Mazin Fasteners caters to various industries, including chemical processing, power generation, oil and gas, and marine engineering. Renowned for their durability, heat resistance, and long lifespan, these fasteners are perfect for tough industrial applications that demand secure and reliable fastening in harsh conditions.
The Stainless Steel 304H Fasteners are made from a high-carbon austenitic stainless steel alloy, featuring around 18–20% chromium and 8–10% nickel, with a higher carbon content than standard 304 to boost strength at elevated temperatures. This unique composition offers outstanding corrosion resistance, especially in oxidizing and high-temperature settings, while still providing good ductility and toughness. On the mechanical side, SS 304H fasteners deliver high tensile and yield strength, stable hardness, and consistent performance under thermal and mechanical stress. They maintain their shape and resist deformation even during prolonged exposure to high temperatures.
