What is the difference between 304 and 18-8?

What is the difference between 304 and 18-8?

are the composition of the stainless steel and refer to the amount of chromium and nickel (respectively) in the product. For example, 18/8 stainless steel is comprised of 18% chromium and 8% nickel. 304 grade stainless steel is also comprised of no more than 0.8% carbon and at least 50% iron.

Which stainless steel screws are strongest?

BUMAX® Ultra has proven itself as the world’s strongest bolt – in various highly-demanding critical fastener applications around the world where standard fasteners are simply inadequate.

What does 18-8 mean for a screw?

18-8 Grade Stainless Steel This refers to the 300 series of stainless steel with a chromium and nickel content in percentages. That means that an 18-8 grade fastener has 18% chromium and 8% nickel content. 18-8 type stainless steel has better resistance to corrosion than the 400 series.

Are 18-8 and 316 the same?

The 316 stainless steels have 2-3% molybdenum added while the 18-8 series stainless steels do not. While it has comparable strength characteristics, 316 and 316L stainless steel have a higher degree of corrosion resistance due to the addition of the element molybdenum.

What is the difference between 18-8 and 303 stainless steel?

18-8 is a non-magnetic type of stainless steel. 303 stainless steel is similar to 18-8 stainless, but has a larger sulfur content, making it one of the more machinable stainless steel grades. This machinability has made it very popular in the fastener industry, particularly in the manufacture of spacers and standoffs.

What’s the difference between 316 and 18 series stainless steel?

The 316 stainless steels have 2-3% molybdenum added while the 18-8 seriesstainless steels do not. While it has comparable strength characteristics, 316 and 316L stainless steel have a higher degree of corrosion resistance due to the addition of the element molybdenum.

What’s the difference between 304 and 18-8 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.

What is the code for 18 8 stainless steel?

Sometimes, Its code is 301 in JIS. So 18-8 stainless steel is also known as 304 grade stainless steel. This grade of stainless steel is generally regarded as one of the populate in stainless steel. Because it is widely available and the 18-8 stainless steel price is cheap.

What are the pros and cons of 18-8 stainless steel?

Pros and Cons of 18-8 Grade Stainless Steel As already mentioned, 18-8 grade stainless steel is celebrated for its superior corrosion resistance. However, it is known to show signs of corrosion when exposed to chlorides, such as salt. Therefore, it is not the ideal stainless steel to use for marine applications.
