Description

technical field

[0001] The invention belongs to the field of alloys, and in particular relates to a high-strength steel bar with high corrosion resistance and a preparation method thereof. Background technique

[0002] Generally, after 10-15 years of service in coastal and offshore areas, reinforced concrete structures generally suffer from severe corrosion damage, while in the salt lake area, they will show very serious corrosion damage after only 2-3 years of service. Among them, as the main structural material, the corrosion of steel bars is an important factor for the corrosion of reinforced concrete structures. The corrosion of steel bars not only greatly shortens the overall life of the building, but also poses a safety hazard. Therefore, the corrosion resistance of steel bars has become a hot issue in engineering circles at home and abroad.

[0003] The corrosion-resistant steel bars currently used mainly include coated steel bars, stainless steel bars and alloy cor...
