Marine steel plates are classified as medium-thick plates, hot-rolled steel plates used for manufacturing hull structures produced in accordance with the requirements of the classification society. First, the toughness of the marine steel ABS Grade A, GL-A hot-rolled steel strip, ABS EH36 plate is the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.
The company's GL-A hot-rolled steel strip steel products are sold all over the world with high quality and low price. We can process and cut all kinds of special-shaped parts according to your requirements, or we can set and roll futures of all kinds of material specifications according to your requirements, with fast delivery time. We sincerely welcome new and old customers from all walks of life to contact us for GL-A hot-rolled steel strip business negotiation. With the enthusiasm, good reputation and professionalism of our staff, we will provide excellent services to our valued customers in all aspects, so as to achieve common development and prosperity.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than GL-A hot-rolled steel strip. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel GL-A hot-rolled steel strip is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
After adding a small amount of niobium, vanadium and titanium to GL-A hot-rolled steel strip etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
