What is Stainless Steel?

Stainless steel is a popular metal that has a wide range of applications in a variety of industries.

It possesses a number of characteristics that make it excellent for this post use. It is anti-rust and anti-stain, for example. Due to the inadvertent addition of Chromium to Iron, stainless steel was created. It has other advantages when compared to other metals and alloys such as Iron and Steel.

You'll learn about the properties of the three, as well as their relationships and differences, in this section.

Why, if the stainless steel is made of steel and very certainly iron, does it not discolor when it rusts? Anything with iron parts is bound to rust if not properly cared for.Stainless steel, on the other hand, lives true to its name. So, what distinguishes stainless steel from other metals? This is due to the fact that it is made up of different elements.

Because iron, the metal used to manufacture steel, occurs naturally in combination with other elements, it corrodes.When iron ore is purified artificially to manufacture steel, it becomes unstable and easily recombines with oxygen.

Properties of Stainless Steel


Iron is a chrome-colored durable and ductile metal.

It is classed as a ferromagnetic metal and has an atomic number of 26. Some metals have a property called ferromagnetism, which allows them to function as magnets and attract other metals. This is why most people make their items out of stainless steel. Stainless steel items survive longer due to their anti-corrosion properties.

Iron is mostly sourced from the hematite ore. We have different iron types depending on the extraction and purification process. Pig iron is the most impure kind of iron available. Other types of iron, such as cast iron and wrought iron, are made from pig iron. The percentage of carbon present determines the differences between the three.Wrought iron is the purest of the three types.

Stainless Steel

Stainless steel, contrary to popular belief, is not a single thing. Rather, it is a single broad organization that incorporates a wide range of activities.

It is a chromium-based alloy with at least 11% chromium content. It does not rust and is heat resistant due to its composition. Other elements such as carbon (0.03-1.00 percent), nitrogen, silicon, sulfur, niobium, and molybdenum can be present depending on the stainless steel type.

These Pipes have high tensile strength. As a result, they can bear extremely heavy loads. You can get SS with higher tensile strength, which means it can sustain more weight, depending on the stainless steel variety.


Cast iron is also used to make steel.

They, unlike the three forms of iron outlined previously, are an alloy (a mixture of different elements). It is made from the combination of iron and carbon, which is a natural element. Steel has 2.14 percent carbon, which accounts for its superior strength and durability over iron. SS, depending on the type, can withstand extreme temperatures.

While it will eventually melt, it can withstand a certain amount of heat before doing so.

Differences between Iron, Steel, and Stainless Steel

The composition, physical properties, and functions of the three metal kinds vary significantly.

The others are alloys, while the iron is an element. Steel and stainless steel have several physical features that are not found in iron due to the fact that they are alloys. They, for example, are stronger than iron due to their carbon content. Because of the presence of Chromium, It has better heat resistance and anti-rust qualities than the other two.

Applications of Stainless Steel


One of the most common uses for stainless steel is in this application. Almost every household has at least one set of stainless steel silverware or cookware.Because SS does not discolor easily, it is utilized to make numerous kitchen goods. As a result, it meets expectations in terms of both looks and performance.

Medical Equipment

Stainless steel is utilized to make medical tools because of its anti-rust and anti-stain qualities.It's antibacterial and doesn't react with a lot of cleaning solutions, so it's simple to clean and sterilize. It's used to make hemostats, surgical implants, and temporary crowns, among other things.

Food and Catering

Stainless steel is utilized in food and catering products because it does not alter the qualities of the food.It's also great since it's anti-corrosive and easy to clean, keeping microbes at bay.


Because of its anti-rust and other qualities, SS is becoming more common in automobiles. Because of its anti-rust properties, it is utilized in the manufacture of automobiles and trains, for example.It is a significant aspect of aircraft manufacture when combined with its lightweight feature.
