Products Description
DIN2391 ST52 Seamless Carbon Steel Pipe
Why Choose DIN2391 ST52 Seamless Carbon Steel Pipe?
- ST52 is a high-strength, low-alloy steel with a minimum yielding strength of 355 MPa. For emergencies with high demand for mechanical strength and resistance to change in evacuation, examples include equipment frames, liquid pump systems, and heavy-duty construction equipment.
- ST52 has outstanding machinability, easy machining, drilling, car cutting, metal cutting, emergency fitting, liquid punching, cylinder forming, machine parts, etc., precision zero parts.
- In the production process, the light on the inside of the channel is not clear, the light is not available, and the liquid is reduced to the maximum extent.
Applications of DIN2391 ST52 Seamless Carbon Steel Pipe
- Hydraulic and pneumatic cylinders: cylinder barrels
- Automotive engineering: drive shafts, axles, and suspension systems
- Construction and heavy machinery: load-bearing structures, booms, and frames
- Mechanical and structural engineering: precision equipment, fixtures, and assemblies
- Agricultural equipment: cylinders, rollers, and frame components

Possible Alternative Grades
- SAE 1026 (ASTM A513 Type 5) – U.S. equivalent used in DOM tubing; similar mechanical properties
- ASTM A519 1026 – Seamless mechanical tubing for pressure and strength applications
- EN 10305-1 E355 – European precision steel equivalent with tighter tolerances
- ASTM A106 Grade B – For pressure pipe applications but lower in mechanical strength
- ST44 or ST37 (DIN 2391) – For lighter-duty applications with lower strength requirements
Packaging
Once the pipes have passed all inspections and tests, they are ready for packaging. They are usually packaged in bales wrapped in plastic. The pipes can be bundled and ready for delivery according to customer requirements, ensuring that the pipes are protected during transportation and prevent surface damage.
