Effect of Heat Treatment Conditions on Corrosion Resistance of 0.28C–1.4Mn–0.3Si–0.26Cr Steel with Nb, Ti, and V Microadditions

Abstract

The article presents the results of the research on the influence of heat treatment conditions on corrosion resistance of newly developed HSLA-type (High Strength Low Alloy) steel in selected corrosive environments. Laboratory tests were carried out with using a salt spray chamber, enabling the continuous spraying of brine mist (5% NaCl) during 96 h under high humidity conditions. Additionally, as part of corrosion experiments, tests were carried out using the gravimetric method, in which the intensity of corrosive processes was measured by the linear corrosion rate. The research conducted revealed that the best corrosion resistance was noted for steel with a high-temperature tempered martensite microstructure. Investigated 0.28C–1.4Mn–0.3Si–0.26Cr steel with Nb, Ti, and V microadditions can be used in offshore drilling constructions and production platforms exposed to salts present in sea water, chlorides, sulfates, carbonates, and bromides, among others.

The Influence of Heat Treatments in Corrosion Resistance of Austenitic Steels

“…Stainless steels are generally used in aggressive environments due to their passivation capacity [7,10,13,14,15].…”

“…In the paper [ 8 ], interesting studies on the modification of Zn-based protective coatings by tungsten trioxide (WO 3 ) nanoparticles were presented. The effect of heat treatment on the corrosion resistance of newly developed HSLA-type steel 0.28C-1.40Mn-0.3Si-0.26Cr with micro-additions of Nb, Ti, and V was discussed in the article [ 9 ].…”
