The copper brittleness defects control of RA hull construction steel

The use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight. It must be noted that for components that may be bent, the allowable stress must be corrected to ensure the robustness of the structure. Sometimes low-alloy high-strength steel is used to replace RA hull construction steel, carbon structural steel without changing the cross-sectional size. Its sole purpose is to obtain a stronger and more durable structure without increasing weight.

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of RA hull construction steel circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and RA hull construction steel management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by RA hull construction steel metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the RA hull construction steel steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

Our strutural steel plates are not attacked easily by the chemicals in harsh weather. They are a hard, strong, and durable product. Their characteristics are tested through tests. We perform hardness, pmi, micro, chemical, mechanical, macro, ultrasonic test and more. We pack carbon steel plates, RA hull construction steel, hot rolled plates, structural steel sheets safely to maintain their good performance so that they serve longer than usual.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
