Titanium Clad Steel Plate

Titanium clad steel plate is a laminated composite material made by bonding titanium plates onto carbon steel substrates.

It combines:

Titanium: excellent corrosion resistance

Steel: high structural strength + low cost

Result: a cost-effective corrosion-resistant structural solution

CORE VALUE

Pure titanium is highly corrosion-resistant but expensive.
Titanium clad steel provides an optimal balance of performance and economy, significantly reducing material cost in large-scale industrial applications.

MANUFACTURING METHODS

Explosive bonding (explosive cladding)

Hot rolling composite bonding

Modern production increasingly uses hot rolling technology for improved efficiency and consistency.

MATERIAL STRUCTURE

Top layer: Titanium (corrosion protection layer)

Base layer: Carbon steel (structural support)

Interlayer control is critical to prevent brittle phases such as:

TiFe

TiFe₂

To avoid embrittlement:

Ultra-low carbon steel interlayer (<50 ppm C) is used

Control of diffusion and bonding temperature is essential

PROCESSING TEMPERATURE

Optimal rolling temperature: ~850°C

Controlled thermal bonding for interface stability

KEY PERFORMANCE ADVANTAGES

Excellent corrosion resistance (titanium surface)

High mechanical strength (steel base)

High stiffness and durability

Strong plastic toughness

Significant cost reduction vs solid titanium

APPLICATIONS

Power & Energy

Power plant chimneys

Flue gas desulfurization systems (FGD)

Heat exchanger systems

Chemical Industry

Reactor vessels

Pressure vessels

Corrosion-resistant tanks

Process equipment linings

Thermal Systems

Heat exchangers

Condensers

Industrial cooling systems

FABRICATION GUIDELINES

1. Heat Treatment

Stress relief annealing required when plasticity is reduced

2. Forming

Preheating required for low-temperature bending

Prevent cracking or blistering during deformation

3. Machining

Prefer processing from titanium side to steel side

Prevent delamination or edge cracking

4. Welding

Use ≥99.99% pure argon shielding gas

No contamination allowed in weld zone

Strict surface cleaning required before welding

5. Composite Welding Method

Steel layer welded first

Titanium layer welded using argon protection

Edge sealing with titanium strip overlay (~50 mm coverage)

6. Defect Handling

Large defects → material replacement

Small defects → repair welding or rivet reinforcement

Surface micro-cracks must be cleaned and repaired

ENGINEERING BENEFITS

Extends equipment life in corrosive environments

Reduces total lifecycle cost

Maintains structural integrity under pressure and heat

Enables large-scale titanium application at lower cost

INDUSTRIAL POSITIONING

Titanium clad steel is the ideal solution for combining "corrosion resistance of titanium" with "strength and economy of carbon steel."

SUMMARY

A premium composite engineering material designed for chemical, energy, and industrial corrosion environments, delivering high performance at optimized cost efficiency.
