FNG70-2 is a type of high tensile strength ductile cast iron (SG cast iron, nodular cast iron) material grade in Belgium standard NBN 830-02.
It has comparatively high tensile strength, and good abrasive resistance. So, this cast iron grade is suitable to produce mechanical parts with high duty.
Our Dandong Foundry has been producing this material grade for many years, and herein, we share its chemical composition, mechanical properties and its worldwide equivalent grades.
Chemical composition of NBN 830-02 FNG70-2 ductile cast iron
According to the standard NBN 830-02, the cast iron foundries could adjust the chemical composition by themselves as long as the mechanical and physical properties of the castings could meet the requirements in standards.
