Corrosion of steel reinforcement is the main cause of premature failure of concrete structures in the world today. Outokumpu is dedicated to providing you with the information on where to use Stainless Steel Rebar and how to choose the right designation as well as highlighting existing advice and standards.
Options for prevention or control of reinforcement corrosion where the concrete cover alone gives insufficient protection can be described in three categories; corrosion resistant reinforcement, corrosion inhibitors and impressed current cathodic protection (ICCP). The most straightforward, risk- and maintenance-free solution is to use Stainless Steel Reinforcement (SSR). Although SSR initially results in a higher cost than the normally used carbon steel, the long-term cost is often lower due reduced maintenance costs. Until recently, the only designations (grades) of SSR available to designers were the austenitic grades 304 and 316L or the highly alloyed 2205 duplex.
Use the left hand side navigation to discover why SSR is now the preferred technology for corrosion resistance in many countries and how Outokumpu's lean duplex designation LDX2101® is increasing the popularity of SSR.
