11.509mm(0.45311"), G10, G16, G20, High Quality Chrome Steel Ball for bearing, GCr15
GCr15 Features
GCr15 steel is a representative steel grade of high-carbon chromium bearing steel with good overall performance. good cutting performance after spheroidizing annealing, high and uniform hardness after quenching and tempering, high wear resistance and contact fatigue strength, and good thermal processing performance. Good overall performance, Contains more alloying elements and is cheaper. GCr15 steel is the most used and produced high carbon chromium bearing steel, and is widely used in the world. However, it has strong white spot sensitivity, poor welding performance, high and uniform hardness, and good wear resistance. Used to make small cross-section quenched and tempered parts with larger load and large normalized parts with less stress. Mainly used in the manufacture of steel balls, rollers and bushings on drive shafts such as internal combustion engines, electric locomotives, machine tools, tractors, steel rolling equipment, drilling rigs, railway vehicles and mining machinery.
Chrome steel and other metal balls are manufactured using the following processes
- Forging and cold heading. Rough ball shapes are forged from bar stock material.
- Deflashing. Rough machining or soft grinding removes the forge flashing.
- Heat treatment. Balls are heat treated based on technical specifications in a controlled process.
- Finishing. Stainless steel balls skip this step. Other steel balls may be hardened using heat treatments, quenching, or other tempering methods.
- Hard Grinding. The steel balls are ground to remove nicks and imperfections.
- Lapping. A controlled mechanical sanding/polishing process brings the balls into the intended design, grade dimensions, and spherical accuracy within 1/1,000,000 of an inch.
- Inspection & Packaging. Lubricant or rust-preventive is applied as a final step before the steel balls are inspected and packaged.
