19 Guidelines for Ferrous Scrap INSTITUTE OF SCRAP RECYCLING INDUSTRIES, INC. Copyright © 2022 Institute of Scrap Recycling Industries, Inc. Guidelines for Ferrous Scrap: FS-2022 General Information a. Cleanness. All grades shall be free of dirt, nonferrous metals, or foreign material of any kind, and excessive rust and corrosion. However, the terms “free of dirt, nonferrous metals, or foreign material of any kind” are not intended to preclude the accidental inclusion of negligible amounts where it can be shown that this amount is unavoidable in the customary preparation and handling of the particular grade involved. b. Off-grade material. The inclusion in a shipment of a par- ticular grade of iron and steel scrap of a negligible amount of metallic material which exceeds to a minor extent the applicable size limitations, or which fails to a minor extent to meet the applicable requirements as to quality or kind of material, shall not change the classification of the shipment, provided it can be shown that the inclusion of such off-grade material is unavoidable in the customary preparation and handling of the grade involved. c. Residual alloys. Wherever the term “free of alloys” is used in the classifications given herein, it shall mean that any alloys contained in the steel are residual and have not been added for the purpose of making an alloy steel. Steel scraps shall be considered free of alloys when the residual alloying elements do not exceed the following percentages: Nickel .45% Molybdenum .10% Chromium .20% Manganese 1.65% The combined residuals other than manganese shall not exceed a total of 0.60 percent. d. Deviations. Any deviations from the general classifi- cations of iron and steel scrap may be consummated by mutual agreement between buyer and seller. 200 No. 1 heavy melting steel.
