Baja tuang paduan rendah nuduhake baja tuang paduan kanthi kandungan karbon kurang saka 0,45% lan isi total unsur paduan liyane ora ngluwihi 5%. Low alloy cast steel nduweni kekuatan dhuwur, kateguhan apik lan hardenability. Baja tuang paduan rendah umume ngemot unsur paduan kayata mangan, kromium, tembaga, nikel, molibdenum, lan vanadium. Dheweke duwe kateguhan sing luwih gedhe lan bisa entuk sifat mekanik sing luwih apik liwat perawatan panas. Ing resistance karat lan nyandhang resistance baja cast alloy kurang luwih saka baja karbon, kang bisa nyuda bobot saka bagean lan nambah urip layanan.
