Abstract

In this report the implant cracking test was applied as a cold cracking test for basic 0.1% carbon steels alloyed with nickel, chromium, molybdenum or manganese. The microstructures and maximum hardness in Vickers hardness test in the heat-affected zone were investigated. The delayed crack occurred in the 0.1%C basic steels which contained alloying element more than about 5% in Ni, 4% in Cr, 1% in Mo or 2% in Mn. The maximum hardness in the heat-affected zone at which the delayed crack occurred was more than about 300 to 350. The microstructure of the heat-affected zone of the steels in which the delayed crack occurred mainly showed a bainitic and martensitic structure without primary ferrite along the prior-austenite boundary.
