A514 Gr P QT steel plate,45# steel is a common medium carbon quenched and tempered structural steel. The cold plasticity of 45# steel is general. Annealing and normalizing are slightly better than quenching and tempering 45# steel has higher strength and better machinability After proper heat treatment, 45# steel can obtain certain toughness, plasticity and wear resistance 45# steel is suitable for hydrogen welding and argon arc welding, not suitable for gas welding,A514 Gr P QT steel plate.
A514 Gr P QT steel plate,The Seamless Pipe Q345D to Thailand. In November of 2015, Thailand OTTO group contacted with us from Internet. They are finding the trustable supplier of S355/2H seamless pipe for the cable car supporter. Due to the special using of the pipes, they are very careful and serious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and products quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1800 tons pipe to us directly.

A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.
When phosphorus, copper, chromium, nickel and other trace elements are added to the weathering steel sheet, a dense and strong adhesion protective film will be formed on the steel surface, which will hinder the corrosion from spreading and developing inside, and protect the substrate under the rust layer, so as to slow down the corrosion rate. That is why the weathering steel sheet has good atmosphere corrosion resistance.
we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.
