, chlorides, and other aggressive substances.
