Continuous casting nozzle deflector

. . A continuous casting nozzle includes a deflector at a bottom portion of the nozzle having a bore extending through the deflector from an open end to a closed end along a longitudinal axis and a pair of ports extending through the deflector from the bore to an outer surface of the deflector. A diameter of the bore substantially rapidly decreases along the longitudinal axis above the pair of ports such that a portion of a flow of fluid through the deflector becomes detached from a surface of the bore to thereby redirect the flow of fluid toward the longitudinal axis prior to exiting through the pair of ports.. ...

Press hardened steel with increased toughness and method for production

A method for processing a press hardenable steel includes first heating a slab of the press hardenable steel. The slab is heated to a re-heat furnace temperature of approximately 2300° f. ... Ak Steel Properties Inc

Grain oriented electrical steel with improved forsterite coating characteristics

Increasing the chromium content of an electrical steel substrate to a level greater than or equal to about 0.45 weight percent (wt %) produced a much improved forsterite coating having superior and more uniform coloration, thickness and adhesion. Moreover, the so-formed forsterite coating provides greater tension potentially reducing the relative importance of any secondary coating.. ... Ak Steel Properties Inc

Surface modification of stainless steels

A process involves the continuous surface treatment of stainless steel coils with aqueous suspensions of rare earth oxide nano or micro particles or aqueous rare earth nitrate solutions of nano or micro particles. The surface treatment can be applied by roll coating, spraying or other conventional application techniques. ... Ak Steel Properties Inc

Weld wheel cleaning system

A weld wheel cleaning system is provided to clean or remove a layer of embedded material and other debris produced from welding from the working surface of a weld wheel. Such a weld wheel cleaning system includes a cleaner with an abrasive material positioned on an outer surface of the cleaner. ... Ak Steel Properties Inc

High elongation press hardened steel and manufacture of the same

The residual ductility of currently available press hardened steel is approximately six percent. This characteristic of the material is primarily due to the fully martensitic microstructure in the hot stamped condition. ... Ak Steel Properties Inc

Tundish funnel

A continuous casting machine is provided that includes a refractory tundish funnel. The tundish funnel has a tapered shape and is designed to sit on a tundish lid in order to channel steel from the ladle to the tundish bath. ... Ak Steel Properties Inc

Method for extending the campaign life of stabilizers for a coating line

A steel processing line includes a dip tub and a stab roll. The dip tub is filled with a quantity of molten metal. ... Ak Steel Properties Inc

Warm rolling of steels containing metastable austenite

Warming a metastable steel before or during cold rolling suppresses the transformation of austenite to martensite, resulting in lower mill loads and higher amounts of reduction at similar loads. As-warm rolled steel has enhanced mechanical properties when compared to steel reduced the same amount by cold rolling. ... Ak Steel Properties Inc

Composite steel

To improve the stiffness of a thin single layer or mono-sheet of steel, a composite steel comprising at least two outer steel layers separated with a spacer. Spacer materials can include any metal less dense than steel, or a polymer or resin, optionally comprising a carbon or glass fiber, or kevlar material. ... Ak Steel Properties Inc

High formability dual phase steel

To improve the formability of dual phase steels, the martensite phase is tempered. It may form a ferrite-carbide structure. ... Ak Steel Properties Inc
