EN 10120 P265NB is a mature steel used for medium to low-pressure welded gas cylinders.

P265NB steel plates and strips offer excellent weldability, cold forming properties, and toughness, making them primarily suitable for manufacturing welded gas cylinders that withstand certain pressures, such as compressed air cylinders, carbon dioxide cylinders, and inert gas cylinders.

It holds a significant position in the global gas cylinder manufacturing industry.

When selecting this material, it is essential to strictly adhere to standard requirements and optimize processes and quality control based on specific application scenarios.

Carbon Equivalent of P310NB Steel Sheet and Strip for Welded Gas Cylinders: CEV ≤ 0.4% (Thickness ≤ 30 mm)

Carbon equivalent (CEV) is calculated using the International Institute of Welding (IIW) formula:

CEV = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15

P265NB steel plate and strip is primarily used for manufacturing medium-low pressure welded gas cylinders, with common application scenarios including:

1. Industrial welding gas cylinders: such as compressed air cylinders, carbon dioxide cylinders, argon cylinders, nitrogen cylinders, etc.

2. Automotive welding gas cylinders: such as hydrogen cylinders for new energy vehicles (medium-low pressure grade), LNG cylinder shells, etc.

3. Other pressure vessels: small welded pressure vessels, cylinder accessories (such as neck rings, bases), etc.

International Equivalent Materials

* Equivalent materials are only approximations, mechanical properties and chemical composition must be compared during application design.
