18/8 Stainless Steel
Definition - What does 18/8 Stainless Steel mean?
18/8 stainless steel is 304 grade stainless steel, which is the most widely used and flexible austenitic form of stainless steel. The numbers 18/8 represent the composition of this steel as 18% chromium and 8% nickel, making it very resistant to corrosion and oxidation.
18/8 stainless steel is also highly durable and can be fabricated with ease. Cleaning the metal is easy and it is available in various appearances and finishes.
18/8 stainless steel may also be known as austenite steel or 304 grade steel.
Corrosionpedia explains 18/8 Stainless Steel
18/8 stainless steel is an outstanding metal for:
- Auto trim and molding
- Kitchen equipment
- Wheel covers
- Truck bodies
- Exhaust manifolds
- Storage tanks
- Pressure piping and vessels
The percentage of nickel and chromium that is present in this grade of stainless steel provides this metal with good corrosion resistance properties, particularly to moderately caustic and acidic solutions. It also performs in a similar way in most non-severe conditions, except in welding. In cases where stainless steel is to be welded, stainless steel 304L grade is preferred, as it offers more resistance to intergranular corrosion.
