J. Storesund et R. Sandstrom, INFLUENCE OF POST WELD HEAT-TREATMENT ON IMPACT TOUGHNESS PROPERTIES OF 1CR0.5MO AND 2.25CR1MO STEELS, Steel research, 66(3), 1995, pp. 117-123
The influence of post weld heat treatment on hardness and impact tough
ness properties of weldments of 1Cr0.5Mo and 2.25Cr1Mo steels has been
investigated. Post weld heat treatment significantly reduced the hard
ness and the impact transition temperature and increased the upper she
lf energy. The decrease in hardness was essentially larger for 2.25Cr1
Mo than for the other steel, probably due to the presence of martensit
e in the as-welded condition in the former material. The decrease in t
he impact transition temperature was largest for 1Cr0.5Mo.
