EN10305-2 Standard ST52 Precision Steel Tube with Cold Drawn Technique for Mechanical Welded Steel Tube

ST52 EN10305-2 WT0.5 Precision Steel Tubes Mechanical Welded Steel Tube

Product Overview

Precision steel tubes, specifically mechanical welded steel tubes, are engineered for high strength and durability. They feature seamless construction that ensures uniformity and dimensional accuracy, essential for various applications. These tubes exhibit excellent resistance to corrosion and wear, making them suitable for demanding environments. Their precision manufacturing process allows for lightweight yet robust designs, ideal for automotive, construction, and industrial uses. With superior weld integrity and consistent performance, these tubes provide reliability and efficiency in mechanical systems, enhancing overall operational effectiveness.

Size Range	Outer Diameter: φ6-φ120 mm Wall Thickness: 0.5-15 mm
Application	High Precision Steel Tube is widely used in automotive parts, hydraulic systems, and high-precision machining

Production Process

Cold rolling by Cold pilger machine and Cold rolling machine

Delivery Conditions

+C: No heat treatment after the final cold drawing process
+LC: After the final heat treatment there is a suitable drawing pass
+SR: After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere
+A: After the final cold drawing process the tubes are annealed in a controlled atmosphere
+N: After the final cold drawing operation the tubes are normalized in a controlled atmosphere

Production Method

The cold drawn welded tube is produced by drawing ERW (electric resistance welded tube). During this process the sizing (wall thickness, inside and outside diameter), as well as weld integrity and surface finish is closely controlled to produce tube of the required size and mechanical property characteristics.

Key Advantages

Better shape and dimensional accuracy
Improved quality surface finish
Tight eccentricity and wall thickness tolerances
Enhanced tube safety
Good toughness at low temperatures
90% of cylinders in the USA market are produced with welded tubes
Cost-effective fixed lengths
