When selecting stainless steel sheets one must make sure in which environment the sheets need to be used these SS Sheets that endure corrosive environments are typically used. Possessing exceptional mechanical properties, the high amounts of nickel and chromium in austenitic stainless steels also provide good corrosion resistance. Stainless Steel 304 & 316 are two of the most commonly used grades of austenitic. To help you choose the right grade for your project, this blog will compare the difference between 304 and 316 stainless steel sheets.
Stainless Steel Grade 304 Sheets
- 304 stainless steel sheet is generally considered to be the most common austenitic SS plate. It contains a high nickel content which is usually between 8 and 10. 5% by weight and a high amount of chromium at about 18-20% by weight. Another very important alloying element includes manganese, silicon and carbon. Sheets of Stainless Steel 304 Sheet have excellent toughness even down to cryogenic temperatures called very low temperatures.
- High amounts of chromium and nickel give 304 stainless steel sheet excellent corrosion resistance. Stainless Steel 304 sheets have good resistance to oxidation in intermittent service up to 870 degrees C and in continuous service up to 925 degrees C. Common applications of 304 stainless steel sheets include
- Appliances such as refrigerators and dishwashers
- Commercial food processing equipment
- Heat exchangers
- Chemical containers, including for transport
- Food processing equipment, particularly in beer brewing, milk processing & winemaking
- Architectural paneling, railings & trim
Which Grade should you use: Grade 304 or Grade 316
- If the application requires excellent formability the higher molybdenum content in Stainless Steel Grade 316 Sheets can have adverse effects on formability and hence SS 304 Sheets can be used
- Grade 304 sheets are typically more affordable than Grade 316 sheets if the application has cost concerns SS 304 Sheets should be used.
- The environment includes a high amount of corrosive elements, or the material will be placed underwater or be exposed to water consistently, or in applications where greater strength and hardness are required Stainless Steel 316 Sheets should be used.
