Alumina Ceramics:
The export of Alumina Ceramic steel has grown rapidly. The imbalance between supply and demand in the domestic steel market stimulates corporate exports. From January to June, my country exported 30.69 million tons of steel products, an increase of 12.6% year-on-year; imported steel products were 6.83 million tons, a decrease of 1.8%, and imported steel billets and ingots were 320,000 tons, an increase of 50%. Converting billets into crude steel, the cumulative net export was 25.06 million tons, an increase of 17.3% year-on-year, accounting for 6.4% of my country's crude steel output. In terms of export prices, the average export price of bar and wire from January to June was US$624.3/ton, a year-on-year decrease of 18%; sheet metal was US$835.2/ton, a year-on-year decrease of 2.8%. Steel mills and social stocks run at high levels. The contradiction between market supply and demand spread to the circulation field, and domestic steel stocks continued to grow at the end of the previous year. On March 15, it reached a record high of 22.52 million tons, an increase of 3.51 million tons from the highest point of the previous year, of which 14.32 million tons of construction steel stocks accounted for 63.6% of the total inventory. After that, with the increase in seasonal consumption, the inventory gradually fell and fell to 15.4 million tons on July 26. The oversupply in the market also pushed up steel mill inventories. In mid-March, the steel inventory of key enterprises reached a historical record, reaching 14.51 million tons, a year-on-year increase of 29.7%. In late June, it fell to 12.68 million tons, still an increase of 29.9% over the beginning of 2012. Year-on-year growth of 11.4%.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
