The main form of S690QL1 hardness and its application

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 S690QL1 hardness 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 S690QL1 hardness 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 S690QL1 hardness industry.

S420NL-Z35 steel plate is alloy structural steel, and it implements the European standard EN 10025-3. The chemical composition of S420NL-Z35 steel plate: C:≤0.2, Si:≤0.6, Mn: 1 - 1.7, P:≤0.025, S:≤0.02. Delivery state of S690QL1 hardness, S420NL-Z35 steel plate: quenching + tempering. Of course, the delivery status can also be selected according to specific demands. However, it needs to be communicated between the supplier and the demander and indicated in the contract.
