What is the a516 grade 70 flat bar smelt

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, a516 grade 70 flat bar 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 a516 grade 70 flat bar International leading steel materials supplier.

Flat steel is divided into galvanized flat steel, carbon flat steel, stainless steel flat steel, etc. according to the material. Flat steel can be divided into hot-rolled flat steel and forged flat steel according to the forging process. a516 grade 70 flat bar, Hot-rolled flat steel is a potential-rolled long steel with a rectangular cross-section for general use. Forged flat steel is a long steel plate with a rectangular cross section that is forged. Hot-rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery. The thickness of the flat steel is 8-50mm, the width is 150-625mm, and the length is 5-15m.

12Cr1MoVG high pressure boiler tube belongs to seamless steel tube. The manufacturing method of 12Cr1MoVG high pressure boiler tube is the same as that of seamless steel tube. High pressure boiler tubes are often in high temperature and high pressure conditions when they are used. Under the action of high temperature flue gas and steam, oxidation and corrosion will occur. a516 grade 70 flat bar, 12Cr1MoVG high pressure boiler tube is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good microstructure stability.

Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce a516 grade 70 flat bar, hot-rolled seamless steel tube by continuous rolling mill.

13CrMo4-5 seamless pipe is a kind of pressure resistant seamless pipe in accordance with the European standard EN 10216-2. The chemical composition of 13CrMo4-5 seamless pipe is C 0.10-0.17, Si ≤ 0.35, Mn 0.40-0.70, P ≤ 0.025, S ≤ 0.020, Cr 0.70-1.15, Ni ≤ 0.30, Mo 0.40-0.60, Al ≤ 0.04, Cu ≤ 0.03. Mechanical properties of 13CrMo4-5 seamless pipe: tensile strength: 440-590 MPa, yield strength: ≥ 290 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. a516 grade 70 flat bar, 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.
