The excellent corrosion resistance and mechanical properties of the 12Cr9NiAlMoprealloy makes itself has high application value.
The morphology as shown below：
According to the research of AM center in Canadian New Brunswick University, the chemical content of CX powder used in SLM process is shown in Table1:
Table1. chemical content of CX powder
Element | Fe | Cr | Ni | Mo | Al | Mn | Si | C |
Weight(%) | Balance | 11-13 | 8.4-10 | 1.1-1.7 | 1.2-2 | 0.40 | 0.40 | 0.05 |
According to the research, using the parameters in table2, the Hardness of the printed component could reach 35±1HRC，Yield strength is 1036MPa and Elongation is 21.7%。
