S30400

S30400 refers to a specific grade of stainless steel, commonly known as Type 304 or 18-8 stainless steel. It is an austenitic stainless steel that offers a good balance of corrosion resistance, formability, and weldability. The "S" in S30400 designates stainless steel, and the following numbers indicate its composition and grade.

The primary alloying elements in S30400 are chromium and nickel. It typically contains a minimum of 18% chromium and 8% nickel, hence the common name 18-8. This composition provides excellent resistance to a wide range of corrosive environments, particularly atmospheric conditions and many organic and inorganic chemicals. It is not prone to rusting or staining in normal use.

S30400 is widely used across various industries due to its versatility. Common applications include kitchen sinks and cookware, food processing equipment, chemical tanks, architectural trim, and fasteners. Its non-reactive nature makes it ideal for food and beverage applications as it does not impart any metallic taste or odor. The steel can be easily fabricated through processes like drawing, bending, and welding, making it suitable for complex shapes and designs. While it offers good strength, it is not intended for applications requiring extremely high tensile strength or hardness at elevated temperatures.
