MO-RE 1 vs MO-RE 2 Heat Resistant Alloy (NiCrW Furnace Tube Comparison)
🟩 Overview
MORE 1 and MO-RE 2 are both Ni-Cr-W based heat resistant cast alloys widely used in industrial furnace systems.
They are trade designations used in the furnace and casting industry, not standard international alloy grades.
Both materials are manufactured using centrifugal casting technology for furnace tubes, bushings, rollers, and structural components.
👉 MO-RE 2 is generally considered a higher-performance version compared to MORE 1, especially in high-temperature strength and oxidation resistance.

🟥 Material Definition
What is MORE 1 material?
MORE 1 is a commercial furnace alloy designation, typically referring to:
Ni-Cr-W heat resistant cast alloy (standard grade)
What is MO-RE 2 material?
MO-RE 2 is also a Ni-Cr-W heat resistant cast alloy, but with:
- Higher tungsten strengthening
- Improved creep resistance
- Better oxidation resistance
❌ Important clarification
Neither MORE 1 nor MO-RE 2 are:
- ❌ Molybdenum-Rhenium (Mo-Re) alloys
- ❌ Refractory metal systems
- ❌ Steel grades
They are nickel-based heat resistant casting alloys used in furnace industry.
