Vv. Kalmykov et Iy. Grechnaya, THE EFFECT OF HEAT-TREATMENT ON THE CORROSION-RESISTANCE OF CARBON-STEEL U8, Protection of metals, 28(5), 1992, pp. 581-585
We investigated the corrosion behavior of steel U8 in different struct
ural states under conditions of hydrogen (1 N solution of H2SO4) and o
xygen (3% solution of NaCl) depolarization. The article shows that the
technology of thermal strengthening has a substantial effect on the c
orrosion resistance of steel With comparable hardness (strength) lamel
lar structures of decomposition of austenite, originating with isother
mal transformations in a wide range of temperatures, prove to be corro
sively more active than the structures of hardening and tempering with
granular (globular) cementite.
