A full selection of specialized steel grades designed to optimize performance of motors, transformers,

generators and other electrical equipment. Highly advanced steels specially formulated for porcelain or vitreous coatings in branded appliances. Simple, straight-from-the-mill hard sheet steel for end uses that require limited bending/forming. All backed by an industry-leading steelmaking expertise and a steel-strong commitment to customer success.

This is cold-rolled coil steel from U. S. Steel.

Cold-Rolled Coil Products

Motor Lamination Sheet

BENEFITS

We help our customers power the future. Motor lamination steel by U. S. Steel is a specialized cold-rolled sheet product manufactured with properties that maximize the performance of electro-magnetic core materials used in electrical equipment components. Motor lamination steels minimize energy losses from the electrical energy input into motors.

FEATURES

Our motor lamination sheets are cold rolled, below its recrystallization temperature, which enables better control over the product shape, thickness, dimensions and surface finish.

We manufacture a range of steel grades where the primary distinguishing feature is a specified Core Loss requirement. Each grade is supplied in the semi-processed, un-annealed condition and must be annealed after punching the laminations to develop optimum magnetic properties.

VITRENAMEL™ Steel

BENEFITS

Home appliances are more than an essential part of our homes. They’re an essential part of life. VITRENAMEL™ Steels by U. S. Steel optimize the application of porcelain or vitreous enamel coatings and are manufactured with specialized properties that can achieve both good formability and enhanced aesthetics. Our steel products are cold rolled, producing a high quality finished surface to exceed our customers' requirements.

FEATURES

U. S. Steel produces three grades of steel that optimize the application of porcelain (or vitreous) enamel coatings that (1) resist fish-scaling during the enameling process, (2) resist carbon boil during enameling, and (3) provide the sag resistance needed during the firing process.

All VITRENAMEL™ grades typically are furnished with a rough matte finish to improve adhesion of the enamel coating. The approximate surface roughness is 55 to 90 micro-inches. A rougher surface finish, 90 to 150 micro-inches, can be provided if required for a specific application.

The dimensional tolerances for VITRENAMEL™ Steel Sheet products are the same as those for Cold Rolled Steel Sheet as established by ASTM.

Full Hard Sheet

BENEFITS

Cold-rolled full hard unprocessed sheet by U. S. Steel is the option to choose for applications that require very limited bending and/or roll-forming.Supplied directly from the cold-reduction mill without any annealing to soften the steel, our full hard sheet is highly work-hardened and exhibits a high resistance to denting, with only minimal ductility. The hardness is Rockwell B 84 minimum.

FEATURES

Since the product is supplied directly after cold rolling without further processing, our full hard cold-rolled unprocessed sheet is not subject to the same product standards that have been established for other cold-rolled sheet products.We provide it with a matte or smooth surface finish produced on the cold reduction mill.
