发明名称 Methods of producing high-strength metal tubular bars possessing improved cold formability
摘要 A method for producing a tubular bar, more particularly a stabilizer bar, is provided. The method comprises providing a tubular bar of desired size having an outer and inner surface, heating the bar to an elevated temperature, quenching the bar by application of a cooling fluid to the surfaces of the bar, and forming the tube to a desired shape without annealing. The method further provides for the composition of a high-strength, high formability carbon steel alloy to be used in conjunction with the method. Advantageously, the bar is formable without thermal processing subsequent to quenching. In this fashion, metal tubular bars, such as stabilizer bars, may be formed at reduced cost.
