Definitions

  • ABSTRACT Tubes and vessels intended for use in handling or housing hot water are formed by welding together sheets of stainless chromium steel having high corrosion resistance, good workability and completely stabilized structure.
  • the present invention shows the way and proposes the means for rendering it possible to manufacture heat exchangers and the like as described above also of chromium steel and to meet the requirement of a longest possible service life.
  • a heat exchanger or the like referred to above is made of sheet metal, of a material having the general chemical composition as follows:
  • Chromium steel with low carbon and nitrogen contents which improves the working properties.
  • the material is stabilized with titanium, which improves the corrosion resistance.
  • the chromium steel further includes molybdenum, which in combination with the low carbon and nitrogen contents eliminates the disadvantages of conventional chromium steels, such as brittleness and corrosion.
  • Welded installations in contact with hot or warm water according to above, for example water heaters or heat exchangers, according to the invention are characterized in that they consist of sheets of chromium steel having the analysis as follows:
  • a heat exchanger of usual construction was manufactured by welding cold-rolled sheets of 2 mm thickness with the steel analysis as follows: Carbon 0.028 nitrogen 0.025 chromium 18.95 nickel 0.35 copper 0.06 silicon 0.5 manganese 0.48 and molybdenum 2.44 and titanium 0.64
  • An article comprising at least one welded sheet of stainless chromium steel consisting essentially of C not more than 0.03%
  • the balance being iron and incidential impurities, percentages being by weight.
  • alloy steel composition includes also a significant amount of a carbonand nitrogen-binding stabilizing element selected from the group consisting of niobium, tantalum, aluminum and zirconium.
