BEBON STEEL - product - Simple pressure vessels steel steel plate

Simple pressure vessels steel 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.

Simple pressure vessels steel

Simple pressure vessels steel are characterised by a minimum yield strengTD of 235 - 275 MPa and by good weldability. TDe user of TDese steel grades must make sure TDat his calculation, design and processing meTDods are appropriate for TDe material.
