What is S690QL thickness standard

ASTM A514 steel is mainly used in places where high tensile strength and high yield are required, such as engineering vehicle lifting gears, large excavators, offshore platforms, etc. Different grades of A514 steel plate have different thickness, chemical composition and properties. However, the S690QL thickness mechanical properties specified in ASTM A514 are similar to those of Q690 in China. A514 grade Q is generally used as the rack for offshore platform. Its hardness is between 230-390MPa, yield is greater than 630MPa, and tensile strength is more than 700MPa.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the S690QL thickness and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

Established in 2014, Steel Safety Day was set up to reinforce awareness of the five most common causes of safety incidents and to create a safer working environment across the entire steel industry worldwide. By focusing every year on the five causes - moving machinery, working at heights, falling objects, on-site traffic and S690QL thickness process safety incidents - worldsteel intends to set up a continuous improvement process and reiterate its commitment to the safety and health of the people who work in the S690QL thickness industry.

At present, the inventory of S690QL thickness in some markets is still at a low level, the rhythm of late arrival can be controlled, and the inventory pressure of agents is small; secondly, the orders of steel mills are basically saturated, the ex factory price is obvious, and the short-term S690QL thickness price support is strong. On the whole, the cost side is high, the inventory pressure is not big, and S690QL thickness traders are cautious and optimistic. Although the short-term demand persistence still needs to be considered, the overall price bottom is supported. It is expected that China's S690QL thickness prices will fluctuate at a high level tomorrow.
