EN 10025 S690QL high strength steel equivalent din material

ASTM A514 steel plate is a high yield strength, quenched and tempered alloy steel plate suitable for welding. A514 steel plate has high strength, and EN 10025 S690QL high strength steel it can maintain mechanical properties even at very low temperature. At the same time, A514 steel plate also has good fatigue resistance, high toughness and low brittleness transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance.

Compared with the common pressure vessel, the pressure parts of the boiler not only bear the pressure, but also suffer from the radiation and erosion of the high temperature flue gas. Once the pressure components of the boiler fail in operation, it will cause extremely serious consequences. Therefore, the EN 10025 S690QL high strength steel, steel materials used to manufacture the pressure components of the boiler must have enough high strength, plasticity, toughness, fatigue resistance and corrosion resistance, as well as good high-temperature mechanical properties for high-temperature components.

Cold rolled EN 10025 S690QL high strength steel steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner EN 10025 S690QL high strength steel steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
