Effect of Controlled Rolling on Mechanical Property and Microstructure of Nb Microalloyed H Beam

Abstract:

Precipitated phase of microalloyed H beam was analysed by TEM and electrolyzation. Effect of heating temperature on austenite grain size and solid solution of Nb in steel and effect of finishing rolling temperature on property of tested steel were studied. According to the results, controlled rolling process was determined to produce the hot-rolled. Property of H beam includes that yield strength is 410MPa~430MPa, and charpy impact energy at -20°C is greater than 50J. The ferrite grain size number is 11. All of the properties are up to the American Petroleum Institute standard of H beam for offshore platforms.
