Steel billets international merchandise trade
In simple carbon steels, carbon is the main alloying element, and elements such as manganese, silicon and aluminum are added in small amounts for degassing. The carbon content of these steels plays an important role in increasing their strength after heat treatment. Further information on the international trade in steel billets can be found on our website.
What does billet mean?
Normal carbon steels are the most important group of engineering alloys. These steels are of primary importance for engineering materials because of their relatively low production costs and their wide range of properties. The uses of simple carbon steels are unlimited and can include sheet, strip, rod, wire, pipe products, construction molds, forging, casting, etc. Classification of simple carbon steels Normal carbon steels are divided into different systems depending on their type and application, and there is no single classification that applies to all normal carbon steels.
The two most commonly used systems in this area are ASTM and AISI-SAE AISI-SAE classification system for simple carbon steels This system is used for cold rolled and hot rolled rebar, wire, rod and seamless tube, as well as semi-finished products for forging. Since the carbon content plays an important role in determining their strength in simple carbon steels, this system uses the carbon content to identify different steels. Four numbers are used for the designation, with the first two numbers denoting 10 simple carbon steel. The next two digits indicate one hundredth of a percent carbon. manganese The range of manganese use in unalloyed carbon steels can vary from a maximum of 0.35% in 1005 steel to a maximum of 1% in 1085 AISI steels.
Manganese combines with sulfur in steel to form manganese sulfide. Manganese increases the yield strength of simple carbon steels by breaking up pearlite and creating a solid solution with ferrite. sulfur Sulfur can be present in normal carbon steel up to 0.05%. It usually combines with manganese to form MnS inclusions. When sulfur combines with iron, FeS is formed, which normally precipitates at the grain boundaries. Since FeS is a hard compound with a low melting point, cracks can occur in cold or hot steel. For this reason, and to prevent the formation of this undesirable compound, the ratio of manganese to sulfur in steels should be around 5 to 1.
