Thanks to a unique process combining an online forging press and a specific rolling mill, Bozhong can supply forged grades.
The advantages of this unique process are:
1.Adjusted chemical composition while respecting the standards required in order to get improved weldability
2.Very good compactness through thickness controlled by UT
3.Excellent through thickness Z properties
4.Flat products with a good surface aspect (descaled, ground, shot blasted)
5.Gain of machining (compared to regular forged products).
6.Excellent machinability of tube-holes thanks to homogeneous properties and structure through the entire thickness
