SJK-400.3 is a low grade of ductile cast iron in Norway standard NS11 301. The matrix of this grade is fully ferritic with high ductility and impact strength.
It is equal to EN-GJS-400-18-LT in European standard EN 1563.
The Chemical Properties of NS11 301 SJK-400.3 ductile cast iron
In standard NS11 301, there is no requirement to the chemical composition, so the iron foundry could adjust their chemical composition as their experience, as long as their material could meet the mechanical properties.
