JIS SM490YB plates for boiler applications
The company adopts the 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 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.
Boiler steel plate mainly refers to the hot-rolled medium and heavy plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The main boiler steel materials are high-quality structural steel and low-alloy heat-resistant steel. Common boiler steel includes low-carbon killed steel smelted in open furnace or low-carbon steel smelted in electric furnace, with carbon content WC in the range of 0.16% - 0.26%.
Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified. In the case of personalization, our logistics service also provides personalized service projects.
JIS SM490YB plates,X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.
JIS SM490YB plates,Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel.
The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
JIS SM490YB plates,On March 26, 2020, the Mexican Ministry of Economic Affairs issued an announcement in the official gazette that the fourth anti-dumping sunset review investigation was initiated on hot rolled steel plates originating in Russia and Ukraine and boron-containing hot rolled steel plates originating in Russia. The TIGIE tax numbers of the steel products involved are 7208.10.99, 7208.26.01, 7208.27.01, 7208.38.01, 7208.39.01, 7225.30.04, 7225.30.05, 7225.40.03 and 7225.40.04.
