When choosing stainless steel sheets, it is important to know where they will be used. SS Sheets are designed to withstand corrosive environments. The austenitic stainless sheets have outstanding mechanical properties and are resistant to corrosion due to their high levels of nickel, chromium, and chromium. Many austenitic stainless metals can be formed and weldable. Stainless Steel 304 is the most popular austenitic grade. This blog will help you decide the best grade for your project. It will also compare the differences between 304 stainless steel sheets and 316 stainless steel sheets.
Stainless Steel Grade 304 Sheets
Stainless Steel 304 SheetIt is the most widely used austenitic stainless sheet. It has a high nickel content, which is usually between 8 and 10.5 per cent by weight. There is also a high level of chromium, at around 18 to 20 percent. Manganese, silicon and carbon are other important alloying elements. Iron makes up the majority of the remainder. SS 304 sheets have exceptional toughness even at very low temperatures.
304 stainless steel sheets are resistant to corrosion because of the high levels of nickel and chromium. SS 304 sheets are resistant to oxidation in both intermittent and continuous service at 870 degrees C.
- Refrigerators and dishwashers
- Equipment for commercial food processing
- Heat exchangers
- Containers for chemical substances, even those used for transport
- Equipment for food processing, especially in winemaking, milk processing, and beer brewing.
- Trim, railings and architectural paneling
Stainless Steel Grade 316 Sheets
In terms of high levels of chromium or nickel, grade 316 stainless steel is similar to 304. The primary composition of 316 is iron. It also contains manganese and silicon. The main difference between 304 stainless steel and 316 stainless is their chemical composition. SS 316 typically contains 2 to 3 percent of the molybdenum found in 304, while 304 has only trace amounts. Higher molybdenum levels result inStainless Steel 316 SheetHaving a higher corrosion resistance
Stainless Steel 316 sheet is often the best choice when choosing an austenitic stainless-steel sheet for marine applications. Other uses of 316 stainless sheet include:
- Chemical processing and storage equipment
- Equipment for refinery
- Medical devices
- Marine environments, particularly those that contain chlorides, are very important
- Equipment for food preparation, especially in chloride environments.
- Equipment & laboratory benches
- Coastal architectural panels, railings and trim
Which grade should you choose: Grade 304 or Grade 31?
- If the application demands excellent formability, the higher molybdenum levels in SS Grade 316 sheets can cause problems with formability. SS 304 sheets can be used instead.
- Grade 304 sheets are generally more affordable than Grade 316 sheets, but if there are cost concerns, SS 304 sheets should be used.
- Stainless Steel 316 Sheets are recommended for environments that contain high levels of corrosive elements.
