certification, remember that iron is the element that composes the majority of the chemical values listed. (See Exhibit I attached) Steels can be cast to shape, or the cast ingot or strand can be reheated and hot worked by rolling, forging, extrusion, or other processes into a wrought mill shape. Wrought steels are the most

of the conventional ingot teeming process by cast-ing steel directly into semifinished shapes. The casting, rolling, and steel finishing processes are also used in iron and steel manufacturing. Hot steel is transformed in size and shape through a series of hot rolling and forming steps to manufacture semifinished and finished steel products.

Our 10" x 10", 10" x 20" and 12" x 30" rolls are alloy cast with a Brinell hardness of 400. They are cast with nickel, chrome, molybdenum, magnesium and iron. Tempering (flame hardening) which warps lower quality rolls is not required. The rolls are thick enough to be re-corrugated 6 to 8 times before they must be replaced.

steel ingots, like high-speed steel, cannot be cogged satisfactorily in a rolling mill and these qualities are, therefore, hammered, whatever the ingot size. Low-alloy cons-tructional steels are generally roll-cogged. The operation accomplishes a reduction in the cross-section, a refinement of the struc-ture and shaping of the metal in a ...
4140HW combines medium carbon content with high-end chromium, molybdenum, and manganese contents to improve hardenability. We add trace amounts of vanadium to increase temper resistance. Other residual elements are also added, but controlled within AISI4140 standard limits. A grain structure enhances toughness at all strength levels.
