Product Description
304BQ comprehensively adjusts the content of Cu, Si and other components on the basis of 304 steel, improves the work hardening characteristics of the material, and enhances the deep drawing performance. Annealing technology is often specially treated, mainly suitable for industries such as water tanks, household appliances, and beer barrels
| Steel grade | C(%) | Si(%) | Mn(%) | Ni (%) | Cr (%) | Cu(%) | MD30(℃) |
| General 304 | 0~0.08 | 0~1.0 | 0~2.0 | 8.0~11.0 | 18.0~20.0 | - | - |
| 304BQ | 0.04~0.07 | 0.3~0.6 | 1.0~1.5 | 8.0~8.2 | 18.0~18.2 | 0.3~0.5 | ≦5 |
Through process improvement, the microstructure of 304BQ (RK3) is more uniform than that of general 304, with less residual high-temperature ferrite structure, an average grain size of 8.5, low work hardening, uniform surface color, and excellent deep drawing performance
