isothermal quenching

The gradient hardening forged steel balls developed by China have achieved a double breakthrough in terms of hardness (65HRC) and toughness (18J/cm²), with a 50% increase in lifespan. Using the 42CrMoV alloy and post-forging residual heat quenching process, the single consumption of 80mm steel balls is 0.45kg/t of raw ore. They have been certified by BHP Billiton and the first 2,000 tons of orders will be used for the iron ore project in Australia. This technology fills the international gap and is planned to have a 35% market share in the high-end market by 2026.
