A515 Gr 65 pressure vessel steel sheet size list data

Smelting process of A515 Gr 65 pressure vessel steel sheet, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.

The development A515 Gr 65 pressure vessel steel sheet of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with A515 Gr 65 pressure vessel steel sheet high-quality and efficient services, work together for win-win, and create a better tomorrow!

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of A515 Gr 65 pressure vessel steel sheet high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's A515 Gr 65 pressure vessel steel sheet technical equipment.

Hydrogen (H) is the most harmful element in general steel such as A515 Gr 65 pressure vessel steel sheet. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
