Check Pros And Cons Of 304 And 316 Stainless Steel
SS 304/18-8 stainless steel/A2 Stainless
18-8 stainless steel is also referred to as 304 stainless steel because the chemical composition is the same in both 18-8 & 304 SS. The no 18-8 represent the chemical composition, i.e. chromium 18% and nickel 8%, which make it excellent resistance to corrosion. In 304 there two more grade, i.e. 304L, which is low carbon grade and 304H, which is high carbon grade and 304 is general grade. SS 304 also known as A2 stainless.
Let us talk about the pros and cons of AISI 304 or 18-8 stainless steel
Pros
- High corrosion resistance
- Less heat sensitive than 302
- Stronger than mild steels
Cons
- Vulnerable to saltwater corrosion
- Requires proper tools to machine well
04/18-8 SS should be used when the low cost is more important than corrosion resistance and not working in a marine environment and product is not exposed in a corrosive environment.
Application of 304(18-8 Stainless steel)
- Appliances such as refrigerators & dishwashers
- Commercial food processing equipment
- Heat exchangers
- Structures in atmospheres that would corrode standard carbon steel
SS 316/18-10 stainless steel/A4 Stainless
SS 316 contains 16% chromium and 10% nickel and other elements; therefore, it is also referred to as 18-10 stainless steel. SS 316 have other grades like 316L, which is a low carbon grade, 316F free machining grade and 316N, which is high nitrogen grade. It is suitable for marine and high salinity environment. It is also called A4 stainless.
Let us talk about the pros and cons of AISI 316 or 18-10 stainless steel.
Pros
- Stronger than 304 stainless
- Extremely corrosion resistant
- performs well against pitting
- Resistant to salt water
- Resistant to caustic chemicals
Cons
- Requires the precise tools to machine well
- More expensive than 304
SS 316 is used when corrosion resistance is more significant than cost and if we are working in a marine environment and with corrosive chemicals.
Application of 316(18-10 Stainless steel)
- Chemical processing and storage equipment
- Refinery equipment
- Medical devices
- Marine environments
Summary
So depending upon working environment and the product budget best grade should be selected to create a project so that it can last for a longer time in a working environment because in some cases SS 304 work better and in some cases, SS 316 work better
