SJK-700 is a type of high tensile strength ductile cast iron (SG cast iron) material grade designed in Norway standard NS11 301.
It has comparatively high tensile strength, and good abrasive resistance. So, this cast iron grade is suitable to produce press and stamping machine dies, highly stressed machine components, toothed wheels, running wheels and crankshafts.
The Chemical Properties of NS11 301 SJK-700 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.
