production Description
Medium chromium grind forging is a metal material with medium chromium content, its properties are between cast steel forging and high chromium forging. chromium forging has good wear resistance, corrosion resistance and toughness, is suitable for some occasions that do not require high material properties. The advantage of chromium forging in is that its manufacturing cost is relatively low, processing difficulty is less, can meet the manufacturing needs of some common mechanical parts and structures. , however, the disadvantage of chromium forging is that its performance is relatively mediocre, not as good as high chromium forging and casting steel forging in some special cases. In addition, the corrosion resistance of chromium forging is not as good as high chromium forging, need to pay attention to the use of some strong acid, strong alkali and other extreme environment.

Our advantage
The medium chromium grinding and forging materials have reached an ideal balance point between wear resistance and economy. Compared with high chromium forging, medium chromium grinding forging not only ensures sufficient wear resistance, but also reduces the manufacturing cost , enables customers to obtain quality products at the same time, can also enjoy a more affordable price. This material is suitable for medium load and wear ball mill applications, is a cost-effective choice. chromium grinding forging has good wear resistance, corrosion resistance and toughness, is suitable for some occasions that do not require high material properties. Compared with high chromium forging, the manufacturing cost of chromium grinding forging is relatively low, processing difficulty is less, can meet the manufacturing needs of some common mechanical parts and structures. Although its performance is relatively mediocre, is not as good as high chromium forging in some special situations, in many applications medium chromium grinding provides an economical and effective solution.
