Billets and blooms are semi-finished casting products produced in a steel mill that need further processing to end up as a finished good. Billet and Blooms generally differ in their sizes. Billets come in square cross section, whereas Blooms come in both square and rectangular cross sections. Billets have a square cross-section area of less than 36 sq. inches. Blooms cross-section must be greater than 36 sq. inches.
About our in-stock
AS Steel generally in-stocks MS Blooms and MS Billets with a standard length of 12m (Can be customized as per customer requirement). Made by RINL (Rashtriya Ispat Nigam Limited), there are variances of a cross-section from 65-320 sq.inches. Having a huge variety of special grades available in steel billets and steel blooms, detailed list can be viewed in the given link: https://us.assteels.com/wp-content/uploads/2020/02/Billets.pdf
Product Manufacturing Process
Iron Ore is a major raw material of this product. This iron ore is melted in the furnace, the liquid material so obtained is then poured into CCM (continuous casting machine). The continuous casting machine is then making the Billets of required cross-section and length. Steel Billets are generally made with mild steel with a density of 7.85gm/cm3. At the same time, special grades are also available.
Billets and blooms generally act as a feedstock for commercial Steel products like bars, rods, tubes, pipes, wire, and wire products. These products are extruded from Billets and Blooms into the fine end products with the help of a continuous rolling process and thermo-mechanical treatment, where applicable. Billets also have direct usage in the manufacture of products that go into CNC machines, military weapons, lathes, steel building vehicles, and so on.
In steel classes, the chemical composition and its allowed range are prescribed, and they significantly affect thermo-physical properties of steel, e.g. the thermal conductivity, specific heat, density, enthalpy, contractility, and viscosity. Chemical composition varies according to the grades of billets. Its major components are Carbon, Manganese, Phosphorous, Sulfur, Silicon, Aluminium, Chromium
Note: The Chemical composition changes according to the grades of billets and blooms. https://us.assteels.com/wp-content/uploads/2020/02/Billets.pdf
