It is usually used in applications where the finish isn’t vital to the project because of its dull surface finish. Many kinds of hot-rolled steel sheets are supplied by the leading Steel Dealers and Steel Suppliers in Chennai.
Although most people would characterize this dull, boring type of steel with the word “lacklustre,” it is actually one of the more interesting in appearance (besides galvanized which we will get to later). Dry hot-rolled sheets and coils are a darker grey than most other steel forms, with a silvery blue, almost purple stripe running down both sides. The stripe’s color gives the feeling that the steel’s surface is still hot to the touch. This, though, is due to the hot rolling phase and residual mill size. These types of steel are generally supplied by MS steel suppliers in Chennai.
Automotive and Truck Frames dump truck made of hot-rolled steel
So, maybe you’re not a big fan of art. Truck and car seat frames are also made of hot-rolled steel. To help prevent rusting and allow for painting, the metal is normally pickled and oiled (P&O) before being used in this application.
Sculptures in the Arts
Hot rolled dry steel is one of the most widely used steel forms for art sculptures due to its distinctive finish (besides stainless steel). The colour variations in the steel sheets give the sculpture a unique personality. The disadvantage of hot roll drying is that it is susceptible to rusting because it lacks a finish. However, you may find a sculpture with a rusted finish in a hotel lobby, airport, or office building. The sculpture was most likely made of hot rolled steel that had been left to rust before being coated with a protective finish (or it could have just been sandblasted to look like rust, either way, it is likely still hot-rolled)
Pickling and Oiling Process with Hot-Rolled Pickles
The P&O process cleans the mill scale by removing the black oxide scale. After the P&O process, the MS chequered plate is given a better surface finish, and it is now known as hot rolled P&O. P&O that has been hot rolled has a cleaner, more even finish. It is slightly less dark in colour and no longer has prominent, bright strips along the edges.
Agriculture Machinery
So you’re not interested in art or automobiles? Then maybe you’re a farmer. Because of its high strength and formability, hot-rolled steel is commonly used in agricultural machinery. Depending on the steel grade, the formability of hot-rolled P&O can vary from simple bends to complex draws. Harvesters, tractors, and other farm equipment all benefit from the power that hot-rolled steel provides. Know that the next time you go grain harvesting, you’re probably riding on a huge green hot rolled rig.
