Why is hot rolled 09cuptire-a so cheap?

In mid-October, news from Shanxi called for the elimination of more than 20 million tons of coke oven capacity below 43 meters before the end of the year By the end of October, 123 million tons of production capacity had been eliminated, and in November, 1052 million tons were expected to be eliminated In the later period, localities will successively announce plans for reducing production capacity during the heating season this year, involving 2973 million tons of coking capacity16MnDR steel plate is suitable for low temperature pressure vessels manufacturing Grade 16Mn- indicates that the content of manganese (Mn) in the steel plate is relatively high, about 1% -16%, D- indicates low temperature, R- indicates pressure vessel (Normally, when the content of a certain chemical element in steel is high, it needs to be marked in the material, for example, 16% manganese is written as 16Mn; certain elements such as Cr and Mo are higher, written as Cr1, Mo1, Such as 12Cr2Mo1R) The normal delivery status is normalized delivery (Normalized),hot rolled 09CUPTIRE-A., 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system.
