MERIH STAINLESS, located in Istanbul, Turkey, stands out as a top manufacturer and supplier of premium stainless steel products, with a special focus on precision-engineered Stainless Steel 317 Nuts. Known for their impressive strength, durability, and outstanding resistance to corrosion, these nuts are crafted using cutting-edge production techniques and rigorous quality control measures. MERIH STAINLESS caters to a variety of industries, including chemical processing, marine, pharmaceuticals, and food processing, ensuring that every nut adheres to international standards. With a strong commitment to timely deliveries, customization options, and customer satisfaction, the company has earned a reputation as a reliable source for fastening solutions around the globe.
Stainless Steel 317 Nuts are crafted from an austenitic chromium-nickel-molybdenum alloy, which provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, especially when compared to standard 316 stainless steel. Their typical chemical makeup includes 18–20% chromium, 12–15% nickel, 3–4% molybdenum, and a low carbon content of less than 0.03%, ensuring they are easy to weld and maintain structural integrity. On the mechanical side, these nuts boast high tensile strength, yield strength, and toughness, making them reliable even in harsh and chemically aggressive environments.
