Hot Forging Steel Ball
Hot Forging Steel Ball have unique size, round geometry, excessive hardness and desirable mechanical houses, and have high-quality great of wear and tear resistance, no deformation and no cracking. its characteristics are as follows:
1. high typical hardness: the floor hardness can attain fifty eight-65hrc, the extent hardness can reach 55-62hrc, and the hardness gradient distribution is uniform;
2. excessive effect toughness: the impact toughness is more than 12j / cm2;
3. low crushing charge: the anti stripping and anti crushing performance is more than 10 instances that of everyday solid and forged metal balls, the impact times of falling balls are more than 20000, and the real crushing rate isn't greater than 1%, that's close to no crushing.
Shandong jinchi heavy company co., ltd. is a modern-day-day manufacturing business enterprise integrating r & d, manufacturing and sales! Hot Forging Steel Ball of the employer are put on-resistant metal balls, placed on-resistant steel rods, put on-resistant steel forgings, mill lining plates, metal systems, and mine accessories. great creates emblem and excellent creates blessings; advanced manipulate concepts, state-of-the-art procedure machine, and notable workforce have implemented an appropriate first rate appeal in every link of the production way, and realized the whole upgrading of product excellent.
