Introduction of a210-c low alloy seamless steel pipe

A210-c low alloy Steel Pipe produced by China steel pipe works is mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters and reheaters.

A210-c low alloy Steel Pipe produced by China steel pipe works is mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel, which is hot rolled (extruded, expanded) or cold rolled (drawn).


At present, the proportion of alloy steel pipe consumption in China's total steel is only half that of developed countries. The expansion of the application field of a210-c low alloy steel pipe provides a broader space for the development of the industry. According to the research of the expert group of alloy pipe branch of China Special Steel Association, the demand for high-pressure alloy pipe long materials in China will increase by 10-12% annually in the future. Alloy pipe is defined as steel pipe according to the production material (i.e. material). As the name suggests, it is a pipe made of alloy; Seamless pipe is defined according to the production process of steel pipe (seamless seam). What is different from seamless pipe is seamless pipe, including straight seam welded pipe and spiral pipe.


Chinese alloy seamless pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, a210-c low alloy steel pipe has lighter weight when its bending and torsional strength is the same. Alloy steel pipe is an economic section steel, which is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction.


Making ring parts with alloy steel pipe can improve the material utilization rate, simplify the manufacturing process, and save materials and processing hours, such as rolling bearing ring, jack sleeve, etc. at present, steel pipe has been widely used for manufacturing. A210-c low alloy steel pipe is also an indispensable material for all kinds of conventional weapons. The barrel and barrel should be made of steel pipe. Alloy steel pipe can be divided into round pipe and special-shaped pipe according to different cross-sectional area and shape. A210-c low alloy steel pipe is a kind of low alloy high strength structural steel.


Alloy steel pipe belongs to low alloy series - low alloy high strength structural steel (GB / t1591-1994).


In addition to a certain amount of silicon or manganese basic elements, it also contains other elements suitable for China's resource situation. Such as vanadium (V), niobium (NB), titanium (TI), aluminum (AL), molybdenum (MO), nitrogen (n), rare earth (RE) and other trace elements. According to the chemical composition and performance requirements, its brand is represented by q295a, B, Q345A, B, C, D, e, q390a, B, C, D, e, q420a, B, C, D, e, Q460C, D, e and other steel grades, which has the same meaning as carbon structural steel.
