Diagram note: SS440C martensitic stainless steel that can be heat treated to provide a wide range of hardness value. The first procedure for heat treated involves austenitizing process by heating the sample at 1150°C for 60 min, follow heating again at 1100°C for 30 min, quenched the sample produced martensitic structure. Higher austenitizing temperature was sufficient to transform the steel into austenite and to form martensite phase upon quenching. The second procedure involves tempering process. To exam the tempered martensite and ferrite phase the tempering temperature was chosen varied between (400-700)°C for 1 hr.
