Know the variety of steels available in the market
There are a very large number of shapes and types of steel products. The wide variety of steel available in the market is due to the fact that each of its applications requires changes in composition and shape.
Regarding the chemical composition of steel, processing, controls and testing (in order to meet customer specifications), as well as its end use, the steel ratings are:
Carbon Steel:
They are low carbon or low alloy steels of broadly defined chemical composition.
Steels Alloy/Special
They are alloyed or high carbon steels of narrowly defined chemical composition for all elements and rigid specifications.
Mechanical construction steels:
They are carbon and low alloy steels for forging, bearings, springs, shafts, machined parts, etc.
Tool steels:
These are high carbon or high alloy steels for the manufacture of tools and dies for hot and cold work, including fast steels.
Another form of classification added to steel is its geometric shape. The categories are:
Semi-finished:
Products coming from continuous casting process or roughing rolling destined for subsequent processing lamination or hot forging.
Flat Products:
Steel products, the result of a rolling process whose width is extremely greater than the thickness (L> E), and are sold in the form of plates and coils of carbon and special steels.
Uncoated, in "carbon steels":
Coils and thick plates of hot strip mill – LTQ (5mm < E > 12,7mm)
Coated in "carbon steel":
In "special steels":
Long Products:
Steel products, resulting from the rolling process, whose cross sections have polygonal shape and their length is extremely larger than the largest dimension of the section, being offered in carbon and special steels.
In carbon steels:
