EN 10025-6 high strength steel S690QL+QT standard and specificaiton

EN 10025-6 high strength steel S690QL+QT, Pressure vessel steel plate is mainly used to make pressure vessels. But according to its temperature, corrosion resistance and other characteristics, the material of the pressure vessel steel plate used for pressure vessels is also different. The most common oil tanks in our lives, liquefied gas tanks are all made of pressure vessel steel plates. According to the purpose, the pressure vessel steel plate can generally be divided into: pressure vessel steel plate, low temperature pressure vessel steel plate and boiler pressure vessel steel plate, etc..

Our company has EN 10025-6 high strength steel S690QL+QT strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply EN 10025-6 high strength steel S690QL+QT deep processing service for products EN 10025-6 high strength steel S690QL+QT like cutting, drilling, bending, welding and grinding.

Quenching Improve the hardness of EN 10025-6 high strength steel S690QL+QT steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of EN 10025-6 high strength steel S690QL+QT steel and comprehensive mechanical properties.

The main function of boron in EN 10025-6 high strength steel S690QL+QT and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
