Rarely Known Facts of Stainless Steel

Stainless Steel and its facts

Stainless steel also known as iron steel and inox is a combination of metals with 10.5 Percentage of chromium content in it. Stainless steel is prominent for its corrosion resistance. It does not easily oxidize, rusts or stains with water as any other steel does. A common use for stainless steel is for cutlery such as knives, forks, and spoons. .

What is chemical composition of stainless steel?

Stainless steel is accessible in a wide range of alloys that includes different elements; however the basic elements are iron, carbon and chromium. Low-carbon steel with no less than 12 percent chromium forms an even layer of oxide on its surface and is stainless. Other elements such as nickel and molybdenum are added to improve corrosion resistance and chromium is the deciding factor.Titanium, for instance, adds significant quality to the finishes items without adding excessive weight.Nickel and niobium are helpful agents to the chromium in resisting corrosion, particularly in low-oxygen conditions.

  • Properties of stainless steel.
  • The amount of oxidation resistance is high when exposed to air.
  • Stainless steel is relatively poor conductor of electricity.
  • Basically stainless steel is ductile in nature.
  • The chromium present in stainless steel form a protective layer and thus stainless steel withstands damage caused by oxidation which is why it is corrosion resistant.
  • When compared with gentle steels, stainless steels have highly stretchable.
  • Different kinds of stainless steel.

Austenitic steels

Austenitic stainless steel contains 16% of chromium and 6% of nickel. By including components, for example: Titanium and Copper, the characteristics of the steel can be changed. These changes can make the steel applicable in high temperature or increase the resistance level. Most steels weaken at low temperatures however the Nickel in austenitic stainless steel which makes it suited to low temperature or cryogenic applications. Austenitic steels are non-magnetic. These types of stainless steels quickly work-solidify. In spite of the fact that they work solidify, they are the most promptly shaped of the stainless steels


Ferritic stainless steels contain just chromium as a chief alloying component. The amount of chromium show ranges from 10.5 percent to 18 percent. They are known for their resistance and weak fabrication characteristics. Fabrication can be enhanced by composite changes. Ferritic stainless steels can't be solidified by warm treatment and are constantly utilized as a part of the tempered condition. They are magnetic in nature. Ferritic stainless steels are typically used in:

  • Vehicle exhausts

  • Fuel lines

  • Cooking utensils

  • Architectural trim

  • Domestic appliances


This type of steel contains high carbon and lower chromium content. These features distinguish martens tic stainless steels from ferritic stainless. Martensitic are magnetic in nature, and are moderately corrosive and poor welding capability. They are typically used for knife blades and surgical instruments. These are not corrosion resistant but are extremely machine-able in nature.

Industrial application of stainless steel.Stainless steel is used for buildings and also for artistic purposes. During deco period stainless steel was in trend. Chrysler is the most famous example. Restaurants use large panels and stainless fixtures and use stainless steel for furnishing and decorating purposes. The feature of being durable makes buildings still retrieve their appearance. It is used in construction of building because of its durability and because it is a wieldable easily and building metal that can be made into artistic pleasing shapes.

Is stainless steel recyclable?

Stainless steel is recyclable. In a normal stainless steel content is made out of around 60% reused material of which roughly 40% starts from end-of-life items and around 60% originates from assembling forms. As per the International Resource Panel's Metal Stocks in Society report, the per capita supply of stainless steel being used in the public area is 80–180 kg in more developed nations and 15 kg in less-developed nations. There is an auxiliary market that reuses usable piece for some stainless steel markets. The item is generally coil and sheet. The material is acquired at a not as much as prime cost and sold to business quality ore manufactures and sheet metal houses.
