To research in do Research Center Metallurgy And Materials-LIPI, developed steel superior quality of a nickel (limonite). Called that, limonite this produce through iron ore deposits agreement that is the top layer of saprolit (nickel ore high levels). With processing content through its own limonite innovation, the development of done lipi it produces the nature of steel superior. To find out more about steel laterite excellence , conducted research on the influence of the element of laterite inside steel .By increasing the mechanical properties of micro and structure with the process of heat treatment (quenching and tempering) can increase the power of attraction test , test and test impak violence and change micro structure. The power of attraction highest test occurs in the process of quenching water and tempering ?y 1272 N/mm2 and ?u 1281 N/mm2. Test on energy impak of the largest in absorbency normalizing and hot rolling 1200^0 C. Test on violent quenching having the hardness of water highest 50,26 HRC. And change the micro structure.} }
