Product Description

EN 10216-5 Stainless Steel Tube - Cold Rolled Seamless Steel Tubes For Pressure Purposes

Material and Specification

EN 10216-5 is a European standard that specifies the technical delivery conditions for cold rolled seamless stainless steel tubes for pressure purposes. These tubes are intended for use in high pressure and high-temperature environments, and they offer excellent corrosion resistance and superior mechanical properties.

The standard covers various grades of stainless steel, including austenitic, ferritic, and duplex stainless steels. It outlines the requirements for dimensions, tolerances, surface conditions, and marking of the tubes.

Key Features

The EN 10216-5 stainless steel tubes designed for cold rolling and seamless production possess several key features that make them suitable for pressure purposes:

1. Corrosion Resistance: Stainless steel is known for its exceptional resistance to corrosion, making it ideal for applications in aggressive environments, such as the chemical and petrochemical industries.
2. High Strength: The cold rolled seamless manufacturing process enhances the strength and durability of the tubes, enabling them to withstand high pressure and temperature conditions.
3. Excellent Mechanical Properties: EN 10216-5 stainless steel tubes exhibit superior mechanical properties, including high tensile strength, good ductility, and impact resistance.
4. Versatility: The standard encompasses a wide range of steel grades, allowing for the selection of materials that best suit specific application requirements.

Chemical Composition 

The chemical composition of stainless steel in accordance with EN 10216-5 can vary depending on the specific grade. The table below presents the typical chemical composition range for the three main groups of stainless steels:
