| 发明名称 | Method of producing cold-worked centrifugal cast tubular products | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method of making a seamless, tubular article, the method comprising: subjecting a cast tubular workpiece of a corrosion resistant alloy to at least a 35% wall reduction including at least two reductions 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, and wherein a first reduction applied to the cast tubular workpiece is at least a 25% wall reduction; wherein the cast tubular workpiece is a centrifugally cast tubular workpiece comprising an inner diameter and an outer diameter. | ||
