These flanges are crafted according to international standards, making them perfect for critical applications in sectors like power generation, petrochemicals, chemical processing, and marine industries. Supachok Flanges prides itself on delivering precision-engineered, reliable, and cost-effective solutions that ensure consistent performance even in the toughest conditions. With cutting-edge manufacturing techniques, rigorous quality control, and a strong focus on customer satisfaction, the company provides flanges that promise safety, efficiency, and a long service life, making them a go-to choice for industrial applications that demand strength and reliability.
Stainless Steel 348 Flanges are made up of iron, 17–19% chromium, 9–13% nickel, along with trace amounts of niobium, manganese, and carbon. This unique blend gives them outstanding resistance to intergranular corrosion, high-temperature oxidation, and stress corrosion cracking. On the mechanical side, they boast high tensile and yield strength, impressive impact toughness, and excellent creep resistance. The addition of niobium helps stabilize the grain structure and maintain dimensional stability at high temperatures, making 348 flanges perfect for high-temperature piping systems and equipment that need to perform reliably over the long haul in challenging industrial settings.
