Michelle Applebaum Research is a Chicago-based equity
research consulting firm founded by Michelle Applebaum,
formerly a Managing Director of Salomon Brothers. The
company provides consulting expertise in the area of steel
and steel equities to institutional investors and industry.
Pipe made from a solid billet, which is heated, then rotated under extreme pressure. This rotational pressure creates an opening in the center of the billet, which is then shaped by a mandrel to form pipe.
Industry:Metals
Steel that does not meet the original customer’s specifications because of a defect in its chemistry, gauge or surface quality. Mills must search to find another customer (that can accept the lower quality) to take the off-spec steel at a discount. While secondary will not affect the reported yield, margins will suffer.
Industry:Metals
Steel shapes — for example, blooms, billets, or slabs — that later are rolled into finished products such as beams, bars, or sheet.
Industry:Metals
A catchall name for an operation that buys steel, often processes it in some way and then sells it in a slightly different form. A service center is distinguished from an end-user by the fact that, unlike an end-user, a service center sells steel, not a fabricated product. Service centers are manufacturers to the extent that they add labor to steel by providing a service.
Industry:Metals
If the edges of sheet and strip are not controlled during reduction, they must be trimmed parallel by shears. This process may be performed by either the steel mill or steel processor to match customer needs.
Industry:Metals
Thin, flat-rolled steel. Coiled sheet steel accounts for nearly one-half of all steel shipped domestically and is created in a hot-strip mill by rolling a cast slab flat while maintaining the side dimensions. The malleable steel lengthens to several hundred feet as it is squeezed by the rolling mill.
The most common differences among steel bars, strip, plate, and sheet are merely their physical dimensions of width and gauge (thickness).
Industry:Metals
Fist-sized, homogenous pieces of old automobile hulks. After cars are sent through a shredder, the recyclable steel is separated by magnets. Mini-mills consume shredded scrap in their electric arc furnace operations.
Industry:Metals
A type of specialty steel created by introducing silicon during the steelmaking process. Electrical steel exhibits certain magnetic properties, which make it optimum for use in transformers, power generators, and electric motors.
Industry:Metals
The metal’s grain runs parallel within the steel, permitting easy magnetization along the length of the steel. Although grain-oriented steel may be twice as expensive to produce, its magnetic directional characteristics enable power transformers, made from this metal, to absorb less energy during operation.
Industry:Metals
Because there is no preferential direction for magnetization, non-grain-oriented steel is best used in rotating apparatus such as electric motors.
