Definitions

  • quality level N 80 is neither required nor guaranteed that the product, when used in media containing hydrogen sulfide, generally has sufficiently reliable resistance to stress corrosion cracking.
  • quality level L 80 is prescribed for use under sour gas conditions according to API, which has limited technological properties compared to quality level N 80 and a limitation of hardness to a maximum of HRC 22 and a remuneration structure.
  • the tempering consists of quench hardening and subsequent tempering. The high expenditure of energy and time for the treatment and reworking of the product is perceived as a disadvantage.
  • the invention is based on the above steel alloy and the production of pipes therefrom. It has set itself the task of selecting alloy ranges and conducting the heat treatment in such a way that a fine-grained ferritic pearlitic structure is produced which has comparable stress corrosion cracking resistance to that of tempered structure with comparable yield strengths.
  • the current proposal avoids the subsequent quenching and tempering and specifies an alloy selection for a steel that cools in air from the hot shaping heat and, if necessary, undergoes normalization treatment during the hot-rolling process and fulfills requirements for a narrow yield strength range as well as for high resistance to hydrogen-induced stress corrosion cracking.
  • the result is a simplified production of a product for use in an atmosphere containing hydrogen sulfide.
  • a steel with which thus falls under the composition mentioned in claim 1 has been heated to the rolling temperature of 1250 ° C. and then rolled to the tube dimensions of 139.7 x 7.7 mm. Before the last rolling section, the temperature was reduced to below 550 ° C until the grain was completely granulated and then heated again to a rolling temperature of 920 ° C. After the finish rolling, air was cooled from the rolling heat.
  • the strength values are as follows:
  • the hardness was HRC 23 and the average grain size was ASTM 10.
