KE40 offshore steel sheet standard pdf

The capital letter H in S355J0H and S355J2H stands for ""Hollow section"", which respectively represents the pipe of S355J0 and S355J2.
The Executive Standards of S355J0 steel and S355J2 steel, are both EN 10025-2, the difference is that they have different temperature requirements for impact energy: S355J0 - impact energy at 0 ℃ is required to be ≥ 27J. S355J2: impact energy at - 20 ℃ is required to be ≥ 27J.
The company adheres to the "variety, quality and efficiency" road We have established a technology center, a brand cultivation management system and a quality control system Now the company has formed an independent innovation system integrating production, learning, research and marketing Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification,KE40 offshore steel sheet.Quenching is a common heat treatment process. It is the metal heat treatment process in which the metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
KE40 offshore steel sheet,With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of steel material.
