Grade 304 Stainless Steel is normally used in less corrosive environments and is adequate for most applications. Grade 316 has added Molybdenum enabling it to be used in more highly corrosive environments, for example, where this material may come into contact with seawater.
The system has a guaranteed yield stress of 94,200 psi. The thread is a cold rolled thread, similar to the standard Macalloy Pre-stressing bar. Standard lengths are 6m. Full strength couplers are available for longer lengths. The fully threaded bar has advantages over end threaded systems in that it can be cut to the precise length on site.
