What are the precautions during the cutting of bs EN 10025-6-S690QL

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of bs EN 10025-6-S690QL circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and bs EN 10025-6-S690QL management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

bs EN 10025-6-S690QL plate weight:
1) Theoretical weight of bs EN 10025-6-S690QL plate:
The theoretical weight of a steel plate is the weight calculated based on the nominal size and density of the steel plate (previously called specific gravity). It is closely related to the length, size, and cross-sectional area of the steel plate.
2) The actual weight of bs EN 10025-6-S690QL plate:
The actual weight of the steel plate refers to the weight obtained through actual weighing, which is more accurate than the theoretical weight.

bs EN 10025-6-S690QL, Alloy plate is a steel plate with multiple uses because it has the following characteristics. First, better abrasion resistance. Alloy plate is more wear-resistant than ordinary steel plate. It does not scratch or wear, and has applications such as floor steel plate laying, steel plate wall and so on. Second, the alloy plate has higher strength. Third, the alloy plate is more resistant to high and low temperatures. Fourth, the alloy plate has outstanding corrosion resistance. As the steel laid on the ground, it must have good corrosion resistance. Because it will suffer from wind and rain for a long time, it must be very resistant, otherwise it will be damaged once it is corroded.

With the increase of temperature, the yield limit of bs EN 10025-6-S690QL will decrease monotonically, but the tensile strength of bs EN 10025-6-S690QL will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of bs EN 10025-6-S690QL. Near the blue brittleness temperature, the bs EN 10025-6-S690QL strength increases and the plasticity decreases. The elongation and section shrinkage of bs EN 10025-6-S690QL increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

bs EN 10025-6-S690QL, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, bs EN 10025-6-S690QL and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
