Carbon |
| As the principal hardening element in steel, increasing the carbon content increases the steel's hardness. The tensile strength also increases up to approximately 0.85% carbon. Ductility and weldability decrease as the carbon content increases. The principal carbon range for Erisco product is 1008 (.10% max) to 1065 (.60/.70%) with 1008 being the most common. |

Tensile Strength |
| The maximum load per unit of original cross-sectional area obtained before rupture of the tensile sample (before it breaks). This figure is expressed in pounds per square inch (psi). |
| |
Continuous Coil |
| A full coil of wire as it is drawn from the rod. the weight can very depending on wire diameter and customer specifications. A typical Erisco continuous coil weight is 1000-2500 pounds. |
| |
Catchweight Coil |
| A continuous coil broken down into smaller coils. The weight of the coil can vary above or below the specified weight. The most common Erisco catchweight coil size with ranges from 25 to 100 lbs. |
| |
Black Annealing |
| Performed by heating coils of wire in a furnace and cooling in a manner to allow annealing to occur. Erisco can produce black annealed in any size from .062" to .750". Erisco black annealed is generally produced from 1008 carbon wire with a 60,000 psi max tensile after annealing. |

Galvanized Wire |
| Produced by passing single strand wire through a bath of molten zinc or through an electrolytic cell containing a solution of zinc salt. |
| |
Basic Wire |
| Wire produced by conventional drawing practice with no finish. |
| |
Straightened and Cut Wire |
| Produced from coils by means of special machinery which straightens the wire and cuts it to specific lengths. |
| |
Finishing Process |
| Great Lakes Metal Finishing provides automatic zinc rack and barrel lines. Additional services such as pickling, etching, baking and vibratory deburring are available. |
