AK Steel Corporation is an American steel company whose predecessor, Armco, was founded in 1899 in Middletown, Ohio. Today, the company's corporate headquarters is situated in West Chester, Ohio, (a suburb of Cincinnati) after having moved from Middletown, Ohio, in August 2007.[3]
AK Steel offers a diverse product line unmatched by any other competitor in the market. Our flat-rolled carbon, stainless and electrical steels meet and exceed specifications of the world's most demanding customers in the automotive, appliance, construction and manufacturing markets.
AK Steel is the premier producer of automotive carbon and coated steels as well as stainless steels for automotive exhaust system components. Our stainless steels also go into applications like appliances, food processing equipment, chemical and petrochemical equipment and industrial equipment. AK Steel is the only full-line domestic producer of energy efficient electrical steels for power generation, power and distribution transformers, lighting systems and electric motors.
AK Steel is on the leading edge of technology with one of the largest steel research centers in the country. We work closely with customers and potential customers to develop innovative products and applications like our Black Coat™ stainless steel, developed to improve the cosmetic appearance of visible automotive exhaust components while withstanding the increased temperatures of modern engines.
Our subsidiary AK Coatings, Inc. offers carbon and stainless steels coated with the AgION antimicrobial compound. AgION products hold the potential for use in food contact applications along with heating, ventilating and air conditioning equipment (HVAC), medical equipment, laboratories, home appliances and more, anywhere microbial growth is a concern
Hot Rolled Steels
Our Hot Rolled steels are produced in a wide variety of grades that meet the strictest chemistry and dimensional requirements in the market today and have excellent strip surfaces. Consistency from coil to coil is maintained by applying ladle metallurgy and continuous casting to molten steel, plus rolling on a modernized 80" wide hot strip mill - the only one in the domestic industry equipped for pair-cross rolling - that features on-line roll grinding, work-roll bending and automatic gauge control. These technologies enable AK Steel to meet the most demanding customer specifications for hot bands, hot rolled sheet coils, cut- and mill-edge coils, plus cut lengths and custom blanks.

Cold Rolled Steels
AK Steel's Cold Rolled steel products are known for excellent surface quality and press formability, tight tolerances, and the widest widths available in the industry produced at our Rockport Works. We manufacture low- and ultra-low-carbon grades to meet a variety of customer formability requirements, including CS Type B, DS Type B, EDDS, and EDDS+. AK Steel also produces HSLAS and Structural Steel grades for those applications that require specified strength levels. Cold Rolled steels can be specified as Dent Resistant or Bake Hardenable for applications that require dent resistance after forming and painting. Each grade can be processed with several surface finishes depending on customer requirements. Lubricants can be applied to enhance formability and to avoid at-press lubrication.

Hot Dip Galvanized Steels
AK Steel's Hot Dip Galvanized steels, commonly known as ZINCGRIP®, are continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc. Zinc protects the base metal by providing a barrier to corrosive elements and also by the sacrificial nature of the coating. ZINCGRIP is available in the widest widths in the industry, with special surface finishes, tailored for specific applications, and in a variety of base metal grades and coating weights. The broad range of grades available includes CS Type B, DDS, EDDS, and EDDS+, and can be specified as Bake Hardenable or Dent Resistant. ZINCGRIP is also available with phosphate bonderized. ZINCGRIP is widely used in many applications in the automotive, appliance, construction, HVAC, and other industries. AK Steel pioneered a high quality surface for exposed automotive applications.

Hot Dip Galvannealed Steels
AK Steel's Hot Dip Galvannealed Steels, called ZINCGRIP® GA, are continuously coated on both sides with a zinc-iron alloy. Galvannealed steels are a specialized variation of galvanized steels where induction heating is used to alloy the zinc coating with the steel to create a zinc-iron coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and coating. This process results in a material with the strength and formability of steel plus the corrosion protection of the zinc-iron coating. Zinc protects the base metal by providing a barrier to corrosive elements and also by the sacrificial nature of the coating. ZINCGRIP GA is available with special surface finishes, tailored for specific surface applications, and in a variety of base metal grades and coating weights. ZINCGRIP GA is widely used in many applications in automotive and general manufacturing.

Enameling Products
AK Steel manufactures three enameling products to meet a variety of porcelain enameling and formability requirements: UNIVIT®, VIT-PLUS®, and I-F® Enameling Steel. These products are manufactured specifically for use in the appliance, plumbingware, and other industries. Enameling Steels provide the best enamelability, formability, surface finish, and gauge and flatness tolerances. They can be provided with different surface finishes depending on customer specification or part requirements. Oil-based or acrylic/polymer lubricants can be supplied to enhance formability and/or to avoid at-press lubrication.

Coil Coated Products
Continuous coil-coating with a wide range of organic coatings results in products with the properties of steel plus enhanced appearance, corrosion protection and fabrication characteristics. Cold rolled, aluminized, electrogalvanized, hot dip galvanized, galvannealed, terne and hot rolled can all be coil-coated to exact customer specifications.
Oriented Electrical Steels
Oriented electrical steels are iron-silicon alloys that were developed to provide the low core loss and high permeability required for more efficient and economical electrical transformers. Available in grades M-2, M-3, M-4 and M-6, with superior magnetic properties in the rolling direction, oriented steels are used in transformer cores. They are used in large generators and other apparatus when the design permits the directional magnetic characteristics to be used efficiently. The AK Steel Technology Center continues to develop new and improved grades to provide the electrical industry with core materials for the manufacture of more efficient electrical apparatus.

TRAN-COR® H
TRAN-COR H high-permeability electrical steels offer an outstanding degree of grain orientation. The result is far lower core loss than possible with conventional grain-oriented electrical steels. These "super-oriented" materials provide higher permeability, particularly at higher operating inductions, and the potential for producing less noisy core structures due to lower magneto-striction. Laser scribing TRAN-COR H electrical steels provides additional beneficial core loss reductions through domain refinement. A highly focused Nd:YAG laser beam is used to rapidly scan material surfaces perpendicular to the rolling direction. They are available in grades H-O and H-1.

Nonoriented Electrical Steels
Nonoriented electrical steels are iron-silicon alloys in which magnetic properties are practically the same in any direction in the plane of the material. Standard grades from M-15 to M-47 are available, with the advantages of special DI-MAX processing that enhances the magnetic properties. Material is available Fully Processed as well as Semi-Processed, depending on grade. DI-MAX grades have superior permeability at high inductions, low average core loss and good gage uniformity. In addition, cold finishing plus strip annealing produce a smooth surface and reduce buckles and waves, resulting in excellent flatness and a high stacking factor. Applications include large and small motors, large and small transformers, generators, lighting ballasts and ignition coils.
