Differences between Mild Steel and High Strength Steel

Mild steel and High strength steel are two types of carbon steels that are present. There is 0.90% carbon by weight in Carbon steel, and the same type of low carbon amount by weight is present in Mild steel. High strength steel also has carbon in small amount, although it contains some amazing alloying components having superior tensile strength. There are some basic differences between mild steel and high strength steel.

Properties

Mild steel is not fragile, It is one of its major properties. It has solid quality and does not actually go through a process of tempering. It is also a superior conductor of electricity. Thus, it can be used in welding. It also boasts of higher malleability due to the presence of low amount of carbon. Mild steel can easily be magnetized due to its ferromagnetic properties. This kind of material is also appropriate for various structural purposes. This kind of material has more amount of carbon than low carbon steel.
In comparison, high tensile steel boasts of superior tensile and yield strength. There are distinctive alloying components, which can help ensure that the steel has tensile strength. Such types of components are vanadium, molybdenum, nickel, manganese, silicon and chromium – all of which can be used for special types of purposes – such as for manufacturing parts in crane ropes, automobiles etc.

Composition

Carbon Steel happens to be unalloyed steel, and has various components such as Silicon, Phosphorus, Manganese, Sulphur and Carbon. A type of carbon steel, Mild steel has 0.15 – 0.25% carbon. In High tensile steel, the carbon content includes:

• Phosphorus- 0.05%
• Silicon – 0.20%
• Manganese – 0.60%
• Sulphur – 0.05%
• High tensile steel – 0.60 – 0.80%

Strength

The strength of steel lies in the ability to oppose stress, weight or force. Mild Steel has lower level of strength as compared to that of High tensile steel.

Uses

Mild steel is used in sheet piles, roof coverings, reinforcing bars, moved areas and more. In pre-stressed solid development constructions, Post tensioning or Pre tensioning involves the use of High Tensile Steel. This is used for nuclear power stations, pulling Hydropower stations, hoisting, atomic reactors and different types of lifting.

Flexibility

The flexibility of a material is marked by its ability to get pressed or hammered into shape with no splitting or breaking. Mild steel is more malleable as compared to high tensile steel.
There is a higher level of carbon in High ductile netting, as compared to standard mild steel. It is subjected to a lot of heat, followed by quenching, at the time of its generation. In other words, it is cooled right after being heated up. A lot of additional strength is needed for this process. Generally, the yield strength of High tensile netting is between 50,000 to 100,000 pounds in each square inch. All the additional strength is beneficial in offering a fantastic, reliable fence.
