Embodiment Construction
[0023] The test material is selected on the basis of the chemical composition standard of 0Cr13 ferritic stainless steel, and 0.20-0.50% Mo is added to optimize the content of C, Cr, Ni, N and other elements. The chemical composition used is shown in Table 2. The experimental material except Mo Other ingredients are the same as the prior art. In the above list, serial numbers 3# to 6# are embodiments of the present invention, and serial numbers 1# and 2# are steel grades in the prior art. Serial number 1# is the common chemical composition of 0Cr13 stainless steel produced in industry, and serial number 2# has higher Cr content and lower C content, which is a chemical composition with higher corrosion resistance. The room-temperature mechanical performance comparison table of the embodiment and the prior art is shown in Table 3. It can be seen that embrittlement phenomenon has occurred in serial number 2#, therefore, C should not be too low and Cr should not be too high; Examp...
