A story about my client

We have a customer from central Asia wants to make instruments. The suitable material he learned is AISI 4340, but the customer does not confirm, so he wants us to recommend it to him. But since they’re terminals, it’s best to stick with the materials they’re used to. So I recommend AISI4340 to the customer, but I mentioned that it would be better to use the E19 steel . Also I gave the customer the quotation.

The customer is not sure about the quality and wants to buy a little. I  Say yes to the client. But it is better to ship by FCL quantity to save the freight. The customer is interested in continuing to communicate with me. Otai company has a good reputation both in China and abroad. Some clients place an order to us through the introduction of friends. We not only provide the E19 steel plate but also provide technical support. because my boss has more than 16 years of experience in the steel industry. Welcome to send me an inquiry for more details about the E19 steel plate.

Our company could supply the 4140 pre hardened steel plate, but also the steel in other different conditions, like annealed, Milled bright surface. For this steel plates, we keep daily 1000Tons in our stock. So we are the largest stockist in south of China for this 4140 steel plates.

Recently, I got the inquiry from my customer. His company is mainly for the die and tool producing. So he use a lot of tool steel. And our company could provide the one stop solution service. So customer needs us to cut and mill the 4140 pre hardened steel plate into each flat bar for them.

Normally, when we make the cut and mill flat bars, we will proceed it based on the closed thickness steel plates. For example, if you need the milled surface in 13mm thickness, we will make it based on the 16 mm thickness black surface steel plates. We will not cut and mill it based on the very thick blocks. As we all know, when produce the very thick blocks, the price cost will be more higher. And the quality will be not such stable in thick blocks. And moreover, when make it into milled flat bars, the output capacity will be very small if cut based on the block.

For the 4140 pre hardened steel plate, it has high fatigue limit and resistance to multiple impacts. And its low-temperature impact toughness is good.The 4140 in Q+T is widely used to produce various components,such as:bolts. High-strength bolts, wind power bolts, prestressed anchors, post-stressed anchors, steel tie rods, tie rods, tension rods etc. Shafts: shafts, crankshafts, sleeve shafts, linear shafts, pump shafts, rotor shafts, spline shafts, transmission shafts, screw shafts, etc.

OTAI is the stable and reliable supplier for Fortune 500 companies at home and abroad. Such as Thyssenkrupp and China North Industries Group. They placed the repeat order to us very often because of the guaranteed quality.

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.
