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”.
A633GrD steel plate is suitable for normalized high-strength low-alloy structural steel plate for tower connection or source bolt connection structure. A633GrD steel plate should be normalized: heat the steel plate to a suitable temperature that can produce austenite structure but does not exceed 1700F [925℃], and keep it at this temperature for a period of time, so that the entire stal S460QL plate can be uniformly heated, and then left in the air Cool with medium.
As the thickness and hardness of stal S460QL increase, the tendency to crack at the cutting edge increases. In order to prevent the stal S460QL from cutting cracks, preheating should be carried out before stal S460QL cutting. Special attention should be paid to preheating to make the entire stal S460QL interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole stal S460QL cannot be preheated, the partial preheating method can be used instead.
