Ferritic is the second-largest class of stainless steel, constituting approximately 25% of stainless production. Ferritic stainless steels are plain chromium steels with no significant nickel content; the lack of nickel results in lower corrosion resistance than the austenitics (chromium-nickel stainless steels). Ferritics are best suited for general and high-temperature corrosion applications rather than services requiring high strength. They are used in automotive trim and exhaust systems, interior architectural trim, and hot water tanks.

Ferro Alloys

A metal product commonly used as a raw material feed in steelmaking, to aid various stages of the steelmaking process such as deoxidation, desulfurization, and adding strength. 


Ferrous is the term used to indicate the presence of iron in a metal and will also be used to distinguish iron and steel from non-ferrous metals.


An iron cleaning agent. Limestone and lime react with impurities within the metallic pool to form a slag that floats to the top of the relatively heavier (and now more pure) liquid iron.


This is a way of producing individual metal parts by mechanical impact. It is suitable for working a wide range of steels, and can be done with the metal cold, warm or hot. The metal changes shape while in a solid rather than molten state making it quite different to a casting process. Forgings are used principally where strength and in-service integrity are key requirements. They are stronger than cast or machined parts because the mechanical deformation allows the grain structure of the metal to closely follow the part’s finished shape. There are a number of forms of forging which involve containing the metal workpiece to a greater or lesser degree. The starting material may be steel bar, billet or ingot, and this is often sourced externally from steelmakers.

Free-Cutting Steel

Free-cutting steel is used for making engineering components and is most commonly supplied to the machinist as hot rolled, cold drawn, turned or precision ground bar. It has certain properties during mechanical machining operations like drilling, turning and milling. 

Full Hard

A full hard steel refers to a cold rolled sheet steel that has not been softened by annealing
