造方法である。It has a high expansion side alloy plate made of Fe alloy containing one type of Mo 4wt%~6wt% on one side, and NL35wt%~50wt% or Cr13Wi%~1
After finishing the two- or three-ply bimetal plates having a low-expansion side alloy plate made of an Fe alloy containing 8 wt% on the other side by pressure bonding, identification etching is applied to one side of the bimetal plates. This bimetal manufacturing method is characterized by performing a treatment of immersing the mark in a passive film forming liquid as a treatment to prevent the mark from discoloring and becoming unclear due to subsequent aging treatment in the atmosphere.

られる。In the present invention, for example, after forming an identification etching mark on one side of the bimetal plate, the temperature is 15°C to 5°C.
By immersing the bimetal in a passive film forming solution at 0°C for 1 to 30 seconds to form an ultra-thin passive film on the surface of the bimetal, the material can be easily aged in the atmosphere following stamping. This prevents the surface from discoloring to deep blue, making the etching marks clear and making it easy to identify the material.
