Abstract

The separation behavior of low-pearlite niobium-alloyed structural steels has been investigated as a function of coiling temperature. Starting material was controlled rolled hot strip, which was cooled from finish rolling temperature to coiling temperature of 600 and 470 degree C. The formation of stable Nb(CN) compounds in hot strip can be suppressed by lowering the coiling temperature to 470 degree C. During isothermal aging above 550 degree C, finest incoherent precipitates are formed in the ferritic matrix through a coherent phase. This state exhibits high strength data with good strain data.
