Product Description

Motorcycle Front Fork DIN 2393 Carbon Steel Seamless Welded Pipe

 

Description:

 

Outside diameter : EN 10305-2 (DIN 2393)

Version : +C (BK) No heat treatment after cold drawning (for bending see NBK version)

The kind of tube is in confined restrictions to form it cold.

Straightness : Outside diameter > 15 mm = max 0,25% deviation of the length

Outside diameter 6 - 15 mm = straightened to the eye

Outside diameter < 6 mm = no guarantee for straightness

 

Lengths : Random 5-7 meters, cut on request

Straightness ≤0.5mm/1m
Roundness ≤0.5

OD range:15-200mm WT range: 0.8-16mm
OD tolerance:+/-0.06mm WT:(+/-0.03)
ID surface:≤0.4μm

 

Feature: High precision,Nice inner hole surface
