The market price forecast of A588 Grade B weathering steel

ASTM A36 h beam is a common wide flange beam used in construction and machinery for its medium strength. Low carbon A588 Grade B weathering steel content makes it easy to be welded, machined as well as formed. Therefore, it is often employed by light applications where strength need is not so important.

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable A588 Grade B weathering steel 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 market and has strong competitiveness.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A588 Grade B weathering steel steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A588 Grade B weathering steel method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, A588 Grade B weathering steel, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
