Hot rolled EN steel grade S460QL material welding process

EN steel grade S460QL material,EN10028-2: 2003 P235GH steel refers to non-alloy and alloy steels with specific high temperature properties. With good plasticity, toughness, cold bending performance and welding performance, EN10028-2 P235GH steel plate and sheets are suitable for the manufacture of nuclear island steel containment, pressure vessels and equipment components. Our company can supply EN steel grade S460QL material, P235GH boiler plate thickness 8 to 150mm,EN steel grade S460QL material.EN steel grade S460QL material,Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the overall strength, competitiveness and anti risk ability of the company.Try to use high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.EN steel grade S460QL material,It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers. Our company has a dedicated after-sales service team and good after-sales service reputation, and has been recognized by customers over the past decades.
