·Superior Fatigue Resistance: Cold-drawn welded (CDW) process enhances durability, minimizing wear in high-torque environments.
·Smooth Surface Finish: Clean, uniform surfaces reduce friction, boosting drive shaft performance and longevity.
·Global-Standard Sizes: Common sizes like Ø60 x 3.5 mm (2.362 x 0.138 inches) and Ø180 x 3 mm (7.087 x 0.118 inches), within Ø50–219 mm, meet automotive and industrial needs.
·Cost-Effective Reliability: High-quality carbon steels deliver top performance at competitive costs.

Manufacturing Process

Our EN 10305-2 precision welded drive shaft tubing is crafted for excellence:

1. Cold-Drawn Welded (CDW): Steel strips are welded and cold-drawn to achieve precise dimensions (e.g., Ø60 x 3.5 mm/2.362 x 0.138 inches), enhancing strength and surface quality for precision welded tubing.
2. Heat Treatment: Normalizing (+N) or cold-drawn (+C, +LC) conditions optimize mechanical properties for torque transmission.
3. Surface Finishing: Smooth, clean surfaces, often oiled or phosphated, ensure corrosion resistance and ease of assembly.
4. Quality Testing: Dimensional checks, tensile testing, and non-destructive testing (e.g., eddy current) ensure compliance with EN 10305-2 standards.
This process delivers high-strength welded tubing optimized for drive shaft applications.

Material Grades

Our drive shaft tubes are available in grades E355, E235, E420, and E275, each tailored for power transmission:

Chemical Composition Comparison (Max % unless specified)

Note: E420 may include alloying elements (e.g., Nb, V, Ti) up to 0.12% total.

Mechanical Properties Comparison (Cold-Drawn, +C)

Note: Properties are for cold-drawn (+C) condition, ideal for drive shafts. Other conditions (e.g., +N, +LC) vary in strength or ductility.

Delivery Conditions

·Cold-Drawn (+C): Maximum strength and precision, ideal for automotive drive shaft tubing (e.g., Ø60 x 3.5 mm).
·Cold-Drawn and Stress-Relieved (+LC): Enhanced formability for drive shaft components requiring further processing.
·Normalized (+N): Heat-treated for uniform properties, suitable for standard drive shafts.
·As-Welded (+W): Cost-effective option for less demanding drive shafts.

Grade Descriptions

·E235: Low-carbon steel with excellent weldability, ideal for cost-effective drive shafts in light vehicles.
·E275: Balanced strength and formability, perfect for medium-duty drive shafts in automotive applications.
·E355: Higher strength for demanding drive shafts in cars and trucks, offering superior fatigue resistance.
·E420: High-strength steel with enhanced toughness, ideal for heavy-duty drive shafts in industrial machinery.
