Clad Metal Plate | Roll Bonded

AMETEK Specialty Metal Products has been a leader in developing roll bonding dissimilar metals for more than fifty years. The advantage of clad materials is the end product combines the superior properties of each metal: Strength, Corrosion Resistance, Lightweight, Cost, Thermal and Electrical Conductivity. As a result, clad products produce a material superior to any of the individual metals taken alone.

With competitive price and timely delivery, KLS sincerely hope to be your supplier and partner.

Clad metals produced by our roll bond technology combine two or more metals into a single sheet or plate that can be cut, welded or formed into a finished part ranging from chemical processing chambers and pressure vessels to small applications and clad pipe. We specialize in cladding stainless steel or nickel alloys to carbon steel as well as triple layer clad plates bonding stainless steel to an aluminum core.

Because of the properties offered by clad metals, and the wide variety of cladding and backing materials available today, these metals can be combined to make custom materials for a wide range of demanding industries, including health, chemical and petroleum processing, defense, paper and pulp, food and food processing.

Advantages

If the problem is unique, then the solution could well be a clad metal. In all cases, clad metals provide combinations of properties and advantages not available in monolithic metals such as:

  • Corrosion Resistant Alloys and BPVC rated materials

  • Metallurgically bonded stainless steel and Aluminum

  • Corrosion Resistant and easy cleaning stainless steel cooking surfaces combined with fast heating carbon steel

  • Stainless steel clad with Aluminum core for excellent heat transfer and cooking surface

Manufacturing

AMETEK clad materials are manufactured by roll bonding a core or backing with a specialty metal to produce a metallurgically bonded clad. Many metals can be combined with this technique to provide a custom metal with specific desired properties.

For example, nickel clad steel is an ideal material for withstanding the high-temperature and corrosive environment present in a hospital sterilizer &#; steel provides strength and nickel resists corrosive attack and product contamination.

Materials

Standard composites available are Nickel Clad Steel, Stainless Clad Steel and Stainless Aluminum Clad.

Other materials available include Inconel® Clad Steel, Hastelloy® Clad Steel, 276 Clad Steel, Armor Plate, Copper Clad Steel, Titanium Clad Steel, and Stainless Cladded Tool Steel.

Of course, AMETEK metallurgists are always available to assist you in developing custom product specifications.

Sizes

AMETEKs clad materials are available in standard widths to 120&#; lengths to 480&#; and thickness ranging from 3/16&#; to 1&#;. Cladding on steel backing can be supplied in a range of thicknesses from 5 to 40% of the overall material thickness.

As an additional customer service, we can further process clad plate to meet specifications for close dimensional and flatness tolerances, glass beading or sand blasting one or both sides, cutting to circles or special shapes.

 

Applications

Typical applications include Braising Pans, Boilers, Griddles, Pressure Vessels, Steam Vessels,Cryogenic Transition Plates, and Specialty Knives.

Processing

Roll bonding is achieved by processing a specially prepared &#;sandwich&#; (layers of backing and cladding materials) through a conventional plate hot rolling mill that reduces the thickness and metallurgically bonds the backing steel to the clad material. Parting compound is used between each clad pack before it is welded and then roll bonded to yield two separate clad plates.

After cutting to finish size, the bonded plates are cleaned by blasting with an abrasive mixed with glass beads to obtain a clean, relatively bright surface, both top and bottom, if desired.


Fabrication

Clad plate can be fabricated into different shapes, which allows designers the freedom to produce custom products for a wide range of applications.

Forming: Clad materials can be cut and formed by most shop operations, which include shearing, plasma cutting, drawing, bending, hot forming, machining, drilling and punching.

Welding: Fusing of clad materials is usually done by first welding the backing material using appropriate filler material and then welding the clad side with a welding electrode or filler metal appropriate to that surface.

Quality control, Testing

Generally, clad plate is produced to meet or exceed either ASME A-264 or ASME A-265 codes. To meet these specifications, AMETEK routinely performs tensile tests, shear tests, hardness, bend tests and impact tests (Charpy V-Notch) on modern testing equipment. Other services, as specified by the customer, are also available such as ultrasonic testing, thermal treatment and saw cutting.

Our total quality control begins with our selection of high quality raw materials and follows through to an on-time delivery of the finished product to our customers.

 

Inventory

In order to meet relatively short delivery times, AMETEK maintains an inventory of A-285 Grade C and A-516 Grade 70 carbon steel, nickel 200, and 304L and A-36 stainless steel.

 

We also:

  • Provide a raw material inventory and Just-In-Time stocking programs for high-volume users.

  • Supply small quantities for specialized requirements, and some stock plates that are available upon request.
