SUS304 stainless steel, also known as 304 stainless steel, is one of the most widely used and versatile types of stainless steel. Its unbeatable strength, corrosion resistance, and durability make it an ideal material for various industries, including construction, automotive, and medical equipment. In this article, we will explore the applications of SUS304 stainless steel and its properties that make it a popular choice among manufacturers and engineers.
The widespread adoption of SUS304 stainless steel can be attributed to its unique combination of properties, including high corrosion resistance, excellent formability, and good weldability. Its corrosion resistance is due to the presence of chromium, which forms a thin layer of oxide on the surface, protecting the underlying metal from corrosion. This property makes it suitable for applications where the material is exposed to harsh environments, such as marine or chemical processing industries.
Properties of SUS304 Stainless Steel
SUS304 stainless steel has a chemical composition of 18% chromium, 8% nickel, and 0.08% carbon. This composition gives it excellent corrosion resistance, ductility, and weldability. Its physical properties include a density of 8.0 g/cm³, a melting point of 1450-1475°C, and a thermal conductivity of 15 W/m-K.
Corrosion Resistance
One of the most significant advantages of SUS304 stainless steel is its corrosion resistance. It has a high resistance to corrosion in acidic and alkaline environments, making it suitable for applications where the material is exposed to chemicals or cleaning agents. Its corrosion resistance is also due to its ability to form a passive film on its surface, which protects it from further corrosion.
| Corrosion Resistance | Value |
|---|---|
| Corrosion Rate (mm/year) | 0.1-0.5 |
| Pitting Resistance Equivalent Number (PREN) | 19.5 |
