Stainless steel plate is a common metal material, its main components are iron, chromium, nickel and other elements. According to different chemical composition and organizational structure, stainless steel plates can be divided into various steel grades, some of which are common steel grades include:

1. Austenitic stainless steel (AISI 304): This is the most common type of stainless steel and contains 18% chromium and 8% nickel. It has excellent corrosion resistance and is widely used in food and beverage processing, medical equipment, and automotive applications.

2. Martensitic stainless steel (AISI 410): This type of stainless steel contains 17% chromium and 1% carbon. It has high strength and hardness and is commonly used in structural components such as beams and plates.

3. Duplex stainless steel (AISI 2205): This type of stainless steel contains between 20% and 25% chromium and 2% to 3.5% nickel. It has excellent corrosion resistance and high temperature strength, making it suitable for use in high-temperature applications such as heat exchangers and boilers.

4. Superalloy stainless steel (SUS904L): This type of stainless steel contains between 18% and 20% chromium and 2% to 3% nickel. It has extremely high corrosion resistance and is used in applications where high temperatures and pressures are present, such as nuclear power plants.

Here is a table summarizing some of the key properties of these different types of stainless steel:

Type	Chromium Content (%)	Nickel Content (%)	Strength (MPa)	Tensile Strength (MPa)	Elongation at Break (%)
Austenitic	18	8	720-800	550-650	20-25
Martensitic	17	<1	>720	>550	>20
Duplex	20-25	<1	>720	>550	>20
Superalloy	>25	<1	>720	>550	>20

Note that the properties of stainless steel can vary depending on the specific grade or type of steel used.
