Product Description

DIN 2391 ST52 Hydraulic Steel Pipe has a carbon (C) content of 0.24%, a silicon (Si) content of 0.55%, and a manganese (Mn) content of 1.60%. In addition, it contains phosphorus (P) content of 0.045% and sulfur (S) content of 0.045%. It is worth noting that this kind of steel also contains trace amounts of alloying elements such as chromium (Cr) and nickel (Ni). The presence of these elements increases the strength and corrosion resistance of the steel.

ST52 Seamless steel pipe has excellent mechanical properties, including high strength, high toughness, and good welding performance. Specifically, its tensile strength is not less than 490MPa, the yield point is not less than 345MPa, and the elongation is not less than 22%. In addition, this kind of steel pipe also has good low-temperature toughness and can maintain excellent mechanical properties at lower temperatures.

Because st52 precision Seamless Carbon Steel Pipe has good mechanical properties and weldability, it is often used to manufacture various structural parts and mechanical parts. For example, bridges, ships, buildings, etc. are common application areas.
We can also supply Carbon Steel Pipe, APl Line Pipe, Galvanized Pipe in any form.

Production Process
①Main production processes of hot-rolled seamless steel pipes (△Main inspection processes):
Preparation and inspection of tube blank △ → heating of tube blank → perforation → pipe rolling → steel pipe reheating → diameter determination (reduction) → heat treatment △ → finished pipe straightening → finishing → inspection △ (non-destructive, physical and chemical, Taiwan inspection) → warehousing
②The main production processes of cold-rolled (drawn) seamless steel pipes:
Blank preparation→pickling and lubrication→cold rolling (drawing)→heat treatment→straightening→finishing→inspection
