SUS430 stainless steel plate is a type of ferritic stainless steel sheet, and its plasticity and strength are important mechanical performance indicators. The following is a comparison analysis of the plasticity and strength of SUS430 stainless steel plate:

Plasticity: The plasticity of SUS430 stainless steel plate is a bit poor due to its ferritic structure and low carbon content, which results in limited ductility and elongation. Additionally, it is prone to defects such as cracking during the processing.

Strength: The strength of SUS430 stainless steel plate is relatively low, with a yield strength generally below 200 MPa and tensile strength below 450 MPa. This is mainly due to the lower content of carbon, chromium, nickel, and other elements in SUS430 stainless steel plate, leading to a lower strength. However, the strength of SUS430 stainless steel plate can be enhanced by heat treatment, such as solution treatment and aging treatment, which can improve its strength and hardness.

In conclusion, SUS430 stainless steel plate has relatively low plasticity and strength. However, it possesses advantages of good corrosion resistance and relatively lower cost, which make it still widely used in specific field.
