What is 18-8 Stainless Steel?
18-8 stainless steel is a term often used to describe a specific composition of stainless steel, which is essentially 304 stainless steel. The name “18-8” refers to the composition of the steel: 18% chromium and 8% nickel. This grade is known for its excellent corrosion resistance and good mechanical properties.
Key Characteristics of 18-8 Stainless Steel
- Corrosion Resistance: Excellent resistance to oxidation and corrosion, making it suitable for a variety of environments.
- Strength and Durability: Offers good tensile strength and durability, suitable for various applications.
- Aesthetic Appeal: Polished surfaces and a clean appearance make it an attractive choice for consumer products.
What is 304 Stainless Steel?
304 stainless steel is one of the most commonly used stainless steel alloys, known for its versatility and wide range of applications. It is often referred to as “18-8 stainless steel” because its composition includes 18% chromium and 8% nickel, aligning with the general characteristics of 18-8 stainless steel.
Key Characteristics of 304 Stainless Steel
- Corrosion Resistance: Exceptional resistance to corrosion and oxidation, making it ideal for use in harsh environments.
- Formability: Easily formed and welded, which is beneficial for manufacturing processes.
- Temperature Tolerance: Can withstand temperatures up to around 870°C (1600°F), suitable for high-temperature applications.
Comparison Between 18-8 Stainless Steel and 304
While 18-8 stainless steel and 304 stainless steel are essentially the same, understanding their specific applications and properties can help in selecting the appropriate material.
Composition
- 18-8 Stainless Steel: Contains approximately 18% chromium and 8% nickel.
- 304 Stainless Steel: Also contains around 18% chromium and 8% nickel. The exact composition of 304 stainless steel aligns closely with the 18-8 specification.
