Our company's en 10149-1 pdf power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the en 10149-1 pdf utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Bearing steel is a kind of steel used to manufacture rolling bearings such as balls and rollers, and even sleeves. It can also be used to manufacture precision measuring tools and coupling parts. The physical properties of its bearing steels are very good. Generally speaking, they are made by heat If rolled annealing and cold drawing annealing are used for delivery, the delivery status should be specified in the contract.

Alloy steel seamless pipe is a kind of high-quality seamless steel pipe with outstanding performance and characteristics. The alloy steel seamless pipe has excellent high-pressure resistance and can withstand greater pressure. Even under pressure, the en 10149-1 pdf, alloy steel seamless pipe is not easy to break, and it is more safe and reliable to use. It also reduces the loss of pipe material and reduces the maintenance work of pipeline.

Composition characteristics of low alloy structural steel, en 10149-1 pdf: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.
