Zr Ti Steel Clad Plate

Zr Ti Steel Clad Plate

The zirconium/titanium/steel clad plate is a multi-layer composite material typically made by bonding zirconium, titanium, and carbon steel or stainless steel through explosive welding. Zirconium, known for its exceptional corrosion resistance and good machinability, is well-suited for applications such as pressure vessel shells, heat exchanger tube sheets, tower components, and piping. However, using pure zirconium for pressure vessels is expensive and inefficient, often resulting in resource waste. Therefore, it is commonly combined with steel to optimize both cost and material usage.

Direct bonding of zirconium and steel can lead to brittle intermetallic compounds that weaken the bond, so an intermediate layer is used to improve strength. A commercially pure titanium sheet (usually 2-3 mm thick) serves as this transition layer, creating a three-layer clad plate: zirconium-titanium-steel. This clad plate combines the corrosion resistance (resistant to strong acids and alkalis) and radiation tolerance of zirconium with the strength and cost advantages of the steel base, making it ideal for use in the chemical industry, nuclear sector, marine engineering, and medical fields where high corrosion resistance and strength are critical.

	Clad Layer THX.	TTL THX.	Max. Width	Max. Length
Explosive	min. 2mm	–	4.5m	14m
Explosive + Rolling	0.8-2mm	max. 152mm	4.5m	14m
Rolling	0.8-14mm	8-40mm	4.5m	14m

Thickness ratio of the cladding to the base material should be greater than or equal to 1:3 for roll bonding.

We can produce wide titanium-steel clad plates using a 5-meter rolling mill, ensuring the cladding layer is seamless.

Others could be tailored due to customer’s unique need.

characteristics

Different composite methods have varying requirements for the cladding and base materials. We can provide customized production based on the specific needs of our customers.

DELIVERY AND PACKING

Below is our standard packing method for export transportation, for other special requirements from our customers, we can customize. The surface of the clad plates is covered with a PE plastic film, followed by a layer of hard cardboard for protection. The outermost layer is waterproofed, and labels are applied to ensure effective identification. The product is then loaded for shipment.

FAQ

Can customers specify the suppliers of raw materials such as pressure vessel steel, stainless steel, titanium, copper, and nickel-based alloys used in CLAD products when placing an order?

Of course, no problem. Our company has long-standing, strong partnerships with major steel mills such as TISCO, TSINGSHAN, Jinan Steel, CITIC Special Steel, NISCO, ANSTEEL, SHOUGANG, and SHAGANG, as well as suppliers of titanium, nickel alloys, and copper materials. Customers can specify their suppliers or provide their own raw materials.

Can we include our own specific requirements and agreements in addition to the general ordering terms?

Yes, it is certainly possible to include your own specific requirements and agreements alongside the standard ordering terms. This can be done through a customized agreement or contract that outlines any additional specifications, terms, or conditions unique to your order. It is essential that both parties reach mutual agreement on these additional terms before proceeding with the order to ensure clarity and alignment.

Can the customer request third-party inspection and a 3.2 certificate of compliance?

Yes, customers can request third-party inspection and the issuance of a 3.2 certificate of compliance. This certificate, which verifies that the product meets specific quality standards, can be provided upon request. The third-party inspection will be conducted by a recognized independent entity to ensure that the product complies with the agreed-upon specifications. Please inform us in advance if this is required, so we can make the necessary arrangements.

Does the company maintain a regular stock of cladded plates for quick delivery?

Due to the specific nature of cladded plates, each order is typically accompanied by a technical agreement, making it difficult for us to keep a large inventory. However, we do maintain some stock of certain grades of cladded plates. Feel free to inquire with us about availability.

What is the typical delivery time for your company’s cladded plates?

The delivery time depends on the arrival of base materials and cladding materials. If there are no special technical requirements, both rolling and explosion bonding processes can typically be completed and delivered within 25-35 days after the raw materials arrive.
