		abstract={National demand for steel is increasing every year and always filled with soft steelproduction produced by Krakatau steel where the raw material is imported from Brazil.
For the LIPI successfully developed a superior quality steel from low-grade nickel ore (limonite). Mentioned that, this Limonite diproleh through lateritic nickel ore deposit
which is the top layer of saprolite (high grade nickel ore). With the processing of limonite content through its own innovation, development by LIPI produces superior
properties of steel. To find out more about the advantages of steel laterite, conducted a study of the influence of laterite elements in the steel, mechanical properties, microstructure and its application in industry. To find capable for such steel, Heat Treatment process is then performed. After the heat treatment, in testing how they affect the microstructure and
mechanical properties of the steel. Tests conducted in this study a impact test, hardness test and metallographic test.
From the test results it was known that the chemical composition% Mn steels 1:40, 1:10% Cr nearly accordance with ASTM A 541 / A 541M-95 (1999) used for Piping,
Pressure Vessel and Components}
