Description

DIN 2391 ST37 Seamless Precision Steel Tubes Cold Drawn Seamless Carbon Steel Pipe

DIN 2391 ST37 Seamless Precision Steel Tubes Cold Drawn Seamless Carbon Steel Pipe

Material

DIN 2391 ST37 seamless precision steel tubes are manufactured from medium carbon steel (carbon steel) with excellent weldability, machinability, and strength. The material is cold drawn to achieve tighter tolerances and superior surface finish compared to hot finished pipes.

Specification

  • Standard: DIN 2391
  • Material Grade: ST37
  • Type: Seamless cold drawn precision steel tubes
  • Manufacturing Process: Hot finished seamless followed by cold drawing/pilgering
  • Dimensions: Outer diameter and wall thickness as per DIN 2391 standards, precise tolerances ensured
  • Surface finish: Smooth, precise with minimal machining allowances

Key Features

  • High dimensional accuracy and tight tolerances
  • Smooth surface finish without scale or rust
  • Excellent mechanical properties suitable for engineering applications
  • Good weldability and machinability
  • Available in various sizes and lengths according to DIN 2391 standards
  • Widely used in hydraulic cylinders, mechanical parts, automotive components, and construction
