By Region: data shows that in the first quarter of Asia, crude steel RD 32 VSL vessel steel sheets production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year. According to the output ranking, according to the latest data of the RD 32 VSL vessel steel sheets world iron and Steel Association, the output of crude steel in the top ten countries in March 2020 was 126 million tons (85.71% of the world), and the output of crude steel in the first quarter was 376 million tons (85.07% of the world).
Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the RD 32 VSL vessel steel sheets project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of RD 32 VSL vessel steel sheets customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the RD 32 VSL vessel steel sheets steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
Spring steel has good fatigue strength and can be restored to its original state after repeated use, without deformation, because the spring has good ductility and can be changed back to the original state no matter how long it is stretched. RD 32 VSL vessel steel sheets, Spring steel has good elasticity. Spring steel can not only be made into springs, but also be processed into swords, which requires good elasticity. The tensile strength of spring steel is good, it will not break and can be recovered under the condition of tensile limit.
Service concept:Customer satisfaction is our value. Thank customers for their trust, respect their rights and interests, care about their needs, understand their concerns, realize their satisfaction and promote their success. Sincere and friendly, warm and thoughtful, relaxed and pleasant, considerate and tolerant. Attentive service, sincere care, professional excellence.
