E195 Welded Cold Drawn Precision Steel Tube for Automotive Parts

Material Overview

E195 is a non-alloy quality steel grade (steel number 1.0034) commonly supplied as welded cold drawn precision tube under EN 10305-2. It is designed for applications where tight dimensional tolerances, consistent mechanical properties, and controlled surface quality are required—typical in automotive and general engineering components.

Specifications

• Product type: Welded cold drawn precision steel tube (typically circular; other cross-sections possible by agreement). (Source: hublebas.co.uk)

• Standard scope (EN 10305-2): Precision tubes with outside diameter D ≤ 150 mm. (Source: hublebas.co.uk)

• Delivery conditions (common options): +C, +LC, +SR, +A, +N (selected based on forming/machining needs). (Source: hublebas.co.uk)

• Surface quality: Smooth internal/external surfaces; Ra ≤ 4 μm per EN 10305-2 baseline requirement (with options for tighter roughness by agreement). (Source: hublebas.co.uk)

• Ends: Cut to length; deburring / internal weld bead control can be specified depending on the application. (Source: chewit.cn)

Key Features

• High dimensional accuracy for reliable fit-up in automated assembly and reduced secondary machining. (Source: hublebas.co.uk)

• Good formability (bending, expanding, swaging) when supplied in appropriate delivery condition (often +SR or +A). (Source: hublebas.co.uk)

• Stable performance for mechanical parts, balancing strength and ductility for automotive components. (Source: hublebas.co.uk)

• Welded + cold drawn process supports cost-effective precision tubing for high-volume production.

Our Advantages 

1. “Will the tube meet tight tolerances and surface finish to avoid rework?”
   We manufacture and inspect to EN 10305-2 precision requirements (tight tolerance focus and controlled roughness), helping reduce post-processing and improve assembly consistency. (Source: hublebas.co.uk)

2. “How do you ensure weld seam integrity for safety-critical parts?”
   Weld quality can be supported by non-destructive testing (NDT) methods widely used for tube integrity (e.g., eddy current / leak-tightness concepts). EN 10305-2 also references NDT standards for welded tubes where specified. (Source: hublebas.co.uk)

3. “Can you provide full traceability and inspection certificates?”
   We support documentation aligned with EN 10204 inspection documents (e.g., 3.1; 3.2 if contractually required) and structured inspection-document information practices (EN 10168), enabling batch/heat traceability for automotive audits.
