Case: High Hardness of CMC-S45H after Being Welded
In June 4th, 2009, our client NanTong Chaoda Machinery and Technology Co., Ltd reflected that CMC-S45H can be used on S45C without any problems. But the series of FCD with a high hardness could become much harder after being rendered by CMC-30N.
In regard of the reflection from NanTong Company, we had collected lots of materials and made several test. Finally, we found TIG welding wire of
CMC-SSH, which was a kind of high hardness welding wire
Could be directly welded on cast steel with good smooth welded melting metal. Immediately, we had made tests on new.
CMC-SSH as following:
1. Shanghai Xinyi Typical Material Melding
Factory (welding, Machinery processing).
Look at the right picture.
2. Shanghai Liyou Metal Industry Co., Ltd ( Rockwell hardness tester).
CMC-SSH 2.4 is welded on FCD400
Hardness degree is HRC: 49~52°
According to those above data, our company suggested our client NanTong Company to choose CMC-SSH to be welded to FCD steel.
Our client was satisfied with the testing results and also had taken our suggestion. After taking CMC-SSH into real molds, our client had given good comment and also received their products users’ appreciation.
