S690QL carbon steel plate sheet vs en 10025 2
The company has S690QL carbon steel plate sheet advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience S690QL carbon steel plate sheet, we have accumulated a large number of customers at home and abroad, and won unanimous praise.
Weathering steel is mainly used in railway, vehicles, bridges, towers and other steel structures exposed to the atmosphere for a long time. S690QL carbon steel plate sheet. Weathering steel is used to make structural parts such as containers, railway vehicles, oil derricks, seaport construction, oil production platform and containers containing hydrogen sulfide corrosion medium in chemical petroleum equipment. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, which benefits the weathering steel component manufacturers and users.
If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with S690QL carbon steel plate sheet, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.
S355J2 steel plate S690QL carbon steel plate sheet rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the S690QL carbon steel plate sheet single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
S690QL carbon steel plate sheet, A572 Grade 50 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the A572 Grade 50 steel coil thickness should not exceed 25 mm. For A572 Grade 50 steel, the C element content is 0.23%, the Si element content is 0.4% max, the Mn element content is 1.35% max, the P element content is 0.004% max, the S element content is 0.05% max, the V element content is 0.06%, the Ni element content is 0.015%, the Co element content is 0.05%.
