Weston Stainless, Midland, UK, is a prominent manufacturer of high-quality stainless steel items, with specializations in industrial parts such as flanges and fasteners. Among its top-of-the-line products, Stainless Steel 348H Flanges stand out due to their superior high-temperature strength and superior resistance to intergranular corrosion. SS 348H is a high-carbon version of grade 348, offering increased creep resistance and toughness. These flanges are available in different shapes such as weld neck, slip-on, blind, socket weld, and threaded flanges to provide versatility. Being made of high-quality stainless steel, SS 348H Flanges provide superior oxidation resistance, mechanical properties, and durability for harsh applications.
Stainless Steel 348H Flanges consist of 17-19% chromium, 9-13% nickel, and increased carbon content (0.04-0.10%), along with niobium for added stabilization. They display very good mechanical properties with a tensile strength of about 550 MPa, a yield strength of about 220 MPa, and an elongation of 35%. SS 348H Flanges possess hardness of 160-190 HB, guaranteeing durability under severe conditions. Physically, these flanges possess a density of 7.93 g/cm³, high thermal conductivity, and thermal expansion characteristics, which make them perfect for applications in high temperature and high pressure.
