42CrMo4 Plate Annealed might just a carbon steel?

A new customer asked about 42CrMo4 Plate Annealed today,It’s thankful that market seems going tobe recover.

I want 42CrMo4 Plate Annealed in German quality

But the second email about 42CrMo4 Plate Annealed,it kind of made me upset.As there is not thing question about the steel technology or knowleage.Only said I am worry about the defect of Chinese steel,I want the German quality.

Of course,I have to admit that German steel quality is quite well,and all over people are know it,I guess.

Why he bought a terrible one

I talked more with him,and foud the reason,that he such worry about the quality problem,he bought a terrible batch from China,but the real reason is that he thought that all steel from China should be very cheap.

So he did tried his best to achieved the unreasonable prices,the price of 42CrMo4 Plate Annealed,even lower 20% than us.So I guess what he got just a carbon steel before.

Technical data of 42CrMo4 Plate Annealed

Finally,I told him, no matter you will purchased from China again,Remember 2 thing.

No.1 never think there are something crazy cheap price,espcial much lower than market price.it will make you pay for lesson.

No.2 Check the chemical data about the goods,if you can,to check the company own direct-reading spectrograph,than if would be much safe.
