Harsoinen teräs is the third and final album of Hassisen Kone, released in 1982. Musically, the album has a progressive twist to it. The songs are more complicated than on the group's two previous albums, and the band's lineup was expanded to seven people for this album, featuring a new guitarist Jukka Orma (who later continued with Ismo Alanko in Sielun Veljet), saxophonist Antti Seppo, keyboardist Safka Pekkonen and percussionist Hannu Porkka.
