BEBON STEEL - product - Steel for gas cylinders and gas vessels steel plate steel plate

Steel for gas cylinders and gas vessels steel plate steel plate

Also referred to as Atmospheric Corrosion Resistant Steel, this product is seen as an inexpensive and highly effective material to be used in structural applications which are exposed to the atmospheric elements.

The steel oxidises with pollutants in the air forming a thick layer of rust – this formation acts as a protective layer which prevents the steel from corroding. The layer constantly regenerates and forms over time.

Usage

These steel grades are characterised by a minimum yield strength of 245 - 355 MPa and by good weldability. The user of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material. The steel grades of this series are used for manufacturing gas cylinders by welding cold-formed parts together and normalizing the finished cylinder.
