Applications
- CNS 304 Stainless Steel is an austenite steel and contains between 16% and 24% chromium and up to 35% nickel. The most common type of 304 stainless steel is the 18/8 or 18-8 steel, which constitutes 18% chromium and 8% nickel. 304 stainless steel is the most popular and widely used grade of steel
CNS 304 Stainless Steel is all around us. It’s used in a variety of products across many different sectors. Here are just a few examples of some common uses:
Chemical industry – Large storage tanks and containers for liquids and solids
Food industry – food processing equipment like milking machines, storage tanks, hauling tanks, piping, valves, milk trucks etc. Also used in breweries, wine-making and the fruit juice industry.
Domestic uses – 304 stainless steel can resist the corrosive action of acids found in fruits, milk, meat and vegetables, and is fairly resistant to abrasion. Therefore, it is widely used in sinks, tabletops, stoves, refrigerators, cutlery, utensils and various other appliances.
Architectural uses – paneling, molding, railings, décor.
Industrial applications – tools, bolts, nuts, screws etc.
Automotive and aerospace industries – fuel tanks, various structural components.
Hospitals – surgical equipment.
Commercial – sanitary fittings, pipes
