SJK-500 is a middle grade of ductile cast iron in Norway standard NS11 301. It offers good tensile strength and a satisfactorily high yield point combined with good toughness.
The Chemical Properties of NS11 301 SJK-500 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.
