sa573 gr.70 structural steel plate product upgrade structure adjustment

According to the separate performance report released by India's Jindal stainless steel (Sisal) Co., Ltd. (JSHL), as of March 31, 2020, due to the global economic slowdown, epidemic situation, imports and other factors, its sa573 gr.70 structural steel plate stainless steel sales decreased by about 10% to 600000 tons from 667000 tons in the previous fiscal year, and its net sales decreased by nearly 7% to 83.396.9 billion rupees, with the same gross operating profit (EBITDA) After tax profit increased by 22.4% to 3.203 billion rupees. The adoption of the new tax system has a positive impact of RS 220 million on after tax profits.

C45 steel heat treatment: Quenching has low hardenability, and it is easy to cause uneven hardness of the drill rod during heat treatment, resulting in deformation or even cracking. The hardness after quenching is about 42 degrees, which is much lower than the 55 degrees of 42CrMo brazing rod. Therefore, the wear resistance is extremely poor. Due to its low price, the sa573 gr.70 structural steel plate materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.

Management information and high efficiency. Because of the rapid flow of sa573 gr.70 structural steel plate goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation

The main challenges facing the current low-carbon development of the steel industry are as follows: First, insufficient energy resource endowments, coal and coke account for nearly 90% of energy input. Second, the crude steel output is relatively large, accounting for more than half of the global output. Third, there are a large number of enterprises, with more than 500 enterprises with smelting capabilities, and their structure and level are quite different. Fourth, the carbon emission mechanism is complex, involving multiple carbon emission mechanisms such as energy combustion emissions, indirect emissions corresponding to electricity and heat consumption.
