1. Material Composition

2. Mechanical Properties

• Tensile Strength: 450–600 MPa

• Yield Strength: ≥280 MPa

• Elongation: ≥20% (dependent on wall thickness)

• Impact Toughness: Complies with EN 10216-2 requirements for elevated temperature resilience.

3. FAQ: EN 10216-2 10CrMo9-10 Seamless Steel Tubes

(1). What testing is required for compliance?

• Hydrostatic testing: Verifies leak-tightness.
• NDT: Ultrasonic or eddy current testing for defects.
• Mechanical/chemical tests: Validate composition and properties.

(2). What's the Manufacturing Process?

• Seamless Tube Production:

Hot Extrusion: Heated billets forced through a die to form hollow shells.

Rotary Piercing: Billets rotated and pierced by a mandrel to create seamless tubes.

Cold Drawing: Optional for tighter dimensional tolerances and smoother surfaces.

• Heat Treatment:

Normalizing: Heated to 890–950°C, air-cooled to refine grain structure.

Tempering: Reheated to 680–730°C, followed by air cooling to balance strength and ductility.

(3). What is the application?

• Power Plants:

Superheaters/Reheaters: Operate at 540–580°C, 150–250 bar.

Steam Pipelines: Transport high-energy steam to turbines.

• Petrochemical:

Catalyst Tubes: In reformers, handling hydrogen at 500–600°C.

Heat Exchangers: For hydrocarbon processing.
