Carpenter Technology Corporation, through its subsidiary Talley Metals Technology Inc., is now producing several grades of high-strength stainless steel rebar that have been used for concrete reinforcement in a wide range of construction projects where structures require long term resistance to the attack of chlorides from the concrete, road salt and harsh marine environments. The spiral ribbed stainless rebar has been used to resist corrosion in a variety of marine applications. It might also be considered for chemical plant infrastructure. Non-magnetic stainless rebar in the new product line can be considered for use in electric motor foundations, and in the construction of buildings housing MRI equipment. In addition, the same non-magnetic alloys are available as candidates for use in constructing âdepermingâ? piers, where the proper function of instrumentation is restored in docked vessels before they return to sea. The new line of stainless rebar has been offered as an alternative to materials such as carbon steel and products that are either coated or clad but, lacking adequate corrosion resistance in marine environments, have incurred excessive repair and replacement costs. The higher cost of stainless steel rebar, the company says, can be justified by its long design life and minimum maintenance requirements.
