Description

EN-GJN-HV600 consists of eutectical carbides of types M7C3 and M3C (M=Fe, Cr) in a matrix, which contains mostly martensite and sometimes bainite and austenite. The comparable G-X 300 CrNiSi 9 5 2 acc. DIN 1695 : 1981-09 (invalid) is characterised by a high wear resistance and applicable at moderate impact stress. The wear resistance increases with the carbon content while the impact resistance decreases. The correlation between thickness of cast iron and chemical composition exist: - Thickness of cast iron up to 25 mm: Si:1,90%, Mn:0,40%, Ni:4,5%, Cr:8,5% - Thickness of cast iron > 25 bis 50 mm: Si:0,40%, Mn:0,50%, Ni:3,8%, Cr:2,0% - Thickness of cast iron > 50 bis 100 mm: Si:1,80%, Mn:0,50%, Ni:5,0%, Cr:9,0% - Thickness of cast iron > 100 mm: Si:1,60%, Mn:0,60%, Ni:5,5%, Cr:9,5%.. For thicknesses far 100 mm it is recommended to increase the Ni-content. Cast parts made of cast iron with 5 % Ni and 9 % Cr are mostly delivered under heat treated conditions.
