Heat Treatment Equipment Field Incoloy Alloy 800H Tube 600 MPa Tensile Strength Cold Rolling Hot Rolling

Product Introduction

Incoloy Alloy 800H tube has a wide range of applications in the field of heat treatment equipment, mainly due to its excellent high temperature performance and corrosion resistance. This alloy tube can work stably for a long time at temperatures up to 1100°F (about 593°C), and has excellent creep resistance and oxidation resistance, making it an ideal material for high temperature industrial environments. The main chemical composition of Incoloy 800H includes 30-35% nickel (Ni), 19-23% chromium (Cr), and the balance of iron (Fe), which gives it excellent oxidation and corrosion resistance at high temperatures. Its physical properties include density 8.14 g/cm³, melting point 1343℃, tensile strength of at least 765 MPa, yield strength of at least 350 MPa, and elongation of at least 30%. These characteristics make Incoloy 800H tube an ideal choice for manufacturing components such as furnace linings and heating elements in heat treatment equipment, ensuring stable and reliable operation of the equipment at high temperatures. In addition, Incoloy 800H has good processing performance and can be formed by conventional welding, cold rolling, hot rolling and other processes, making it suitable for manufacturing parts with complex structures. In heat treatment equipment, such as annealing furnaces and quenching furnaces, Incoloy 800H can withstand high temperatures and frequent thermal cycles and maintain good performance.
