A higher aluminium-titanium balance separates Incoloy 800HT Round Bar from its 800H sibling — more creep strength, same corrosion resistance.
Whatever designation your specification cites, Incoloy 800HT Round Bar meets it — tested, certified and fully traceable.
Aluminium and titanium give Incoloy 800HT Round Bar its age-hardening edge — strength that grows with controlled heat treatment.
