Terminology 3. The strip is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly. These elements are considered as incidental and are not normally reported. The amount of reduction is greater than that used in skin-rolling see 3. It is intended for deep drawing applications where such surface disturbances are not objectionable.

The production of speci? In bright normalizing the furnace atmosphere is controlled to prevent oxidizing of the strip surface. It serves to reduce the tendency of the steel to? It is also used to impart surface? The tempers are obtained by the selection and control of chemical composition, by amounts of cold reduction, by thermal treatment, and by skin-rolling.

No. 4 Temper Strip Steel

Mead Metals, Inc. We can support quantities to accommodate both high-volume and low-volume needs. It is highly formable, depending on temper, and is useful in a wide range of applications. Our Minimum Order Quantity policy enables us to suit metal product orders of all sizes. Additional variables apply depending on material thickness, width, and additional processing. A cold rolled strip steel—along with the other metal products carried by Mead Metals—is processed by a metal slitter. We have multiple slitting machines, and we use them to obtain specific tolerances for customer orders.
