20Cr hot rolled alloy steel tensile test

The factory is located in the central China, with convenient transportation and abundant resources. The main products are various construction steel plates, steel pipes, steel sections, and steel structure processing parts. Used in the 20Cr hot rolled alloy steel manufacture of railway tracks, pressure vessels, boilers, hulls, bridges, various types of steel, etc. With an annual output of 2.23 million tons of steel plates, 2.04 million tons of steel pipes and 1.54 million tons of section steel in 2002, it is an important pig iron base in Henan Province.

The 20Cr hot rolled alloy steel steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the 20Cr hot rolled alloy steel internal quality of the steel.

In the era of digital economy, the unleashed development stages of digital and intelligent transformation of steel enterprises are standardization, informatization, lean, digitization, networking, intelligence, and intelligence. The Internetization of steel trade has become an important direction for the transformation of about 30% of enterprises. Only five large steel companies have adopted the development of the big data industry as one of their development strategies. Only China's BBNsteel has included intelligent manufacturing in the company's 13th Five-Year Plan.
