Definitions

  • the steel according to the invention is produced by casting, Rolling, normalizing or by normalizing rolling and accelerated cooling.
  • the titanium content of the steel according to the invention preferably to 0.01 to 0.02% and the nitrogen content to 0.005 to 0.008% with one Titanium: nitrogen ratio of preferably 2.0 to 4.0 fixed. Under this condition, the most effective hindrance to austenite grain growth in Welding achieved with high heat input.
