The TELFORD Tempest Direct Unvented Domestic Cylinder, Stainless Steel, 200 litre capacity.

The properties of any stainless grade are defined not only by its alloy content but also by the way it is produced. Ustentic stainless steel 316L is often used in water tanks. This grade offers limited strength properties, so need to be thick enough to handle the internal pressure.

So, the ideal solution is a formable stainless steel that is strong enough to enable thinner structures - DUPLEX 2304. The Duplex Stainless Cylinder offers optimised composition alloy elements which have created a stronger and corrosion resistant product which out performs not only other stainless steels but other competing solutions too.
