MERIH STAINLESS, located in Istanbul, Turkey, stands out as a top manufacturer and supplier of high-quality Stainless Steel 317L Nuts, designed specifically for exceptional corrosion resistance in tough environments. Renowned for their durability, strength, and reliability, these nuts offer secure fastening solutions for demanding industrial applications. Crafted with precision and in line with international standards, MERIH STAINLESS guarantees that its Stainless Steel 317L Nuts provide long-lasting performance. They find extensive use in industries such as chemical processing, petrochemical, marine, and power generation, where resistance to pitting, crevice corrosion, and stress corrosion cracking is crucial for safe and efficient operations.
Stainless Steel 317L Nuts are made from low-carbon austenitic stainless steels, containing 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. The low carbon content not only enhances weldability but also minimizes the risk of carbide precipitation, resulting in excellent resistance to intergranular corrosion. In terms of mechanical properties, these nuts boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and they maintain toughness even under corrosive and thermal stress. With outstanding resistance to pitting and crevice corrosion in chloride-rich environments, Stainless Steel 317L Nuts are perfect for critical applications in aggressive chemical and marine settings.
