Characteristics use, and application details of DIN2391 precision seamless steel pipe
DIN2391 precision seamless steel pipe is a steel pipe product with high precision, high finish, and excellent mechanical properties. The following is detailed information about DIN2391 precision seamless steel pipe:
First, the main characteristics of DIN2391 precision seamless steel pipe:
High precision and good finish.
After heat treatment, there is no oxide layer on the inner and outer walls of the steel pipe, and the inner wall is clean.
The steel pipe withstands high pressure, does not deform when cold bent, and has no cracks when expanded or flattened. It can be subjected to various complex deformations and mechanical processing.
The color of the steel pipe is light gray with white.
Second, the main uses of DIN2391 precision seamless steel pipe:
Mainly used in hydraulic systems, automobile manufacturing, and other industries.
Widely used in steel pipes for hydraulic systems, steel pipes for injection molding machines, steel pipes for hydraulic machines, steel pipes for ships, etc.
It is also suitable for EVA foaming hydraulic machinery, steel pipes for precision hydraulic cutting machines, shoemaking machinery, hydraulic equipment, high-pressure oil pipes, hydraulic oil pipes, ferrule joints, steel pipe joints, rubber machinery, etc.
Third, the size specifications of DIN2391 precision seamless steel pipes:
Outer diameter range: 16-325mm (some information mentions an outer diameter of 4-76mm, which may be a specific specification or application scenario).
Wall thickness range: 1-22mm (some information mentions a wall thickness of 0.5-6.0mm, which may also be a specific specification or application scenario).
Fourth, the material of DIN2391 precision seamless steel pipe:
Common materials include ST35, ST37.4, ST37, ST45, ST52, ST52.4, etc.
It also includes other materials such as E235, E255, E355, SAE1010, SAE1020, etc.
Fifth, the delivery status of DIN2391 precision seamless steel pipe:
The common delivery status is NBK (bright oxygen-free normalizing).
Sixth, the application fields of DIN2391 precision seamless steel pipe:
Hydraulic systems, automobile manufacturing, injection molding machine, hydraulic press, shipbuilding, EVA foaming hydraulic machinery, precision hydraulic cutting machine, shoemaking machinery, hydraulic equipment, high-pressure oil pipe, hydraulic oil pipe, ferrule joint, steel pipe joint, rubber machinery, forging machinery, die-casting machinery, engineering machinery, high-pressure steel pipe for concrete pump truck, sanitation vehicle, diesel engine, internal combustion engine, air compressor, construction machinery, agricultural and forestry machinery and other fields.
