Export thickness of steel nm450 steel material

Standing at a new historical starting point, we adapt to the requirements of supply side thickness of steel NM450 structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading thickness of steel NM450 steel materials supplier.

Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between thickness of steel NM450, hot rolled sheet and cold rolled sheet?

According to the latest data released by the world iron and Steel Association, in March 2020, the crude steel production of 64 countries and regions included in the statistics of the organization totaled 147 million tons, down 6.4% year-on-year. In the first quarter, the thickness of steel NM450, global crude steel production reached 442 million tons, down 1.3% year-on-year. Because of the new crown epidemic, factories in Europe, the United States and other places were shut down, Global steel production outside China fell the most since the financial crisis.

When pouring the wear-resistant steel plate with high Mn content, the content of manganese oxide in the mold powder will increase during the pouring process. The higher the Mn content in wear-resistant steel plate, thickness of steel NM450, the more manganese oxide content in the mold powder. The higher the content of manganese oxide, the lower the viscosity of mold flux, which deviates from the initial viscosity of slag and gets the ideal value.
