AS 1831 GRADE 500-7 is a ductile iron material grade used in Australia. This material has medium strength and toughness and good machinability.
Our Dandong Foundry normally use AS 1831 GRADE 500-7 ductile cast iron to produce many kinds of cast iron brackets, plow points, belt pulleys, carrier wheels, cushion blocks, iron gaskets, etc.
The Chemical Properties of AS 1831 GRADE 500-7 Ductile Cast Iron:
Normally, the clients will not require the chemical composition, and in international standards, such as ISO 1083, ASTM A536, DIN 1693, UNI 4544 and AS 1831, there are no mandatory stipulation to the chemical composition. Actually, from different standards, their suggested chemical compositions are very different, but all of them denoted that the chemical composition should just be reference, and will not be taken as quality inspection standard.
Of course, if you need to stipulate the chemical composition to meet the special application, then you should denote the allowable chemical element range on the drawings or in your requirements.
