Properties of Stainless Steel

We all are living in the modern era where you see and experience new technologies and advanced infrastructures. To build these types of technologies and infrastructure various materials and their alloys are used. In that most common and widely used material, an alloy is Stainless Steel. Did you hear this name in your day to day life? right? Stainless Steel plays an important role in our day to day life as it possesses several quality properties. Before going further first take a look at how stainless steel material forms.

Metal Alloy Stainless Steel is made up of a mixture of various metal elements like chromium, nickel, molybdenum, silicon, aluminum, and carbon. When iron mixed with carbon produces Stainless Steel as the main steel component. The compositions of chromium, nickel, molybdenum, silicon, aluminum, and carbon are varies depending on the type of stainless steel grade.


Properties of Stainless Steel 

Stainless Steel products are highly demanded in various industries because of their high rated stainless steel properties. The Stainless Steel properties are more advantageous than plain carbon mild steel. In spite of having a wide range of properties, in general, when compared with mild steel, stainless steel has:

  • Excellent Corrosion Resistance
  • Higher Cryogenic Toughness
  • High Work Hardening Rate
  • Good Hot Strength
  • Higher Ductility
  • Excellent Strength and Hardness
  • Lower Maintenance
  • A more attractive appearance.


Stainless Steel is firstly used for making kitchen utensils due to it does not affect the flavor of food and easy to clean. Apart from this, many products are manufactured from stainless steel include surgical instruments, plates, sheets, bars, wire, kitchen cutlery, building construction materials, hardware, and cookware.

Chromium present in stainless steel offers resistant to rust and the addition of nickel provide corrosion resistance properties in aggressive cases. More addition of molybdenum gives localized resistance to corrosion against scarring. Depending on the various compositions there more than 150 stainless steel grades, but only 15 are regularly used.

Stainless Steel is also known as hard and strong substance; it is not a good conductor of electricity and heat. Though provides high ductility and good magnetic properties. Steel is mainly classified as five major types like Austenitic, Ferrite, Martensitic, Precipitation, Hardening, and Duplex.

Austenitic Stainless Steel contains 16-26% chromium and less than 35% nickel with the addition of manganese and nitrogen. Due to the addition of manganese & nitrogen, austenitic stainless steel is ductile and tough with cryogenic and high-temperature strength properties.

Ferrite Stainless Steel has 30% chromium and less than 15% nickel that is crystal in nature. This steel is well known for its ferromagnetic properties and malleability & ductility. There is a lack of elevated temperature mechanical properties.

Martensitic Stainless Steel is a made up of a mixture of 18% chromium and carbon. This steel can be hardened by heat treatments. The martensitic stainless steel is well demanded in the market due to ferromagnetic properties and outstanding corrosion resistance.
