Resumen

High Strength Stainless Steels (HSSS) are being developed with the aim to improve corrosion resistance of prestressed concrete structures in aggressive environments. In the present paper focus is given to mechanical and corrosion performance of a HSSS type 14301. The ability of passivation in alkaline media and the risk of local corrosion (pitting) in presence of chlorides, has been determined. Besides, the response of the stainless steel submitted to mechanical strains similar to those in service is considered with respect to the risk of corrosion, Stress Corrosion Cracking (SCC) and Hydrogen Embrittlement (HE). The cold-drawn HSSS 14301 shows higher tolerance to chloride ion than conventional prestressing steel. The local corrosion becomes significant for chloride contents above 0.75 M. The applied load moves pitting corrosion initiation at lower concentrations of chlorides. The pitting enhances risk for SCC developing, although the steel is more resistance to HE in comparison with conventional presstressing stee
