In 2019, the output of pig iron in the world was 1.265 billion tons, with China accounting for 64%; the overseas output accounted for 36% (460 million tons), ranking 86.982 million tons of EU 28 countries, 74.907 million tons of Japan, 74.099 million tons of India, 73.264 million tons of CIS, and A283 grade C mild steel coil 47.521 million tons of South Korea. In the first quarter, the global output was 311 million tons, with a year-on-year decrease of 0.5%, with China A283 grade C mild steel coil increasing by 2.4%; the overseas output decreased by 5.4%, Among them, EU decreased by 9.2%, Japan increased by 1.3%, India decreased by 7.7%, CIS increased by 2.1%, and South Korea decreased by 4%.
In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.
45# steel is commonly used medium carbon quenched and tempered structural steel. The steel A283 grade C mild steel coil is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.
The company has our own truck fleet, and can transfer products flexibly and quickly. At the same time, we have large warehouses near the ports of Tianjin and Shanghai, so as to ensure that we can deliver high-quality products to customers in the first time. At the same time, it also greatly reduces the transportation cost, and realizes the double harvest of time benefit and economic benefit. Time guarantee is one of the important strengths of our service.
For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In A283 grade C mild steel coil, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.
It is a modern high-tech professional enterprise integrating scientific research, A283 grade C mild steel coil production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A283 grade C mild steel coil process technology development, technology transfer and related technical consulting and technical services.
