EN10305-2 E355 Cold Drawn Electrolytic Zinc Welded Steel Tube Round Steel Tubing

EN10305-2 E355 WT0.5 Electrolytic Zinc Welded Steel Tube, Round Steel Tubing

Product Overview

With high dimension accuracy and fine surface quality, cold drawn precision steel tubing is ideal for hydraulic and pneumatic systems. Both seamless and welded cold drawn tubes are used for cylinders with smooth surfaces. BS EN 10305-2 grade E355 is specifically designed for precision applications and serves as an excellent material for barrels and cylinders.

Chemical Composition Comparison

Steel Grade	Steel Number	C max	Si max	Mn	P max	S max	Al min
E215	1.0212	0.10	0.05	0.70	0.025	0.025	0.025
E235	1.0308	0.17	0.35	1.20	0.025	0.025	-
E355	1.0580	0.22	0.55	1.60	0.025	0.025	-

Manufacturing Process

Produced by cold drawing over mandrel and die on ERW welded steel tube to achieve superior tolerance and excellent concentricity. Both outside and inside weld seams are completely removed during the cold drawing process.

Technical Specifications

Material: E355

Alternative Material: E235

Standard: EN10305-2

Technique: Cold Drawn

Outside Diameter: 6-80 mm

Wall Thickness: 0.5-10 mm

Delivery Conditions

+C: No heat treatment after final cold drawing process

+LC: Suitable drawing pass after final heat treatment

+SR: Stress relieve heat treatment in controlled atmosphere after final cold drawing

+A: Annealed in controlled atmosphere after final cold drawing

+N: Normalized in controlled atmosphere after final cold drawing operation

Key Advantages

Superior shape and form
Enhanced surface quality
Tight eccentricity and wall thickness tolerances
Excellent toughness at low temperatures
90% of cylinders in USA market use welded tubes
Cost-effective fixed lengths

Applications
