According to the data released by the Japan iron and Steel Union (JISF), the export volume of Japanese steel in the second quarter of 2020 20Cr hot rolled alloy steel is about 4.959 million tons, a year-on-year decrease of 14.2%; the export volume in the first half of 2020 is about 11.07 million tons, with a year-on-year growth of 1.8%. It has been revealed that the year-on-year increase in export volume does not mean that Japan's export 20Cr hot rolled alloy steel situation of Pugang is better in the first half of the year, but only because the base number of the same period last year is too low.

Advantages of 20Cr hot rolled alloy steel, ordinary carbon killed steel plate: there is no gas in the steel plate, the impurity is relatively small, the stress is very uniform, and it has good welding performance. It is widely used in parts with high requirements. Disadvantages of ordinary carbon killed steel plate: the surface quality of the killed steel plate is not as good as that of boiling plates, there are concentrated shrinkage holes, and the killed steel plate price is more expensive.

Box making, door-to-door: fill in the packing plan: box making time, ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, door point, contact person, telephone number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date). Internal loading: fill in the packing plan: ship name, voyage number, customs declaration number, transfer port, destination port, gross weight, number of pieces, volume, cabin number, etc., and arrange the train shift 1-2 days before the closing date (two days before the ship's date).

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. 20Cr hot rolled alloy steel Heat treatment process refers to the ability to change the microstructure and properties of 20Cr hot rolled alloy steel after heat treatment, including hardenability, hardenability, temper brittleness, etc.
