Mazin Fasteners caters to various industries, including petrochemical, chemical processing, power generation, and marine engineering. Renowned for their durability, thermal stability, and resistance to intergranular corrosion, these nuts are perfect for critical applications that demand secure and long-lasting fastening in extreme heat and harsh environmental conditions.
The Stainless Steel 347H Nuts are made from a stabilized austenitic stainless steel alloy, which contains about 17–19% chromium, 9–13% nickel, and niobium to prevent intergranular corrosion. With a higher carbon content than 347, they offer improved high-temperature strength. On the mechanical side, SS 347H nuts boast high tensile and yield strength, excellent hardness, and stability under thermal and mechanical stress. They deliver reliable performance even in prolonged elevated-temperature service, resisting deformation, fatigue, and oxidation.
