In industrial development, especially in the machine ability, metallurgy is very important about metal selection witch have mechanical or physical properties witch is suitable with production. Wider of metal product is push the designer and metallurgy expert to have ability to choose on what metal is refine the metal properties, witch is also include the corrosion resistance. In this research, heat treatment is variation by the temperature. Is at specimen 1 with temperature 650 Derajat C, holding time 40 minute and water cooling media, specimen 2 with temperature 750 Derajat C, holding time 40 minute and water cooling media, specimen 3 with temperature 850 Derajat C, holding time 40 minute and water cooling media, specimen 4 with temperature 950 Derajat C, holding time 40 minute and water cooling media. The temperature was choose because, at this temperature the chromium carbide precipitation will appear. After the heat treatment process, it is continued with corrosion test by immersing the specimen into sulfuriC acid (H2SO4). From the research, it is gain that: at temperature 650 Derajat C the corrosion rate (mpy) is 2,80522326, at temperature 750 Derajat C the corrosion rate (mpy) is 12,6235047, at temperature 850 Derajat C the corrosion rate (mpy) is 21,0391745, at temperature 950 Derajat C the corrosion rate (mpy) is 8,41566979, and at non heat treatment the e corrosion rate (mpy) ;s1,40261163


Di dalam perkembangan indusrti, terutama dalam bidang permesinan, metalurgi memegang peranan penting dalam pemilihahan logam yang memiliki sifat - sifat mekanik maupun fisik yang sesuai dengan tuntutan produksi. Semakin luasnya tuntutan produksi logam ini, maka sileap perancang desain dan ahli metalurgi harus mampu untuk menentukan pilihannya terhadap logam yang memperbaiki sifat - sifat logam diantaranya adalah sifat tahan korosi yang baik. Dalam penelitian ini dilakukan proses perlakuan panas dengan variasi temperartur, yaitu pada spesimen 1 dengan T = 650 Derajat C holding time 40 menit dan media pendingin air. spesimen 2 dengan T = 750 Derajat C holding time 40 menit dan media pendingin air. spesimen 3 dengan T = 850 Derajat C holding time 40 menit dan media pendingin air. spesimen 4 dengan T = 950 Derajat C holding time 40 menit dan media pendingin air, sebab pada temperature ini presipitasi karbida akan terbentuk. Kemudia dilanjutkan dengan mencelupkan spesimen ke dalam larutan asam sulfat H2SO4. Dari hasil penelitian didapatkan : Pada temperatur 650 Derajat C laju korosi (mpy) adalah 2,80522326, Pada temperatur 750 Derajat laju korosi (mpy) adalah 12,6235047, Pada temperatur 850 Derajat C laju korosi (mpy) adalah 21,0391745, Pada temperatur 950 Derajat C laju korosi (mpy) adalah 8,41566979, dan pada kondis; non heat tretment laju karos; (mpy) adalah 1,40261163
