Ductile iron was added to improve performance rare earth

- Jan 20, 2021-

In the aspect of high-strength low-alloy ductile iron, in addition to copper and molybdenum, nickel and niobium are also studied. Although the performance of medium manganese ductile iron is not stable enough, many years of systematic research and production applications have achieved significant economic benefits. In terms of acid-resistant ductile iron, the rare earth high silicon ductile iron produced in China has a finer, uniform and dense structure than ordinary high silicon cast iron. As a result, the corrosion resistance is increased by 10% to 90% , and its mechanical strength is also significantly improved.
