1) Remark: EN-GJS-500-7 (before GGG-50 acc. to DIN 1693-1 : 1973-10), a ferritic-pearlitic cast iron with nodular graphite for cast parts of static and dynamic load in vehicle manufacturing, in construction trade and plastics processing, in machine tool construction, in machine engineering, in fitting manufacturing, energy machine engineering. For brake casings, brake pads, axle housings, pressure tubes, tunnel ring segments, shutoff damper for fittings, cases and plugs for ball valves, centrifugal breaker, conveying screws, gear boxes, pole wheels for generators, crank shafts, fly wheels, hubs, chain wheels, eccentric wheels, gear wheels, ring gears. This cast iron mark applies to specimen made by machining of separately cast samples. The material is comparable to UNS F 33100 from the USA. The fracture toughness of this make accounts for 25 MPa*m^1/2 (information value). The fatigue strength (Woehler- rotating bending test) accounts for the unnotched specimen (diameter: 10,6 mm) 224 N/mm², for the notched sample 134 N/mm² (unnotched specimen: For annealed ferritic cast iron with nodular graphite (GGG) the fatigue strength approximates the tensile strength x0,5 (Rm) of GGG with a Rm of 370 N/mm². The rate decreases according to the increasing Rm so far until fatigue strength for perlitic and tempered GGG approximates Rm x0,4. The rate continues to increase if the Rm exceed 740 N/mm². Notched specimen: For a sample of 10,6 mm diameter at the notch and a circumferential 45°- V-notch at a radius of 0,25 mm the fatigue strength of annealed GGG increases to a value of the fatigue strength x approx.0,63 of unnotched samples of GGG with a Rm of 370 N/mm². This value decreases according to the rising Rm of ferritic GGG. For GGG of intermediate strength values and for perlitic GGG and for tempered GGG the fatigue strength of notched samples approximates fatigue strength x0,6 of unnotched samples). Ferrite-pearlite is the predominant structure.
