Реферат: ABSTRACT A coil of pre-lubed steel strip has a steel strip substrate coated on each surface with a uniform coating of solid lubricant. The coating has a coating weight greater than 20 mg/ft.2 (0.22 g/m2) for lubricity during cold deforming of the strip, as by stamping or drawing. The coating weight is less than 100 mg/ft.2 (1.08 g/m2) to prevent slippage during operations incident to blank-ing of the strip prior to cold deforming. The coating has a needle penetration hardness in the range 9-250. Various procedures for applying the coating are de-scribed.
