Introduction

Hastelloy X, designated as UNS N06002, is a high-performance nickel-based alloy primarily developed for extreme environments involving high temperatures, oxidation, and stress. Produced in multiple product forms—such as rods, sheets, bars, tubes, and plates—Hastelloy X plates are especially prized for their strength, thermal stability, and corrosion resistance in elevated temperature operations. These characteristics make Hastelloy X an essential material in critical components for aerospace engines, gas turbines, heat treatment furnaces, and petrochemical reactors.

This document delivers a complete technical guide on Hastelloy X plates, covering their chemical composition, mechanical and physical properties, fabrication and welding characteristics, applications, corrosion behavior, thermal performance, industry specifications, and commercial considerations.

 Chemical Composition (% by Weight)

 

The alloy's austenitic microstructure contributes to its high ductility and stability even at elevated temperatures above 1000°C.

Room Temperature Properties (Annealed Condition)

 

Physical Properties

Its lower thermal conductivity compared to steels and super-austenitic alloys enables Hastelloy X to act as a thermal barrier material.

Weldability

Hastelloy X is readily weldable using most standard processes, including:

 

• GTAW (TIG)

• GMAW (MIG)

• SMAW (Stick)

• Electron Beam and Laser Welding

Heat-Affected Zone (HAZ)

Weldments exhibit excellent strength, but post-weld heat treatment may be used to relieve residual stress and optimize grain structure, especially in critical applications.
