Aditya Stainless has made a name for itself as a leading manufacturer and supplier of Stainless Steel 310H Flanges in Kolkata, India. They provide top-notch high-temperature flanging solutions to a diverse range of industries. Crafted from stainless steel grade 310H, these flanges are celebrated for their remarkable strength, resistance to oxidation, and performance in high-heat settings. With a higher carbon content than the standard 310, 310H flanges offer enhanced creep resistance and durability. Available in various types like weld neck, slip-on, blind, and threaded flanges, Aditya Stainless ensures precision-engineered products that cater to petrochemical, heat treatment, and furnace applications around the globe.
Stainless Steel 310H Flanges are made up of 24–26% chromium, 19–22% nickel, and a higher carbon content (approximately 0.04–0.10%), which boosts their strength at high temperatures. They showcase a tensile strength of 515 MPa, yield strength of 205 MPa, and an elongation of 40%. The increased carbon content enhances creep resistance and durability at temperatures reaching up to 1100°C. This alloy also excels in resisting corrosion and oxidation, even under cyclic heating and reducing conditions, making it a dependable choice for flanges used in extreme service environments.
