UNF FGE42-12 is a ductile iron (SG iron) material grade used in Spain. It is equal to EN-GJS-450-10 in European standard EN 1563.

The followings are the chemical composition and mechanical properties for EN-GJS-450-10 ductile cast iron.

Chemical Composition:
According to all international material standards, the chemical composition should not be taken as the inspection standard, unless the clients have special requirements. However, by our experience, the approximate chemical components of ductile iron EN-GJS-450-10 should be as C: 3.50-4.00, Si: 2.20-2.90, Mn: 0.3-0.6, P: 0.03-0.06, S: 0.02-0.040, Mg: 0.020-0.060.

Mechanical Properties:
Tensile Strength ≥ 450 MPa.
Yield Strength ≥ 310 MPa.
Elongation ≥ 10%.
There is no strict stipulation to the hardness of GJS-450, however, normal hardness range should be 160 - 210 BH (Brinell Hardness).

Applications for FGE42-12 Ductile Cast Iron:
Our Dandong Foundry normally use FGE42-12 ductile cast iron to produce exhaust manifolds, dental chair brackets, cradle brackets, gas valve parts, gas compressor parts, security parts for low temperature applications, etc.
