Mill Continuous tin-plating facility to produce tin mill steel sheet to be used in food and beverage cans and other containers. The thickness of the coating is readily controlled through regulation of the voltage and speed of the sheet through the plating area. Because it is used in food cans just like tin plate, it ironically is classified as a tin mill product. Tin-free steel is easier to recycle because tin will contaminate scrap steel in even small concentrations. Tin Plate Thin sheet steel with a very thin coating of metallic tin.
Tin plate is used primarily in canmaking.
Tolerances A customer's specifications can refer to dimensions or to the chemical properties of steel ordered. The tolerance measures the allowable difference in product specifications between what a customer orders and what the steel company delivers. There is no standard tolerance because each customer maintains its own variance objective. Therefore, another steel mill or service center will slit, roll, coat, anneal, or plate the metal for a fee. Tool Steels Steels that are hardened for the use in the manufacture of tools and dies.
