This invention adopts common alloying element Cu,Cr,Mn to carry on low alloying for nodular iron and utilizes the cast afterheat for quench. Its final organization takes the bainite as main body and is added with small quantity of martensite, residual austenite and carbide. Its hardness is HRC42-56. The prodn. cost of the said nodular cast iron is low, service life is long, and prodn. technology is simple and convenient. It is suitable to popularize on the prodn. of sand mould cast flow line and metal mould cast. |
