Definitions

  • the balance consists of Fe and inevitable impurities.
  • one or more selected from Nb and Cu are selected elements as follows. You may contain in the range of.
  • Nb 0.01 to 0.15%
  • Nb forms and fixes carbonitride with C and N, and has the effect of enhancing corrosion resistance, formability, and intergranular corrosion resistance of welds, and also significantly increases high-temperature strength to improve thermal fatigue characteristics and high-temperature fatigue. It is an element having the effect of improving the characteristics. In order to acquire the effect, containing 0.01% or more is preferable. However, if the content exceeds 0.15%, Nb is an expensive element and also raises the recrystallization temperature of the steel. Therefore, it is necessary to increase the annealing temperature, leading to an increase in production cost. Therefore, when Nb is contained, the amount is preferably in the range of 0.01 to 0.15%. More preferably, it is in the range of 0.02 to 0.12%. More preferably, it is in the range of 0.05 to 0.10%.
  • B 0.0002 to 0.0050%
  • B is an element that improves workability, particularly secondary working embrittlement.
  • the content is preferably 0.0002% or more.
  • the content exceeding 0.0050% lowers the workability and toughness of steel. Therefore, when B is contained, the content is preferably in the range of 0.0002 to 0.0050%. More preferably, it is in the range of 0.0002 to 0.0030%. More preferably, it is in the range of 0.0002 to 0.0010%.
