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.
Sheet steel with a width of more than eight inches, with a thickness ranging from one quarter of an inch to more than one foot (see Sheet Steel).
Industry:Metals
Fabrication technology in which fine metallic powder is compacted under high pressure and then heated at a temperature slightly below the melting point to solidify the material. Primary users of powder metal parts are auto, electronics and aerospace industries.
Industry:Metals
A small group of stainless steels with high chromium and nickel content, with the most common types having characteristics close to those of martensitic (plain chromium stainless class with exceptional strength) steels. Heat treatment provides this class with its very high strength and hardness. Applications for PH stainless steels include shafts for pumps and valves as well as aircraft parts.
Industry:Metals
Involves sawing plate (primary aluminum plate products) into square or rectangular shapes to tolerances as close as 0. 003 of an inch.
Industry:Metals
A blast furnace enhancement to reduce an integrated mill’s reliance on coke (because of environmental problems with its production). Up to 30% of the coke charged into the blast furnace can be replaced by this talcum-like coal powder, which is injected through nozzles at the bottom of the furnace.
Industry:Metals
The cutting of holes into carbon steel beams or plates by pressing or welding per customer specifications.
Industry:Metals
Modified basic oxygen furnace in which the oxygen and other gases are blown in from the bottom, rather than from the top. While the Q-BOP stirs the metal bath more vigorously, allowing for faster processing, the design produces essentially the same steel grades as the top-blowing basic oxygen furnace. Today’s state-of-the-art furnace design combines the previous technologies: 60% of the oxygen is blown from above, with the rest blown through the bottom of the vessel.
Industry:Metals
The testing required for a new process adopted to make certain grades of steel with exacting end uses. In order for the process to become qualified, the steel made by the process must be tested.
Industry:Metals
A process of hardening a ferrous alloy of suitable composition by heating within or above the transformation range and cooling at a rate sufficient to increase the hardness substantially. The process usually involves the formation of martensite.
