The chemical composition of SUS301 stainless steel plate (Coil) mainly includes iron (Fe), chromium (Cr), nickel (Ni), manganese (Mn) and nitrogen (N) and other elements. Among them, the content of chromium is high, about 16% to 18%, and the content of nickel is relatively low, about 3% to 5%. In addition, the stainless steel also contains a certain amount of silicon, phosphorus, sulfur and other elements.

2.Mechanical Properties

SUS301 stainless steel plate (Coil) has good mechanical properties, its tensile strength, yield strength and elongation and other indicators are high. At room temperature, the tensile strength can reach more than 520MPa, the yield strength can reach about 210MPa, and the elongation can reach more than 40%. In addition, the stainless steel also has good plasticity and toughness, and is not easy to appear brittle fracture.

3.Heat Treatment State

SUS301 stainless steel plate (Coil) usually adopts two heat treatment states of solution treatment and aging treatment. Solution treatment is to heat the stainless steel to a high temperature single-phase zone, so that the chromium element is further dissolved into austenite, and then quickly cooled, so that the austenite into martensitic structure. Aging treatment is to heat the stainless steel plate (Coil) after solution treatment to a lower temperature, so that precipitation hardening occurs inside the metal.

4. Low Temperature Impact Test

In low temperature environment, the impact toughness of SUS301 stainless steel plate (Coil) will be affected. In order to evaluate its performance at low temperatures, low temperature shock tests are usually required. According to the test results, the impact resistance and applicable temperature range of the stainless steel at low temperature can be determined. In general, the impact toughness of SUS301 stainless steel plate (Coil) at low temperatures will be reduced, but it can still maintain good mechanical properties in the temperature range above -20 ° C.

5. Main Application Scenarios

Because SUS301 stainless steel plate (Coil) has good mechanical properties and corrosion resistance, it is widely used in various fields. For example, it can be used to manufacture parts and structural parts that need to withstand greater stress, such as aircraft parts, automotive parts, petrochemical equipment, etc. In addition, due to its beautiful surface quality, it can also be used to manufacture decorative pieces and products that require high surface quality.
