Specimens of 00Cr16Ni5Mo low carbon martensitic stainless steel were normalized at 1000 deg. C followed by tempering at 525 deg. C, 550 deg. C, 575 deg. C, 600 deg. C and 625 deg. C. After heat treatment, mechanical properties and pitting potential were determined through tensile, impact and electrochemical polarization tests. The results showed that the samples tempered at 550 deg. C and 600 deg. C for 2 h had an excellent combination of tensile strength, elongation, impact energy, hardness and corrosion resistance. Scanning electron microscopy, and X-ray diffraction examinations were conducted. These revealed that the properties of the steel were affected by the structure of the lath martensite, {delta}-ferrite, retained austenite and carbides.
