What Industries Are Tantalum-Steel Composite Plates Mainly Used In?​

Tantalum-steel composite plates, also known as tantalum clad plates, are engineered materials that combine the superior corrosion resistance of tantalum with the structural strength of steel. This synergy results in a material capable of withstanding extreme environments, making it indispensable across various high-demand industries.​

What Are the Advantages of Using Tantalum-Steel Composite Plates Compared to Other Materials?
Tantalum-steel composite plates offer a unique combination of properties that set them apart from other materials:​

Exceptional Corrosion Resistance: Tantalum exhibits remarkable resistance to a wide range of corrosive environments, including strong acids like hydrochloric, sulfuric, and nitric acids. This makes tantalum-steel composites ideal for applications in chemical processing industries. ​

High-Temperature Stability: With a melting point of approximately 3,017°C, tantalum maintains its structural integrity at elevated temperatures, making it suitable for high-temperature applications such as aerospace components and heat exchangers. ​

Mechanical Strength: The steel substrate provides the necessary mechanical strength and structural support, allowing the composite plate to withstand mechanical stresses while benefiting from the corrosion resistance of tantalum.​

Cost-Effectiveness: By cladding a thin layer of tantalum onto a steel substrate, manufacturers can achieve the desired corrosion resistance at a fraction of the cost of using solid tantalum components.​

What Are the Technical Specifications and Standards for Tantalum-Steel Composite Plates?
Tantalum-steel composite plates are manufactured to meet specific technical standards to ensure their performance and reliability:​

Base Material: Commonly used steel grades include SA-516 Gr.70 or SA-285 Gr.C, providing the necessary mechanical strength.​

Cladding Material: Tantalum Grade ASTM B708 R05200 is typically used for the cladding, offering high purity (≥99.9%) and excellent corrosion resistance.​

Thickness: Steel substrate thickness ranges from 6mm to 50mm, while the tantalum cladding thickness typically ranges from 0.5mm to 3mm.​

Bond Strength: The bond between the tantalum and steel layers must meet or exceed 140 MPa, ensuring structural integrity under operational conditions.​

Testing Requirements: Comprehensive testing, including ultrasonic testing of the bond area, dye penetrant testing of exposed edges, bend tests, and shear tests, are conducted to ensure quality and performance. ​
