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 is the difference between 316 stainless and 18-8?

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 grade is a 18-8 stainless steel bolt?

a ) 18-8 Stainless Steel: (18% Chrome, 8% Nickel, . 08% Maximum Carbon) – 18-8 Stainless refers to 300 series stainless steel. 303 and 304 Stainless are the most commonly listed grades, the standard grade for stainless fasteners. They are corrosion-resistant and durable.

Are 18 8 and 304 stainless steel the same?

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. Therefore, the higher the nickel content, the more resistant the stainless steel is to corrosion.

How strong is 304 stainless steel?

Stainless Steel 304

Properties Value
Mechanical properties
Hardness, Rockwell B 82

Are 304 and 18 8 the same?

18/8 and 18/10: These are the two most common grades of stainless steel used for food preparation and dining, also known as Type 304 (304 Grade) and are part of the 300 series. For example, 18/8 stainless steel is comprised of 18% chromium and 8% nickel.

Is 304 stainless steel the best?

As the most widely used of all stainless steel, 304 stainless steel is most notably present in industrial applications and kitchen equipment. It is a highly heat-resistant grade, and offers good corrosion resistance to many chemical corrodents, as well as industrial atmospheres.

What is the difference between 304 and 409 stainless steel?

1 Answer. 409 Stainless is specifically made for high temperature situations, has better heat transfer and warps less then 304 Stainless Steel while 304 Stainless Steel tends to corrode slower but has poorer heat transfer.

What does 304 mean in stainless steel?

304 grade stainless steel is known to be the most widely used and flexible austenitic form of stainless steel. It contains 8% nickel and 18% chromium , making it ultra resistant to corrosion and oxidation.

What are the properties of 304 stainless steel?

Properties. The 304 stainless steel is classified as a T 300 series austenitic stainless steel alloy, containing a minimum of 8 percent nickel and 18 percent chromium with a maximum of 0.08 percent carbon. This grade of steel also has excellent drawing properties and can be formed into bar, rod or sheet stock.

What is density of 304 grade stainless steel?

Type 304 steel is part of the 3xx stainless steels or those alloys which are blended with chromium and nickel. Below is a chemical breakdown of 304 steel: The density of 304 steel is around 8 g/cm 3, or 0.289 lb/in 3.
