Definitions

  • Patent Document 3 listed below discloses a pre-coated brazing coated metal sheet produced by suspending a Ni-based brazing material together with an organic binder, spray-coating it on the surface of a stainless steel plate, and heating.
  • Patent Document 5 C: 0.5% or less, Si: 2% or less, Mn: 3% or less, S: 0.2% or less, Ni: 8-18%, Cr: 12-25%, Mo : 0-4%, W: 0-2%, (Ni / Cu): 2 or more, Nb: 0-2.5%, substantially exhaust gas recirculation made of austenitic stainless cast steel Parts are disclosed.
  • the EGR cooler acidic condensed water composed of sulfuric acid, nitric acid, and organic acid is generated due to SOx, NOx, and HC contained in the exhaust gas.
  • the exhaust gas is directly under the engine and in front of the catalyst, and the exhaust gas before purification is targeted. Therefore, the acid concentration of the generated condensed water is also high.
  • the sulfuric acid concentration in the condensed water also increases.
  • Such an increase in acid concentration leads to a decrease in pH, and it is said that the pH of condensed water in the EGR cooler reaches about 1.5.
  • the plate thickness of the heat exchanging part of an EGR cooler is as thin as 0.1 to 0.5 mm, so that excellent corrosion resistance is required in a condensate having a pH of about 1.5 consisting of sulfuric acid, nitric acid, and organic acid. .
  • C + N 0.015% or more
  • C + N is set to 0.015% or more from the viewpoint of suppressing the strength decrease accompanying the coarsening of crystal grains during brazing.
  • C + N is desirably 0.02% or more. Since excessive addition of C and N reduces intergranular corrosion resistance and workability, it is desirable that C + N is 0.04% or less.
  • Ni (Ni: 3% or less) Ni can be contained in an amount of 3% or less as required in order to improve the corrosion resistance. It is 0.2% or more that a stable effect is obtained. However, excessive addition deteriorates processability and increases the cost because it is expensive. Therefore, it is preferable to contain 0.2 to 3%.
  • the wetting spread is “Good (good)”, and when the brazing area is less than twice The wetting spread was evaluated as “Bad (defect)”. Thereafter, the cross-sectional microstructure was observed. Then, the number of crystal grains existing in the plate thickness direction is measured over a range of 20 mm in length in parallel with the rolling direction, and the microstructure is “Good ( “Good” ”, the one having only one was evaluated as having a microstructure of“ Bad (defect) ”.
