"Other individual elements or other totals": The chemical composition includes elements not specified in the table. Analysis should only be conducted if these elements are suspected to be present, or if routine analysis suggests that their content may exceed the prescribed limits.

• Sand, chill, centrifugal and continuous casting
• The customer can request that in the delivered block, (% Ni) = (% Fe) + 1; castings with this composition show no selective corrosion in warm seawater.
