RO4200-1 RO4210-2 Niobium Tube Pipe ASTM B394-98 Diameter 2mm

Introduction

Niobium tube is a precision pipe designed for transferring materials under extreme conditions, such as high temperature and high pressure. Owing to niobium’s excellent corrosion resistance and thermal stability, niobium tubes demonstrate outstanding compressive strength, tensile strength, fatigue resistance, and heat resistance.

These properties make niobium tubing ideal for applications in the nuclear industry, aerospace, shipbuilding, chemical engineering, and electronic equipment manufacturing.

Chemical Composition

Surface Treatment

Niobium tubes can undergo various surface treatment processes to enhance corrosion resistance and improve appearance:

Mechanical Polishing: Improves surface smoothness and dimensional accuracy.

Electrolytic Polishing: Produces a bright, corrosion-resistant finish.

Pickling: Removes oxide scales, oil, and surface contaminants.

Sandblasting: Cleans and textures the surface for subsequent processing or coating.

Applications

Niobium and its alloys are highly valued across multiple industries for their exceptional mechanical and chemical properties. Niobium tubes are widely used in:

1. High-temperature alloys and superalloys

2. Niobium-based alloys for heat and corrosion resistance

3. The steel industry as alloy additives to improve toughness and creep resistance

4. Electrical and electronic components

5. Precision instruments and optical devices

6. The medical field, including surgical implants and imaging systems

7. Aerospace and defence applications
