The inventory declines of a573 gr 65 structural steel plate have slowed down significantly

Low alloy structural steel, also known as ordinary low alloy steel, HSLA steel.
a573 gr 65 structural steel mild plate, Low alloy steel plates are killed or semi killed steel plates. Low alloy steel plates have the advantages of high strength, better performance, saving material and reducing the weight of structure. The thickness range of low alloy steel plates is usually 4.5-200mm. Low alloy structural steel is mainly used for manufacturing bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc.

The Lanzhou Natural Gas Transmission and Distribution Project (Peak-shaving Gas Storage and Supply Station) project is an emergency gas storage project constructed to implement the construction of the national natural gas production, supply, storage and marketing system to ensure the natural gas demand of the local government. The Lanzhou Natural Gas Transmission and Distribution Project has completed 80% of the total engineering volume.

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 a573 gr 65 structural steel mild plate 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.

a573 gr 65 structural steel mild plate and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.
