Stringer (slag) : ウィキペディア英語版 | Stringer (slag) Stringers are filaments of slag left in wrought iron after the production process. In their correct proportions their presence is beneficial, as they help to control the ductility of the finished product, but when the proportion of slag is too high, or when the filaments run at right angles to the direction of tension, they can cause weakness. ==Manufacture== Wrought iron is no longer made. The particles of slag present in the iron after preparation by puddling were drawn into long fibres during the forging or rolling process. The proportion of slag was intended to be about 3%, but the process was difficult to control and examples with up to 10% slag were produced.
