SJG150 is a low material grade of gray cast iron defined in Norway standard NS11 100, it is also equaled to cast iron GG15 in standard DIN 1691 by Germany and Austria.
The lower grade of grey iron mainly used for applications where strength is not essential, such as counterweights, crane balls, stove parts, etc.
The followings are the general properties, mechanical properties, thermal properties and electrical properties for GG15 gray cast iron, which should be equal to SJG150 in standard NS11 100.
