Overview

Research examines mechanical degradation and creep damage in furnace tubes, indicating critical material limitations.

Key Points

  • This research aims to investigate the mechanical property deterioration and creep damage in AISI 1020 steel furnace tubes used in petrochemical environments.
  • Conducted microstructural observations and mechanical property tests on AISI 1020 steel furnace tubes after 20 years of service at 218 °C.
  • Measured hardness and ultimate tensile strength at various temperatures including room temperature, 600 °C, and 650 °C.
  • Hardness of the lower section of the tube was below 140 HV 0.3 due to grain size effects.
  • Ultimate tensile strength decreased by 18.93% at room temperature, 23.56% at 600 °C, and 6.93% at 650 °C compared to new tubes.
  • Creep behavior revealed that steady-state creep rate increases with temperature, leading to reduced creep life.
