EN-GJL-200 is a low grade gray cast iron according to the German standard DIN EN 1561, it can also be written as EN-JL1030, 0.6020 or GG20 according to the new DIN 1691 standard.
EN-GJL-250 is a high quality gray cast iron material in European standard EN 1561, it is also called GG25 cast iron in DIN 1691 by Germany and Austria.
These are the chemical composition, mechanical properties and equivalent grades of cast iron EN-JL1050 (EN-GJL-300), including its tensile strength, elongation, test resistance and hardness, according to the UNE-EN 1561 standard.
Ductile iron EN-GJS-400-18 is defined in the founding standard EN1563: 2011. Spheroidal Graphite Cast Irons, There are three grades: EN-GJS-400-18 LT, EN-GJS-400-18 RT and EN-GJS-400-18. LT means low temperature; RT for room temperature.
EN-GJS-500-7 is medium grade ductile cast iron in European standard DIN EN 1563, its equivalent grade in DIN 1693 is GGG50.
It offers reasonable machinability and excellent surface finish combined with higher wear resistance, strength and response to heat treatment compared to EN-GJS-500-7. Noise and vibration damping is good to this degree. Com-pairs with EN (-1563-GJS) -600-3 (GGG60 and Meehanite SP600).
