S32205 Duplex Stainless Steel Clad Plate

S32205 Duplex Stainless Steel Clad Plate

The 2205 duplex stainless steel clad plate is composed of 2205 duplex stainless steel combined with carbon steel, low-alloy steel, or line pipe steel. It combines the excellent corrosion resistance of 2205 duplex steel with the strength and cost-effectiveness of the carbon steel base layer, making it ideal for applications in industries such as oil and gas, chemical processing, and marine engineering, where high strength and corrosion resistance are critical.

2205 duplex stainless steel, with its high chromium and molybdenum content, provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in seawater and chloride environments. Additionally, its yield strength is approximately twice that of austenitic stainless steel, offering excellent fatigue resistance and suitability for high-strength applications.

The base material—such as carbon steel, or X65 or X70 line pipe steel—offers robust structural support and significant cost advantages. Manufacturing methods like explosion welding and hot rolling are commonly used to create a high-strength, stable bond. The 2205 duplex steel clad plate is widely applied in oil and gas pipelines, chemical storage tanks, heat exchangers, and marine structures, providing an economical and durable material solution for challenging environments.

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.
