The delamination problem of S690Q steel plate

We received new order from Myanmar's Navy. It is about S690Q steel plate AH36 marine grade steel plates, which will be used to build ships. This is the third time we supplied marine grade steel materials for Myanmar's Navy. This time a new delegation team came to visit us and spoke highly about our production lines and our marine grade steel plates performance supplied S690Q steel plate to Myanmar's Navy before. Both of us expects a pleasant cooperation.

Our technical department plays important role in our professional communication with customers, especially those who have high technical requirements for steel materials and those who need complex further processing. Under such condition, our technician department can provide technical support in time, anylize customer design or make drawing according to customer needs rapidly, so that we can proceed smoothly. The profession of our team has won great praise of customers.

Some S690Q steel plate, low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating. Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum. The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures.

The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related S690Q steel plate products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our S690Q steel plate products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
