ASTM A709 high strength steel,In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel supplier in the world.
ASTM A709 high strength steel,P355GH is the European standard pressure vessel plate and sheet. The implementation standard: EN10028-2:2003. , EN P355GH steel plate and sheet has good plasticity, toughness, cold bending performance and welding performance, suitable for manufacturing nuclear island steel containment, pressure vessels, equipment structural parts, etc. It is delivered in hot rolled, normalized + tempered condition.
ASTM A709 high strength steel,Weathering steel has good resistance to atmospheric corrosion Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel 15-2 times Therefore, weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent,ASTM A709 high strength steel.
Ultrasonic flaw detection emits ultrasonic waves to the steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.ASTM A709 high strength steel
Q345 and Q345B are steel numbers The differences are as follows:1 Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B2 Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃)3 Q345 does not indicate carbon content of steel; Q345B carbon content is 020%Q345 refers to carbon structural steel with yield point (σ s) of 345MPa The following letters indicate the quality level, including A, B, C, D and E,ASTM A709 high strength steel.
