Hastelloy X(UNS  N06002 W.Nr. 2.4665)

1.HASTELLOY X INTRODUCTION

A nickel-chromium-iron-molybdenum alloy with  outstanding strength and oxidation resistance  at temperatures to 2200°F (1200°C). Matrix  stiffening provided by the molybdenum content  results in high strength in a solid-solution alloy  having good fabrication characteristics. Used in  gas turbines, industrial furnaces, heat-treating  equipment and nuclear engineering.

2.HASTELLOY X  STANDARD  PRODUCT FORMS

Sheet, strip, plate, round bar, flat bar, forging stock,  hexagon, wire and extruded section.
