1 and SUS30 1 have high carbon content, high hardness and good ductility. However, SUS304 has low carbon content, low hardness, but strong corrosion resistance.
2.SUS30 1 can obtain very high tensile strength and hardness during cold working, which is widely used as an elastic contact in EMI-resistant products. When molding SUS30 1, attention should be paid to avoiding cracks in corners and side walls. In contrast, SUS304 has good machinability and can be used for deep drawing and other operations.
