What is Stainless Steel

Video Source

Stainless steel products are used all over the world in a variety of fields. It’s a corrosion-resistant metal that is durable and moldable. This article will discuss the four types of stainless steel: Austenitic, Ferritic, Martensitic, Duplex, and Precipitation Hardening.

Austenitic

Austenitic makes up the largest portion of stainless steel available. It is used in medical and food utensils, and more. They’re weldable and non-magnetic.

Ferritic

Ferritic contains nickle and other alloying elements. They have good ductility and formality, but aren’t great at high temperatures.

Martensitic

Martensitic has higher carbon content which affects forming and welding. This metal is magnetic and heat treatable. It’s often used in surgical equipment, knives, and other cutting tools.

Duplex

Duplex has higher yield strength and greater stress corrosion cracking to chloride. Duplex steel is often used in chemical plants and piping.

Precipitation Hardening

Precipitation hardening steels contain alloys that allow them to be hardened by a solution and heat treatment. They then age into Austenitic or Martensitic steel.

The various types of stainless steel don’t encompass every type of steel that exists. The industrial applications are endless. If you are interested in learning more about steel then click on the link to the video above.
