With a robust infrastructure and a skilled workforce, Harsh Metalloys guarantees consistent quality, timely deliveries, and complete customer satisfaction. Our Stainless Steel 310H Flanges find applications in various industries, including petrochemical, power generation, and thermal processing, catering to clients both in India and around the globe.
Stainless Steel 310H Flanges are crafted from a high-carbon variant of 310 stainless steel, which enhances their strength at elevated temperatures. The composition features 24–26% chromium, 19–22% nickel, and a carbon content of up to 0.10%. This alloy is known for its excellent oxidation and creep resistance, even at temperatures reaching 1100°C. In terms of mechanical properties, these flanges have a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. They come in various types, including weld neck, slip-on, socket weld, and blind, all conforming to ASTM A182 standards and other international specifications.
