Model: Hastelloy N (UNS N10003)
Handelsmerk: Ronsco


Overview of Hastelloy N:

Hastelloy N is a nickel-based high-temperature alloy composed of nickel, molybdenum, chromium and other elements, with a nickel content of about 72%. Hastelloy N has good oxidation resistance, and the melting point temperature range is 1300~1600°F (704 to 871°C). In more than two years, the N value of Hastelloy N will involve the most useful fluoride in high-temperature environments. Hastelloy N has good oxidation resistance in the air. The metallographic examination shows that the elements in alloy N remain in the range of 1100 to 1600° in the solid solution, and the tensile test has no tendency to embrittlement.

Hastelloy N has good weldability and can be welded easily. The alloy's thermal working range is 1600 and 2150°F (871 to 1177°C), and it has been successfully extruded and further processed into high-quality seamless steel pipe manufacturing, welded and stretched pipes. After solution heat treatment, Hastelloy N alloy parts can be hot-worked or cold-worked.

The specifications and supply status of Hastelloy N:

1. Variety classification: various specifications of seamless pipes, welded pipes, plates, bars, forgings, rings, wires and matching welding materials can be supplied.

2. Delivery status: seamless pipe: solid solution + acid white, length can be set; plate: solid solution, pickling, trimming; welded pipe: solid solution acid white + RT% flaw detection, forging: annealing + car polish; Bars are forged and rolled, surface polished or car polished; strips are delivered after cold rolling, solid solution soft state, and deoxidized; wire rods are finely ground in solid solution pickled disk or straight strips, solid solution straight strips Delivery in light state.
