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. The better solution is a formable stainless steel that is strong enough to enable thinner structures. Telford Tempest Unvented Stainless Steel Cylinder are made from DUPLEX 2304 Stainless Steel that 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.
