Systems and methods for production of metallurgically bonded clad billet and products thereof, and metallurgically bonded clad billet

A method of producing a clad billet, comprising:

• providing a corrosion resistant alloy cylinder, the corrosion resistant alloy cylinder including a hollow interior, an inner diameter, and an outer diameter,
• inserting a solid carbon or low-alloy steel material into the hollow interior of the corrosion resistant alloy cylinder so that an outer surface of the solid carbon or low-alloy steel material faces the inner diameter of the corrosion resistant alloy cylinder, and so that a concentric standoff gap is provided between the outer surface of the solid carbon or low-alloy steel material and the inner diameter of the corrosion resistant alloy cylinder;
• providing an explosive material around the outer diameter of the corrosion resistant alloy cylinder;
• detonating the explosive material to collapse at least the inner diameter of the corrosion resistant alloy cylinder onto the outer surface of the solid carbon or low-alloy steel material and eliminate the standoff gap, creating a partial metallurgical bond at an interface with the outer surface and resulting in a composite billet assembly;
• welding each opposite end of the composite billet assembly at the interface to create a seal against oxidation of the interface;
• and
• extruding the composite billet assembly to reduce the size of the composite billet assembly by reducing a thickness of each of the corrosion resistant alloy cylinder and the solid carbon or low-alloy steel material and form the clad billet having a 100% metallurgical bond between the solid carbon or low-alloy steel material and the corrosion resistant alloy cylinder.
