High quality alloy steel tube cold rolled 4130 4135 4140 pipe 35mm 74mm

Precision steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure and no leakage, high precision, high finish, cold bending without deformation, flaring, flattening and no cracks, they are mainly used to produce pneumatic or hydraulic components, such as cylinders or The cylinder can be a seamless tube or a welded tube

The precision steel pipe has high dimensional accuracy and high precision, smooth inner and outer surface of the pipe. After heat treatment, there is no oxide film on the inner and outer surfaces of the steel pipe. deal with.

Mainly produce steel pipe grades: 10#, 20#, 35#, 45#, 40cr, 42crmo, 16mn, etc.

After negotiation, other grades of precision seamless steel pipes can also be supplied.

Basic use

Precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, seamless steel pipes for medium and low pressure boilers, etc., and can also be applied to steel sleeves, bearings, hydraulics, machining, etc. field!

Cold rolled steel is low-carbon steel rolled and finished at room temperature, below its recrystallization point. This permits better control over finished product shape, dimensions, and appearance. Characteristics are: Increased Strength. Tighter Tolerances.

Cold worked steels are typically harder and stronger than standard hot rolled steels. Cold rolled steel is essentially hot rolled steel that has been through further processing. Once hot rolled steel has cooled, it is then re-rolled at room temperature to achieve more exact dimensions and better surface qualities.

Because cold rolled steel sheet is prone to rusting, standard practice is to apply a rust-preventative oil at the exit end of the temper mill (the last processing step). Rust-preventative oils are different than forming lubricants in that they contain special corrosion-inhibiting additions.

product mode

The big gest advantage of alloy steel pipe can be 100% recycled, which is in line with the
national strategy of environmental protection, energy saving and resource saving. The national policy encourages the expansion of the application field of high pressure alloy pipe. At present, my country's consumption of alloy pipes accounts for only half of the total steel volume in developed countries. The expansion of the use of alloy pipes provides a broader space for industry development. According to the research of the expert group of the Alloy Pipe Branch of the China Special Steel Association, the demand for high-pressure alloy pipe long products in my country will increase by 10-12% annually in the future. Alloy pipe is defined by steel pipe according to the production material (that is, material), as the name suggests, is pipe made of alloy; while seamless pipe is defined by steel pipe according to the production process (seamless and seamless), the difference from seamless pipe is Seam pipes, including longitudinal welded pipes and spirals
