The weldability of A573 Grade 58, 65, 70 hot rolled plate is good. It means that under certain process and construction conditions, A573 Grade 58, 65, 70 hot rolled plate can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, A573 Grade 58, 65, 70 hot rolled plate etc. are common pressure vessel steel grades.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality A573 Grade 58, 65, 70 hot rolled plate products and more satisfactory services.
