Corus Service Centres can supply a range of carbon and alloy steels in bar form as well as grey and spheroidal graphite (SG) cast iron for a huge variety of general and specialist engineering applications. Manufacture Carbon Steel Of low to medium carbon content, these products are rolled from a billet to a "black" bar of the finished size. This can be converted to "bright" bar either by cold drawing, turning or grinding. Alloy Steel Composition is selected with end use specifically in mind but, in addition to the elements commonly found in steel, there may be chromium, molybdenum and nickel, singly or in combination. After rolling to the required size, these steels can be hardened e.g. by oil quenching, followed by a temper heat treatment or annealing to achieve the required balance of strength and toughness. Cast Iron Continuously cast and rolled to the required size. Key Features Carbon Steel -
Used where higher tensile properties than those of mild steel are required but the expense of using an alloy steel would not be justified -
Available as rounds, squares, flats and hexagons -
Available in either black or bright finish -
Good level of dimensional accuracy (Bright bar) -
Has good machinability Alloy Steel -
Used in situations where higher strength is required in combination with an enhanced level of toughness, e.g. where an ability to resist shock loading, or additional wear resistance is needed. As a result, it is more difficult to machine than carbon steels -
Commonly available as rounds, but also as squares, flats and hexagons. Available either in black or bright finish Cast Iron -
Characterised by good machinability because of the self-lubricating qualities arising from the presence of graphite. (Flake graphite in grey iron) -
SG iron combines high strength, ductility and toughness. -
Retains strength at high temperature -
Absorbs vibration better than steel -
Good surface finish For more information about the range of sizes and specifications available please download the PDF of the Stock Range & Specifications booklet. |
