Steel is an alloy of Iron and Carbon and other elements and Iron is the base metal of steel. Steel can withstand corrosion due to the application of chromium oxide. We mainly use steel in constructions in the form of TMT bars, most commonly SAIL TMT Bars.
Steel can be categorized into four groups:
1) Carbon Steels
Carbon steel are made from a combination of iron and carbon. We can make steel of different qualities by varying the percentage of carbon. In general, the higher the amount of carbon the stronger and brittle the steel will be. The low carbon steel is called Wrought Iron and will be used in decorative articles. Medium carbon steel is very strong in nature and is mainly used for constructing large structures like bridges. High carbon steel is used in wires etc.
2) Alloy Steels:
Alloy steels are made up of a small percentage of one or more metals besides Iron. The addition of alloys changes the properties of Iron and various varieties of steel are created. We can distinguish different qualities of steel based on their property.
3) Stainless Steel
Stainless steel at least contains 10% – 20% of Chromium which makes the steel extremely resistant to corrosion (rust). The stainless steels are of three types;
Austenitic Steel: These steels have a high amount of chromium and also contain a smaller amount of carbon and nickel. These are non-magnetic and are very commonly used for food processing and piping.
Ferritic Steel: These steels contain about 15% chromium and fewer amounts of carbon and other metal alloys. These steels can be strengthened further by cold working. These steels are magnetic, strong, and hard in nature.
Martensitic steel: This steel contains a moderate amount of chromium, nickel, and carbon. These are magnetic and heat-treatable. These steels are used to make cutting tools like a knife, surgical equipment, etc.
4) Tool steel
These steels are made up of tungsten, molybdenum, cobalt, and vanadium. These are heat resistant materials and durable in nature. These are used to make hardware tools like drillers etc. Steel dealers will usually have a stock of different grades of steel.
