When it comes to metals, iron is the go-to type since forever because of the quality and price. But one thing that could keep you in doubt whether or not to go for iron is the rust. When it comes to stainless steel, then you need not worry about rusting. But make sure that this must not be the only reason why you should choose steel.

Before choosing the right stainless steel, you must be thinking about having a certain knowledge about 316 stainless steel tube manufacturers and all other properties as well as applications of the same. So let’s get started.

Application, Properties and Uses of Some of the Types and series of Stainless Steel:

300 Series Austenitic – Typical grades are T304 and T316

The Composition of the 300 series Stainless Steel:

The composition of the 300 Series Austenitic – Typical grades T304 and T316 are given in split-ups for you to give a thought.

  • Chromium (17-25%)

  • Nickel (8-25%)

  • Molybdenum (up to 7%) 

 

The composition of these elements under this series might slightly differ with the other types of Stainless Steel under a series. Like, type 316 contains a little more Nickel when compared to the type 304. Also, it contains Molybdenum of 2-3% and thereby making it corrosion resistant.

The Properties of the 300 series Stainless Steel:

The properties of this series of Stainless steel are given below:

  • They uphold a certain strength at high temperatures.

  • These 300 series Stainless steel are corrosion resistant.

  • The Stainless steel of this type is easier to maintain than any other Stainless steel.

The Properties of the 300 series Stainless Steel:

If you are a beginner in choosing Stainless steel and you are not very confident about whether or not you need this much Nickel, and this much Chromium based on your needs and purposes, then here is a list in which this particular series of Stainless steel can be used.

  • Food and beverage cans and other equipment.

  • Surgical application apparatus 

  • Wastewater equipment

  • Architectural applications

  • Chemical equipment and a lot more equipment and application apparatus.

400 Series Martensitic – Typical Grade: 410

The Composition of the 400 series Martensitic stainless steel:

As examined, all types and series of Stainless steel contain a different percentage of different elements. For this series, that is, for 400 Series Martensitic – Typical Grade: 410 the percentage of chromium containment is (12-18%).

The Properties of the 400 series Martensitic Stainless Steel:

The properties of this type and series of stainless steel are given below:

  • They contain a certain percentage of the magnet.

  • The 400 Series Martensitic – Typical Grade: 410 is possible to get hardened while it is exposed to a heat treatment.

  • This type and series of stainless steel are resistant to corrosion.

  • This resistance can be found predominant while getting exposed to the chemical environment as well as mild surroundings.

The Uses of the 400 series Martensitic stainless steel:

The 400 Series Martensitic – Typical Grade: 410 can be used for many kinds of applications. Some of them are given below to give a clear picture to you.

  •  Fasteners

  • Machinery parts

  • Pump shafts and several other appliances.

400 Series Ferritic – Typical grade 430

Composition of the 400 series Ferritic Stainless Steel:

The level of Straight Chromium used in 400 Series Ferritic – Typical grade 430 can be up to 12-18%.

The Properties of the 400 series Ferritic Stainless Steel:

For you to come to a specific decision regarding what type and what series of Stainless Steel, you need to know about the properties of the same.

400 Series Ferritic – Typical grade 430 contain a low amount of carbon.

  • These types of Stainless steel are also empirical to be magnetic.

  • The one thing that is different in this kind and type of Stainless Steel from the other is that they are not heat treatable.

The Uses of the 400 series Ferritic Stainless Steel:

This type of Stainless steel can be found in applications like:

  • Food processing

  • Highly polished trim application and a lot more to note.

Precipitation Hardening – Typical grade: 17-4

Properties of the 400 series Ferritic Stainless Steel:

  • Chromium (12-28%)

  • Nickel (4-7%) martensitic or austenitic

Interestingly, the name, "typical grade 17-4" is derived due to the inclusion of 17% Chromium and 4% Nickel.

 

In conclusion:

Choosing and purchasing the suitable batch of Stainless Steel can be somewhat time-consuming that might eat out our patience. But there are a lot of things you need to know about the entire Stainless steel system before making your purchase. The process might include checking about the Applications, compositions, properties and uses of the Stainless steel that varies from series to series and type to type. We hope you have found out what type and series of Stainless steel you want to satisfy your requirements.
