Different Types of Stainless Steel and When To Use Them

2023-08-10
These days, you see stainless steel everywhere you go. Whether it’s your cabinets, fridge, countertops, or even your car, stainless steel has various applications. 
However, what many people don’t know is that stainless steel falls under a variety of categories and grades that indicate its strength and other factors, such as oxidation resistance, melting point, and corrosion resistance. If this is all new to you, don’t worry—check out this explanation of the different types of stainless steel and when to use them.



Austenitic Stainless Steels
Companies and manufacturers use austenitic stainless steel most frequently since this material has a high chromium content. 
This means that the stainless steel will resist corrosion and rusting better than other metals, and it is non-magnetic. 
That said, you can make austenitic stainless steel magnetic after you perform cold work on the steel. 
People use this form of stainless steel for large-scale industrial applications, such as building airplane structural components. 
Still, there’s a chance you’ve purchased something as simple as cutlery that contains this type of steel without even knowing it.

Ferritic Stainless Steels
Ferritic stainless steel is a magnetic material boasting great corrosion resistance properties, and manufacturers often harden this type of steel through cold working. 
You might be surprised to learn that this steel is relatively inexpensive due to its low nickel content. 
Also, it is another metal manufacturers use for cookware, although this steel can be used to create car components as well. 
Ferritic stainless steel is both malleable and strong, making it one of the most versatile and popular choices when considering the different types of stainless steel and their applications.

Duplex Stainless Steels
This form of stainless steel is a hybrid of both austenitic and ferritic stainless steel. 
This material is stronger than its individual counterparts, with improved cracking resistance and better erosion-resistant capabilities. 
Duplex stainless steel is magnetic due to its high ferritic content, and it’s easy to weld. 
This steel is perfect for industries that drill for oil underwater since it is resistant to corrosion from saltwater.
