Effect of microalloying element crystallization on properties of S690QL+QT EN 10025-6 high strength steel

The company adopts the S690QL+QT EN 10025-6 high strength steel international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety S690QL+QT EN 10025-6 high strength steel management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

A299GrA steel plate is one of the materials widely used in boiler drums (steam drums) of coal-fired generator sets. Boiler plate S690QL+QT EN 10025-6 high strength steel is mainly used in the head and shell of subcritical boiler drum products. Generally used for various welding parts whose working temperature does not exceed 400°C, such as boiler steam drums, pressure vessels, etc., which require the steel to have a high medium temperature.

Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. S690QL+QT EN 10025-6 high strength steel, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of S690QL+QT EN 10025-6 high strength steel, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.

Laser cutting, it is a specific way of cutting S690QL+QT EN 10025-6 high strength steel 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 S690QL+QT EN 10025-6 high strength steel speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.
