Abstract

Esitetään törmäyksen- ja murtumankestävä teräs runkorakenteeseen. Fe:n ja väistämättömien epäpuhtauksien lisäksi teräs edelleen käsittää seuraavat alkuaineet massaprosenttiosuuksina: C: 0,06-0,12 %, Si: 0,05-0,60 %, Mn: 1,30-1,70 %, Al: 0,01-0,06 %, Ti: 0,005-0,012 %, Mg: 0,0005-0,003 % ja 0 < Ca ≤ 0,004 %, jossa 0,0005 % ≤ Ca + Mg ≤ 0,004 %. Lisäksi edelleen esitetään menetelmä törmäyksen- ja murtumankestävän teräksen valmistamiseksi runkorakenteeseen, käsittäen vaiheet: (1) sulatus ja jatkuva valu; (2) kuumennus; (3) ohjattu valssaus; (4) ilmajäähdytys; ja (5) normalisointikuumennuskäsittely: normalisointilämpötila säädetään arvoon Tq, jossa Tq = 945 – 11 C – 14 Mn – 17√Cr + 16√Mo, jossa kukin alkuaine korvataan lukuarvolla, joka on ennen prosenttimerkkiä alkuaineen sisällössä massan perusteella, ja normalisointilämpötilan yksikkö on °C; pitoaika säädetään arvoon Th, jossa Th = 1,5 x t min-yksikössä, jossa t edustaa teräslevyn paksuutta mm-yksikössä.
