Stainless steel composite plate for pressure vessels

Stainless Steel Composite Plate for Pressure Vessels

Product Introduction

The Stainless Steel Composite Plate for Pressure Vessels is an advanced material designed for use in demanding environments such as chemical processing, energy generation, and high-pressure systems. This product combines the durability and strength of stainless steel with the corrosion resistance and thermal conductivity of composite materials, making it an ideal choice for pressure vessels that require long-lasting performance under extreme conditions.

Base layer (carbon steel or alloy steel): Provides mechanical strength and pressure-bearing capacity.

Cladding layer (stainless steel): Ensures corrosion resistance, oxidation resistance, and protection against aggressive media.

This unique combination makes stainless steel composite plates highly suitable for fabricating pressure vessels that are exposed to high pressures, harsh environments, and corrosive substances.

Manufacturing Process of Stainless Steel Composite Plate

1. Explosion Welding

Explosion welding is a high-energy process where stainless steel and carbon steel plates are bonded under the action of controlled explosive force. This results in a strong metallurgical bond without melting the base materials, ensuring excellent mechanical integrity.

Advantages:

Strong bonding strength

No heat-affected zone issues

Suitable for large plate sizes

2. Hot Rolling Bonding

In hot rolling, stainless steel and carbon steel are heated together and rolled under high pressure. This process creates a uniform and reliable bond between the two metals.

Advantages:

Good surface flatness

Stable composite structure

Applicable for mass production

Technical Specifications

Advantages of stainless steel clad plates for pressure vessels

• High bonding strength – Tensile shear strength usually exceeds industry standards, ensuring structural safety.
• Excellent corrosion resistance – The stainless steel cladding layer resists acids, alkalis, chlorides, and seawater.
• Mechanical performance – The carbon steel base provides superior yield strength and impact resistance.
• Thickness flexibility – Cladding thickness can range from 2mm to 10mm, depending on application needs.
• Weldability – Both base and cladding layers can be welded using appropriate filler metals and techniques.​​​​​​​
