Product Advantages
1.Excellent Internal Organization Structure
After forging procedure and hot working, the internal structure of steel ball has been deformed
and recrystallized, which makes the internal structure become more and more tightly. As a result, the
forging part has an excellent internal organization structure and improve its property greatly.
2.Outstanding Mechanical Property.
Since the forging process guarantees the continuity of the metal fiber organization, the internal
organization of manhole cover brings into correspondence with its appearance. Consequently,
the metal flow is quite complete. And this makes the forging part has an outstanding mechanical
property and also a long usage life.
3.Cost effective and economically.
Through forging procedure, the shape of manhole cover is very close to the finished product. Thus
there is little machining allowance left. And this reduces its processing cost and makes it very cost
effective.
4.Widespread usage.
Because the forging parts have lots of advantages, they are widely used in the metallurgy, mining,
machinery, chemical, auto, aviation, and ship hardware and so on.
