The steel used for bridge beams should also have excellent welding function and low notch sensitivity, high strength, toughness, and load and impact from rolling stock, as well as outstanding fatigue resistance, certain low temperature resistance, and atmospheric corrosion resistance. Q460qC steel plate delivery status: a573-65 steel steel products are delivered in hot rolled, controlled rolled or normalized conditions.
The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel a573-65 steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the a573-65 steel market and has strong competitiveness.
Quenching Improve the hardness of a573-65 steel steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of a573-65 steel steel and comprehensive mechanical properties.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. a573-65 steel, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
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.
