Product Description

Tolerances to BS EN 10296-2 for Stainless Steel Tube Welding

Stainless Steel Tube Welding Introduction

Unlike the standards for flat and long products, the standards for stainless steel tube products contain information on tolerances. This is possibly because the tolerance requirements for tubes are simpler to define.

Stainless Steel Tube Welding Straightness

ODDeviation from straightness on tube length L
> 33.7 mm0.0020 L
< 33.7 mmAgreed at time of  enquiry and order


Example 50mm dia tube x 6000 mm long maximum deviation from straightness = 12 mm

A tighter tolerance of 0.0015 L can be agreed at time of order and enquiry.


EN 10296-2 2005 "Stainless Steel Tube Welding for mechanical and general engineering purposes - Technical delivery condition".

It covers a number of ferritic, austenitic, duplex austenitic-ferritic and heat-resisting steel. The mechanical properties are summarised in the table below.
