Abstract
An elongated hollow component includes a body extending from a first end to a second end and defining a longitudinal axis. The body includes a plurality of layers each circumscribing the longitudinal axis. The plurality of layers includes a base layer including a first steel material, and an inner surface coating coupled to a radially inner surface of the base layer. The inner surface coating includes a second steel material.

A method of fabricating an elongated hollow component, said method comprising:
- unrolling a sheet of a first steel material from a coil as a sheet;
- coupling an inner surface layer to the unrolled sheet to form a plurality of layers, wherein a base layer is formed from the first steel material and the inner surface layer is formed from a second steel material;
- stamping, after said coupling the inner surface layer, the base layer to cut the base layer from the coil;
- and
- rolling, after said stamping the base layer, the plurality of layers to form a tubular body of the elongated hollow component, such that the plurality of layers each circumscribe a longitudinal axis extending from a first end to a second end of the body, and the inner surface layer is on a radially inner surface of the base layer and exposed to an interior cavity of the hollow component.
