The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.
SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. A709 grade HPS50W bridge steel plate, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
Alloy steel means that alloy elements are specially added to improve the properties of steel. For example, nickel can improve the strength without reducing the toughness of steel; chromium can improve the hardness, corrosion resistance and wear resistance of high carbon steel. The properties of A709 grade HPS50W bridge steel plate, alloy steel depend not only on chemical composition, but also on proper heat treatment to a greater extent.
We supply more than 2,000 tons of high strength A709 grade HPS50W bridge steel plate low alloy steel coils to support the construction of Iraq's thermal power equipment projects. As a "Belt and Road" construction project, the Iraqi thermal power generation project has high requirements on the quality of steel for power generation equipment. In particular, the flue gas baffle door sealing system of A709 grade HPS50W bridge steel plate thermal power plants has extremely strict requirements on the composition, yield strength and tensile strength of steel. Our hot rolled low alloy steel coils have won the favor of customers for their excellent mechanical properties, standard sizes, and beautiful shapes.
The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality A709 grade HPS50W bridge steel plate products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.
On October 30, the Ministry of Ecology and Environment issued the "Action Plan for Comprehensive Control of Air Pollution in the Yangtze River Delta Region in the Fall and Winter of 2020-2021". The "Plan" stated that the steel production capacity of Tianjin will be controlled at 15 million tons by the end of December 2020. Around this time, Hebei’s steel production capacity will be controlled within 200 million tons, and the elimination of 4.3-meter coke ovens with longer furnace age and poor furnace conditions will be accelerated, and independent coking companies will gradually withdraw.
