Features: 440C steel balls are spherical parts made of high carbon high chromium martensitic stainless steel. Their characteristics fully rely on the core performance of 440C steel and combine with the application scenarios of the "spherical shape" (such as bearings, grinding, precision transmission, etc.), forming three core advantages: "hardness, wear resistance, and rust resistance."
Applications: 440C steel balls are mainly used in scenarios with medium to low corrosion, medium temperature, and high requirements for hardness, wear resistance, operational accuracy, and service life, such as precision bearings (for motors, machine tools, automobiles), small fine grinding equipment, precision valve cores, and medical device transmission components.
