MO-RE 2 vs HK40 vs Inconel 601/800 Heat Resistant Alloy Comparison

Overview
In industrial furnace and high-temperature applications, MO-RE 2, HK40, and Inconel 601/800 are commonly used heat resistant materials for tubes, bushings, and structural components.
However, these materials belong to different alloy systems:

• MO-RE 2 → Ni-Cr-W cast alloy (MO-RE series)
  
• HK40 → Fe-Ni-Cr heat resistant cast steel
  
• Inconel 601/800 → Nickel-based wrought alloys
  

Each material has different performance, cost, and application range.

Quick Comparison Table

Material Explanation
What is MO-RE 2?
MO-RE 2 is a Ni-Cr-W based heat resistant cast alloy, widely used in furnace tubes and bushings. It is designed for high temperature strength and long service life.
What is HK40?
HK40 is a Fe-Ni-Cr heat resistant cast steel, commonly used in lower cost furnace applications but with lower creep resistance compared to nickel-based alloys.
What is Inconel 601 / 800?
Inconel 601 and 800 are nickel-based wrought alloys with excellent oxidation resistance and high temperature stability, widely used in severe environments.

Important clarification

• MO-RE 2 ≠ Mo-Re refractory metal
  
• HK40 ≠ nickel alloy
  
• Inconel ≠ cast furnace alloy (usually wrought)
