After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, A131 DH40 oil platform steel plate tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of A131 DH40 oil platform steel plate steel and 542,000 tons of steel.
In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.
We have built solid cooperation with Myanmar Navy since 2015, starting from a try order about 412 tons LR AH36 shipbuilding steel plates. Myanmar navy builds frigate every year and book shipbuilding steel materials from us regularly. This time, the Myanmar navy’s local representative visit us and put another order about 2025 tons LR grade A steel plates. According to clients requirements, we arranged A131 DH40 oil platform steel plate SGS inspection for the LR grade A steel plates before shipping and send them inspection report.
Try to use A131 DH40 oil platform steel plate high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the A131 DH40 oil platform steel plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
Spring steel, as we can clearly know from its name, is one of the main materials used to make springs and special alloy steel for other elastic components. A131 DH40 oil platform steel plate, Spring steel has good comprehensive properties, it has heat resistance, low temperature resistance, oxidation resistance, corrosion resistance and so on advantages. Compared with alloy spring steel, carbon spring steel has less advantages, but its price is cheaper, and the source of raw materials is convenient. The disadvantage of carbon spring steel is that the elastic limit is low and it is easy to lose elasticity after repeated deformation.
Customer concept: customer first. Guided by market changes and guided by customer needs, we design the optimal product solutions and provide the best after-sales service. Partners: to reach a balance of interests with all stakeholders, to build a harmonious coexistence and win-win cooperation.
