The main disadvantage of grey cast irons, regarding the mechanical properties, is the notch effect caused by the flakes of graphite. A model proposed to describe the grey cast irons is a steel with cavities filled with graphite. If this lamellar graphite is transformed into spheroidal graphite, ...
Generally speaking, steel shafts are less expensive than graphite shafts, so the same set of clubs will cost less with steel shafts vs. graphite shafts. In a set of irons, that price difference is often around $100 (more as the total cost of the set goes up). Of course, that has to...
A general material description of “Steel” or “Brass” is too broad. • Often cast iron is specified. Gray cast iron is brittle in tension and cracks in cold weather. Select an appropriate cast iron, such as spheroidal graphite cast iron, which has the strength of mild steel. UTS 320...
PURPOSE: To produce a high-speed steel series cast iron material low in a friction coefficient and in which the progress of cracks is hard to occur and to provide a composite roll whose outer layer is formed by the cast iron material. ;CONSTITUTION: The graphite-crystallized high-speed steel...
Further, the friction welded member can be obtained by applying friction welding to the mutually friction-weldable graphite cast iron members or to the friction weldable graphite cast iron member in which the adverse effect of graphite is prevented and a steel material.;COPYRIGHT: (C)1999,JPO ...

Electrodes are classified as regular grade or premium grade on the basis of their physical properties (International Iron and Steel Institute, 1983). Charge carbon Charge carbon is used in the EAF to consume excess oxygen during melting and to minimise the oxidation of alloys. Different carbon ...
In vermicular graphite cast irons, graphite is present in a worm-like, stubby form with rounded edges. This material is also popularly known as compacted graphite cast iron or as CG iron. Cast iron with vermicular graphite falls between cast iron with lamellar graphite and cast iron with sphero...
