Literature Review of Commercially Available Alloys That Have Potential as Low-Cost Corrosion Resistant Concrete Reinforcement

A literature review was conducted with the goal of identifying alternative low-cost corrosion resistant steel reinforcement materials. The most promising alternate reinforcing materials seen to date that are less expensive than 300 series stainless steels include low-nickel austenitic stainless steels, and a variety of ferritic or martensitic 12-15 weight percent chromium steels. Steels with 2.5-10 weight percent chromium may also be of interest because they offer a marginal gain in corrosion performance at a very low cost. Several steel types that should undergo further evaluation are 201LN, 216, S41003, S24100 and S24000, HSS2, S41425, S41426, and S42300.
