Hot roll our large hot roll steel stock is available in various shapes and alloys with full sizes available.
The mills that produce hot rolled are very efficient consistently flattening the product into large rolls which leads to lower costs for o neal steel customers.
The starting material is usually large pieces of metal like semi finished casting products such as slabs blooms and billets.
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material.
It s through a series of breakdown semi finishing sizing semi roughing roughing and finishing that cold rolled steel shapes can be created.
Hot rolled steel sheet and plate provides a rougher surface than cold rolled steel and plate.
After the grains deform during processing they recrystallize which maintains an equiaxed microstructure and prevents the metal from work hardening.
The finished products need less additional surface finishing to achieve a good result as the surfaces are already smooth.

Hot rolled steel is created by rolling steel at a high temperature that lends it to being easily shaped and formed.
The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications.
Cold rolled steel is stored and sold in coiled form after rolling.
Steel comes in many grades specifications shapes and finishes the world steel association lists over 3 500 different grades of steel each with unique properties.
Although cold rolled steel is more expensive than hot rolled steel the aforementioned advantages make it useful for many applications.
