What is the Q355GNH beam steel corten plate material as rolled delivery state

The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, Q355GNH beam steel corten plate material professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better Q355GNH beam steel corten plate material tomorrow!

SA516Gr60 meets the requirements of (ASME) ASTMA516/A516M standards, and meets the needs of oil gas with high content of sulfur and hydrogen, reducing sulfur and hydrogen corrosion, reducing equipment maintenance, and increasing equipment life. The steel Q355GNH beam steel corten plate material has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-layer cracking performance, microalloying, high purity, low carbon equivalent, and strong resistance to sulfur and hydrogen.

It has good toughness. By strictly controlling the chemical composition, reducing the content of Q355GNH beam steel corten plate material harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, Q355GNH beam steel corten plate material using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.

The basic principle of Q355GNH beam steel corten plate material, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

The toughness of steel such as Q355GNH beam steel corten plate material is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
