Weston Stainless, Midland, UK, is a world-class supplier of stainless steel items of high quality, with specialties in industrial components like flanges and fasteners. Of its high-end products, Stainless Steel 347H Flanges stand out for their exceptional high-temperature strength and resistance to intergranular corrosion. SS 347H is a high-carbon version of grade 347, engineered to provide greater creep resistance and hardness. These flanges are available in a wide range of shapes, such as weld neck, slip-on, blind, socket weld, and threaded flanges, and can be used in a broad spectrum of applications. Made from high–quality stainless steel, SS 347H Flanges offer great mechanical strength, resistance to oxidation, and extended service life.
Stainless Steel 347H Flanges contain 17-19% chromium, 9-13% nickel, and an increased level of carbon (0.04-0.10%), with added niobium for enhanced stabilization against carbide precipitation. They have superior mechanical properties such as tensile strength of approximately 515-700 MPa, yield strength of about 205-275 MPa, and elongation of 40%. The hardness of SS 347H Flanges ranges between 160-190 HB, which makes them durable under severe conditions. Physically, these flanges are of density 7.93 g/cm³, have good thermal conductivity, and a high melting point, which makes them suitable for applications at high temperatures.
