Mild steel refers to a kind of steel that is workable. This kind of steel can be drawn, rolled, bent, or forced into any shape or form the user so desires. Alternatively, they are referred to as low-carbon steel and contain a carbon content between .05% and .25%, which is a huge contributing factor to the flexibility of the steel itself. It is also often referred to as cold-rolled steel because it can be reshaped by a process which involves rolling it without heating it. Mild steel can be hardened on the surface by carburising it.
Mild steel is very often used in Petro-Chemical Industries, the Oil and Gas Industry, Pulp and Paper Industries, Mega Projects and Defense Development Industries and the Nuclear Industry. There are various types of end products of this kind of steel such as Mild Steel Flanges, Tube Fittings, Pipe Fittings, Fasteners, Sheets, Bars, Rods, Pipes and more, and they are all used in different industries.
Why Mild Steel is Important in Production
Mild Steel is very much acceptable for use by Diverse Industries because of its strength, flexibility and affordability. The low carbon content of this steel makes it suitable for application in various production contexts such as nuts and bolts, food cans, chains, car body panels, engine parts, wire ropes, rims for bicycles, nails and screws and various outdoor uses.
This steel is mostly important in the production environment because of its flexibility. The low carbon content in the steel makes it attain its flexibility and this in turn makes it a very vital material in construction and metallurgy. The flexibility and reusability of mild steel is one of the many reasons why it fits perfectly for production of other items which are important for everyday use.
Uses of Mild Steel
Mild Steel is used in production, construction, infrastructure, automotive and transportation, mining , oil and gas etc. Depending on the distribution and production companies, you can get durable and affordable mild steel to purchase and use for your various needs.
People use mild steel as an alternative while carrying out construction of infrastructure which requires a large volume of metal stainless steel isn’t exactly cost effective. This is mostly because stainless steel is way more expensive than mild steel and because mild steel is as durable as stainless steel can be in relative amount, it is considered as a reputable replacement.
Also, this kind of steel is used for welding or bending metal. As a result of its flexibility, mild steel is mostly considered for construction which requires welding or bending of metal. In this case, mild steel not only saves money, but also saves time and effort while producing the same quality of final product.
Mild steel is also used to implement construction or manufacturing projects where the steel surface isn’t visible to the eye. What this implies is that the surface of the completed construction would be painted over or coated or covered in any way possible.
Identifying Mild Steel in Everyday Use
The easiest and most relatable way of identifying and describing mild steel or low carbon steel is steel used every day for daily purposes and which is susceptible to rust because it is not stainless steel. Many people refer to the carbon content in mild steel and only very few understand the importance of this compound in the production of steel. The importance of adding carbon to the manufacturing of steel is so that the strength of the steel can be altered. So, in the production of steel, varying amounts of carbon is added to alter the properties of the steel to the suitable texture.
To identify mild steel, look out for a smooth, bright surface (for bright drawn mild steel), while black mild steel is often coated with a blue-grey oxide. Dropping mild steel would produce a ringing note; grinding mild steel would give off a shower of long white or gold sparks and heating mild steel would make it a little tougher but with little change.
Production of Mild Steel
When iron ore is heated up with a specific measure of coke, some gypsum or lime to a eutectic melting point of 1050oC, the resultant mix is referred to as cast iron and is quite brittle to feel. At this point, to make it into steel, there is the need to reduce the phosphorous and Sulphur content. This is done by adding certain ingredients in the mix such as aluminium. This is often completed in a different furnace within the foundry.
