Estado de Suministro:

Caractersticas de fabricacinASTM A-36 (NTC 1920)Es un acero usado en construcciones de estructuras metlicas, puentes, torres de energa y edificaciones remachadas, atornilladas o soldadas. Tambin se emplea en cerrajera y sealizacin.Este acero dada su alta soldabilidad, permite ser unido con cualquier tipo de electrodo revestido de acero al carbono.ASTM A-572 (NTC 1985)Es el acero de calidad estructural de alta resistencia y baja aleacin, al Columbio (Niobio) o Vanadio. Es empleado en la construccin de estructuras metlicas, puentes y torres de energa, edificaciones remachadas, atornilladas o soldadas.Con el propsito de obtener una unin de igual o mayor resistencia que el acero base, deben utilizarse electrodos de mnimo 70.000PSI de resistencia a la tensin y preferiblemente de bajo hidrgeno.
