In October of this year, My Chinese customer Mr J. visited one north Asia country,he visited our old friends, and also discussed our business in north Asia. Mr. J is an old friend of OTAI Steel and had steel distributor in Moscow. Mr. J’s company has regularly purchased tool steel Cr12MoV from us in recent years. From this visit, we learned that his company also purchased 42CrMo4 steel, but from Europe. Regarding 42CrMo4 steel, we did not discuss too much in that meeting because the quality issues were mentioned.

After returning home, I provided a formal quotation to Mr. J. He found the price is attractive but still no further action. Then I shared the SGS report and on-site inspection photos. That night, I received his email. He tell me according to the report, the material we sent to the Saudi Arabia project is not Q + T, the tensile strength must be min 1000 MPA, and the two thermal data are lower than 1000 MPA. Mr. J is very professional in this area. He previously worked as an engineer at. I am not an engineer and cannot explain at this moment, but I believe there is no problem with our 42CrMo4 steel.
