Definition
|
| S.A.E. - Society of Automotive Engineers |
The SAE number ascribed to certain alloys represents the limitations and/or requirements of various alloying elements in the material. |
| Salamander |
A solidified mass of iron, usually with slag inclusions, from the bottom of a furnace. |
| Sample |
A small representative amount of a larger quantity. |
| Scale |
The oxide of iron that forms on the surface of steel after heating. |
| Scarf |
To remove by torching, shaving or grinding surfaces of a piece of semifinished steel.
Also, the material so removed, called "scarfings." |
| Schedule |
A system whereby scrap is shipped in a manner and at a rate deemed desirable by our customers and/or ourselves. If scrap is to be scheduled, both buyer and seller should be made aware of that possibility, as it becomes a part of our contractual responsibility. |
| Scrap (Ferrous) |
Ferrous (iron-containing) material that generally is remelted and recast into new steel. Integrated steel mills use scrap for up to 25% of their basic oxygen furnace charge; 100% of the mini-mills' raw material for their electric furnaces generally is scrap.
Home Scrap. Waste steel that is generated from within the steel mill, through edge trimming and rejects. It normally is sent directly back to the furnace.
Prompt (Industrial) Scrap. Excess steel that is trimmed by the auto and appliance stampers and auctioned to scrap buyers as factory bundles. This is a high-quality scrap as the result of its low-residual content and consistent chemistry.
Obsolete Scrap. Iron-bearing items such as old automobiles; household appliances; farm, office and industrial equipment; ships and railroad cars; buildings and bridges that have completed their useful life which can be recovered from the junkyard and remelted.

| Scrap Substitute |
Raw material that can be charged in place of scrap in electric arc furnaces and basic oxygen furnaces. Scrap substitutes include, among others, DRI, HBI, iron carbide, and pig iron. |
| Second Movement |
If a carload/bargeload/truckload of material is rejected and is reshipped to a second consumer, it is considered a second movement of that vehicle, and care must be taken that all costs involved in the first movement become a part of the records connected with the second movement. (see "Reship.") |
| Secondary Steel |
Steel that does not meet the original customer's specifications because of a defect in its chemistry, gauge or surface quality. Mills must search to find another customer (that can accept the lower quality) to take the off-spec steel at a discount. While secondary will not affect the reported hield, margins will suffer. |
