Crafted to meet international standards, these flanges boast impressive strength, durability, and resistance to oxidation and intergranular corrosion. Supachok Flanges serves a variety of industries, including power generation, petrochemicals, chemical processing, and marine engineering, providing precision-engineered, reliable, and cost-effective flange solutions. Thanks to their advanced manufacturing techniques, strict quality control, and a commitment to customer satisfaction, the company guarantees long-lasting performance, safety, and efficiency, making their Stainless Steel 348H Flanges a go-to choice for critical industrial applications.
The composition of Stainless Steel 348H Flanges includes iron, 17–19% chromium, 9–13% nickel, along with trace amounts of niobium, manganese, and carbon. The “H” designation signifies a higher carbon content, which enhances strength at elevated temperatures. On a mechanical level, these flanges demonstrate high tensile and yield strength, outstanding creep and fatigue resistance, and remarkable impact toughness. The addition of niobium stabilizes the material, ensuring dimensional stability and resistance to intergranular corrosion during extended high-temperature use, making 348H flanges ideal for demanding industrial applications that require durability, reliability, and long-term performance under extreme conditions.
