They’ve built a solid reputation for delivering top-notch products that adhere to international standards. With a keen focus on precision engineering and durability, Emilio Stainless provides a wide array of 348H flanges that are specifically designed to withstand high temperatures and corrosive environments. These flanges are known for their impressive resistance to intergranular corrosion and oxidation, making them perfect for demanding industrial applications. Supported by state-of-the-art manufacturing facilities and a strong commitment to quality, Emilio Stainless guarantees reliability, strength, and outstanding performance in every Stainless Steel 348H flange they supply.
The composition of Stainless Steel 348H Flanges primarily includes **chromium (17-19%)**, **nickel (9-13%)**, along with added **niobium and carbon** to boost high-temperature strength. The “H” grade signifies a higher carbon content, which enhances creep resistance and mechanical stability. These flanges boast remarkable tensile strength of about **515 MPa**, yield strength of **205 MPa**, and an elongation of **40%**. With a melting point of roughly **1398°C**, they provide exceptional resistance to oxidation and corrosion, even when continuously exposed to high temperatures in harsh environments.
