Home > Incoloy > Incoloy 825 Tubing
High-performance Incoloy 825 tubing is available from Vipul Pipes and Tubes, a top manufacturer and supplier in Chennai, India, for use in extremely corrosive and hot conditions. With molybdenum, copper, and titanium added, Incoloy 825 is a nickel-iron-chromium alloy that is incredibly resistant to oxidation and acid attacks. Our seamless and welded tubing is produced in accordance with stringent quality standards (including ASTM B423 and ASME SB-423). For applications where dependability and corrosion resistance are crucial, such as chemical processing, pollution control, nuclear fuel reprocessing, and marine exhaust systems, Incoloy 825 tubing is perfect.
Nickel (38–46%), iron (balance), chromium (19.5–23.5%), molybdenum (2.5–3.5%), copper (1.5–3%), and titanium (0.6–1.2%) are the usual elements found in Incoloy 825 tubing. This alloy has outstanding resistance to pitting, stress corrosion cracking, crevice corrosion, and sulfuric and phosphoric acids. The tubing has good elongation and toughness even at high temperatures, with a tensile strength of about 585 MPa and a yield strength of about 220 MPa. It is a dependable material for harsh chemical and thermal environments because it is stable and retains its mechanical integrity up to 540°C.
