When selecting high temperature resistant materials for threaded inserts, there are many factors to consider, including the material's high temperature stability, mechanical strength, corrosion resistance, and cost. The following is a comparison of several common high temperature resistant materials and their applications in threaded inserts:
1. Stainless steel
Features
High temperature stability: Ability to maintain its mechanical properties in high temperature environments.
Corrosion resistance: Good resistance to most corrosive media.
Mechanical strength: High strength and good ductility.
Applications
Widely used in the chemical, oil and gas industries.
Applicable to medium temperature ranges (approximately below 600°C).
2. Nickel-based alloys
Features
High temperature stability: Ability to maintain strength and stability at extremely high temperatures.
Corrosion resistance: Good resistance to high temperature corrosive media.
Mechanical strength: High strength and good fatigue resistance.
Applications
