According to the data released by the Japan iron and Steel Union (JISF), the export volume of Japanese steel in the second quarter of 2020 ship construction RE 36 hull steel plate is about 4.959 million tons, a year-on-year decrease of 14.2%; the export volume in the first half of 2020 is about 11.07 million tons, with a year-on-year growth of 1.8%. It has been revealed that the year-on-year increase in export volume does not mean that Japan's export ship construction RE 36 hull steel plate situation of Pugang is better in the first half of the year, but only because the base number of the same period last year is too low.
Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of ship construction RE 36 hull steel plate service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of ship construction RE 36 hull steel plate products.
Laser cutting, it is a specific way of cutting ship construction RE 36 hull steel plate steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting ship construction RE 36 hull steel plate speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.
The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The ship construction RE 36 hull steel plate, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.
