Характеристики



GCr15


Product application
GCr15 is the most commonly used high chromium bearing steel. Used for bearing sleeves, steel balls, and rollers of grades H to C, it can be used for bearing large loads,other mechanical parts that require high wear resistance, high elastic limit, and high contact fatigue strength, as well as various precision measuring tools.
