LOW-CARBON CHROMIUM STEEL HAVING REDUCED VANADIUM AND HIGH CORROSION RESISTANCE, AND METHODS OF MANUFACTURING
摘要:
Embodiments of the present disclosure are direct to a low-carbon chromium steel, and methods for manufacturing said steel, having a low vanadium concentration. In some embodiments, the steel can have high corrosion resistance while retaining adequate strength and toughness. The steel can be manufactured through an austenitization process, followed by quenching at a controlled cooling rate, and tempering to form about 5 to 10% bainite, while limiting formation of chromium rich carbides.
