304 stainless steel is a commonly used type of austenitic stainless steel that contains between 18-20% chromium and 8-10.5% nickel. It is known for its high corrosion resistance, good formability, and excellent weldability.

304 stainless steel is often used in a variety of industries such as food processing, chemical processing, and pharmaceuticals due to its resistance to corrosion and staining. It is also used in applications where high strength and hardness are not required, such as kitchen utensils, sinks, and appliances.

It is important to note that while 304 stainless steel is resistant to corrosion, it is not completely immune to it. Exposure to certain environments, such as salt water, can still cause corrosion over time. Additionally, 304 stainless steel is not as strong as other types of stainless steel, such as 316 stainless steel, which may be more suitable for applications requiring higher strength and durability.
