S355J2WP seaport buildings used steel astm welding

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for S355J2WP seaport buildings used steel various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several S355J2WP seaport buildings used steel after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

EH500 steel plates and EH550 steel plates are both ultra-high-strength structural steel plates for ships and oceans. The addition of microalloying elements can not only improve the strength, compensate for the strength loss caused by the reduction of carbon equivalent, but also improve the welding performance, mechanical properties and process performance of the steel S355J2WP seaport buildings used steel. Due to the use environment requirements of EH500 steel plate and EH550 steel plate, it can meet the requirements of high strength, high toughness, high welding performance, and thickness direction performance.

The wear-resistant layer of S355J2WP seaport buildings used steel wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy S355J2WP seaport buildings used steel carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel S355J2WP seaport buildings used steel produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, S355J2WP seaport buildings used steel and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

With the development of China's market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes the group operation, intensive development and lean management, and through a rich series of products and project portfolio as well as a complete operation network, Build the company into a modern enterprise with scientific development concept, continuous innovation vitality, excellent corporate culture, strong sense of social responsibility and international first-class competitiveness.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
