Iron-based shape-memory alloy
Shape memory alloys (SMA) return to their original shape after a pre-elongation through heat supply. memory®-steel remembers the original shape due to the «martensite to austenite» crystal structure transformation.
memory®-steel is iron-based and is suitable for construction use.
Uniform prestressing without friction loss.
The existing internal reinforcement is relieved due to prestressing and hence the service-life of the structure is extended.
