LR AH40 shipbuilding steel plates Material Specification

If A 515 grade 70 pressure vessel plates thick in 50mm or under this thickness, LR AH40 shipbuilding steel plates, A515 Grade 70 plates are supplied in the as-rolled condition. Normalizing treatment can be ordered, but those greater than 2 inch (50 mm) in thickness must be delivered in normalizing state. A515 Gr 70plate and sheet are widely used in petroleum, chemical industry, power station, boiler and other industries. It is used to make reactor, heat exchanger, separator, spherical tank, paint tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum.

Main uses of LR AH40 shipbuilding steel plates, special steel. First, special steel is used for bearing manufacturing. Second, the special steel is used for mold manufacturing, which can withstand high temperature very well, and has excellent repeated use performance, which makes the mold quality excellent also. Third, the special steel is used in the manufacture of spring plates, and the chassis of some cars need to use the spring plate, which has good elasticity and flexibility. Fourth, the special steel is used in the aerospace industry. Fifth, the special steel is used to manufacture hardware products such as knives and drill bits.

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 LR AH40 shipbuilding steel plates 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 LR AH40 shipbuilding steel plates technical equipment.
