Photo1(Domestic). carbon carbide size Obvious appear big size.
Photo2 (abroad) the carbide distribution is uneven and the individual is large.Reason analysis: during the smelting process, the carbide can not be controlled well. In the late forging, although the forging ratio increases, it fails to make up for the defects of the smelting.

Photo1(domestic), the carbide individual is obviously large, the processing will appear the phenomenon of detachment.
Photo2(abroad),The carbides are superior to domestic ones, but there are more angular carbide, and cracks and stress concentrations are easy to occur in use, leading to early failure.
Photo3(ZhengDa=Zeicin) the modification of 9Cr18Mo in the process of smelting and forging, the level of carbide is obviously superior to the imports.

Photo1(domestic), Zonal carbides are obvious, the carbide particles are obviously larger than the longitudinal ones, cause analysis: no make modified forging, Just make rolling directly.
Photo2(abroad) the distribution of carbides is not uniform and the individual is large. Reason analysis: during the smelting process, the carbide can not be controlled well. In the late forging, although the forging ratio increases, it fails to make up for the defects of the smelting.

Martensite stainless steel: 마르텐사이트 스테인레스
The advantages of choosing 9Cr14MoV+Co:
1) It is not easy to break when it is used for warping bending shear;
2) The matrix strength is higher;
3) The toughness is better
For example: one of our representative clients
This company produces for Satellite bearing, which are very influential in China.
http://www.zysbearing.com/
This company is a military enterprise, specializing in the manufacture bear for rockets, satellites etc.. Below test report is from this customer to provice.
