DIN2391 ST37.4 Seamless OD10 WT1.0 +A Cold Drawn Precision Steel Tube +/-0.03mm OD for Instrument Sensor Housing

DIN2391 ST37.4 OD10 WT1.0 Cold Drawn Precision Steel Tube +/-0.03mm OD

Product overview. This DIN2391 grade ST37.4 precision steel tube is cold drawn to a +/-0.03mm od and supplied in +A delivery condition. Wall thickness is controlled within +/-5 percent and straightness within 0.3 mm per meter, so the tube seats cleanly in instrument sensor housing assemblies without extra sizing, reaming or scrap loss on the line.

Tolerance control scheme

Key features

• Tight dimensional window on OD, wall and bore keeps fit and roundness repeatable batch to batch
• Soft annealed bright, produced on cold drawing lines with in-process laser gauging
• No cracking under flaring, flattening and cold bending tests
• Holding pressure without leakage after hydraulic proof test
• Ends cut square and deburred, plastic caps fitted on both ends

Typical application

Instrument Sensor Housing and similar assemblies that depend on stable bore and OD tolerance for sealing, guiding or fitting.
