Heat-resistant steel has good oxidation resistance, corrosion resistance and tissue stability. The thermal strength performance is high, and the process performance is good. Heat-resistant steel plates and sheets are commonly used in the manufacture of parts that work at high temperatures in industrial sectors such as boilers, steam turbines, power machinery, industrial furnaces, and aviation and petrochemical industries.

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 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 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.
