Definitions

  • the invention relates to a process for producing seamless line pipes within the quality grade range X 52 to X 90.
  • tungsten As an alloying element, it is regularly used to produce cold-work, hot-work and high-speed steels. It increases their high-temperature strength, ability to withstand tempering and, in particular, the wear resistance at high temperatures. Tungsten acts in a similar way to molybdenum, so that it can replace molybdenum in a ratio of 2:1.
  • ferritic alloys containing 9 to 12% chromium which are able to withstand high temperatures are used for steam pipelines.
  • Examples of such steels are the alloys P 92 and P 122 from Japan and the European-developed material E 911.
  • the object of the invention is to propose a method for the production of seamless line pipes, in which method it is possible to reliably set a quality grade in the range from X 52 to X 90 by means of a quenching and tempering treatment and to ensure a stable yield strength combined with an essentially constant stress-strain characteristic up to temperatures of use of 200° C.
  • this object is achieved by hot-rolling of a pipe blank made from a steel of the following composition (% by weight): C 0.06-0.18% Si max. 0.40% Mn 0.80-1.40% P max. 0.025% S max. 0.010% Al 0.010-0.060% Mo max. 0.50% V max. 0.10% Nb max. 0.10% N max. 0.015% W >0.30-1.00%
  • the nitrogen content it is recommended to add up to 0.050% Ti to the steel alloy used.
  • the tungsten content expediently lies in the range from 0.35 to 0.70%, particularly preferably in the range from 0.35 to 0.40%. It is recommended to set the vanadium content at at least 0.04%.
  • the steel alloy which is to be used for the hot rolling according to the invention may perfectly well contain further accompanying substances, such as those which are used in particular for electric-furnace steelmaking, without its properties being impaired.
  • accompanying substances are copper, chromium and nickel.
  • the steel should contain at most 0.15% of each of these accompanying substances.
  • a line pipe which has been hot-rolled and quenched after reheating according to the invention can be set at any desired quality grade within the range from X 52 to X 90 by means of quenching and tempering.
  • the toughness properties are improved by increasing the tempering temperatures.
  • a line pipe which is produced according to the invention has a stable yield strength at least up to a temperature of use of 200° C., i.e. the reduction in yield strength is very low ( ⁇ 10%).
  • the stress-strain characteristic is essentially constant.
  • the weldability, which is important for line pipes, is guaranteed.
  • the carbon equivalent according to IIW can be set at relatively low levels.
  • the molybdenum content can be limited to very low values or may even be zero. Since tungsten is less expensive than molybdenum, the alloy which is to be used according to the invention costs less to produce.
  • the carbon equivalent values for the comparison steel were 0.44 and 0.24, respectively.
  • the alloy of the steel used according to the invention differs from the comparison alloy essentially only in that the molybdenum content is 0.15% lower, and an additional content of 0.35% tungsten is added instead.
  • the yield strength of the steel used according to the invention fell by only approx. 5%.
  • the stress-strain characteristic in FIG. 1 surprisingly the stress-strain curves at room temperature (RT) and at the test temperature of 160° C.
  • the use of higher tempering temperatures makes it possible to reduce the strength level, while lower temperatures increase the strength level.
  • Within the limits of the alloying ranges according to the invention it is possible to select alloys which, by means of appropriate quenching and tempering treatment, can produce the quality grade range from X 52 to X 90. In terms of the notched-impact strength at a test temperature of ⁇ 30° C.
  • the tested steel specimen according to the invention achieved a notched-impact energy value of 92 J/cm 2 , which is regarded as extremely good for the quality grade X 85.
  • the weldability of the steel according to the invention can be classified as entirely satisfactory, and there is no evidence of the addition of tungsten to the alloy having any adverse effect.
