Abstract:
A method of making a seamless, tubular article comprises subjecting a cast tubular workpiece of a corrosion resistant alloy to at least about a 25% wall reduction at a temperature below a recrystallization temperature of the workpiece using a metal forming process comprising at least one of radial forging, rolling, pilgering, and flowforming. The cast tubular workpiece is a centrifugally cast tubular workpiece comprising an inner diameter and an outer diameter.
