Mechanical Properties of Monel Tube
Tensile Strength
Tensile strength represents the maximum stress a monel tube can withstand before failure. Monel tubes provide high tensile strength and excellent durability, making them suitable for marine, offshore and chemical processing applications.
Yield Strength
Yield strength indicates the stress level at which permanent deformation begins. Monel tubes maintain excellent yield strength, ensuring reliable performance in corrosive and high-pressure environments.
Elongation
Elongation measures the ductility and flexibility of monel tubes before fracture. High elongation improves fabrication and installation performance in industrial tubing systems.
| Grade | Tensile Strength (MPa, Min) | Yield Strength (MPa, Min) | Elongation (% Min) |
|---|---|---|---|
| Monel 400 | 550 | 240 | 35% |
| Monel K500 | 965 | 690 | 20% |
