Low carbon steel has been the conventional steel in use for the hotdip galvanizing technology. This steel is always accompanied by lean alloy chemistry that could enhance the adherence between the coatings and the steel surface. No report on the development of galvanneal steel using dual phase medium carbon low alloy steels as a source.
Corrosion Resistance of Zn-Al-Mg Alloys with Hypoeutectic Zn-Al-Mg alloys with hypoeutectic microstructure were melted through a high frequency induction furnace. The content of aluminum and magnesium in the alloys were between 1% to 2%. Scanning electron microscopy (SEM) was utilized to analyze microstructure and phase, respectively. Effect of alloying element contents on corrosion resistance was studied.
The alloyed high-grade steel DX52D (drawing quality) is deliverable with following hot-dip coatings:DX52D+Z (coating Zn), DX52D+ZF (coating Zn-Fe), DX52D+ZA (coating Zn-Al), DX52D+AZ (coating Al-Zn), DX52D+AS (coating Al-Si).
Effect of Heat Treatment on Formability of Hot-dip Hot dip galvanizing process is known as one of the tech-niques frequently used for protecting low carbon steels against corrosion. This procedure consists in applying a galvanized coating on steel surface by immersion in a molten Zn bath at about 450 al zn hot dip low carbon steels#176;C. The Zn protective coating structure consists of intermetallic FeZn compound layers,
Effect of Mg and Si on the Microstructure and Corrosion Behavior of ZnAl Hot Dip Coatings on Low Carbon Steel. Coatings formed on a low carbon steel by a two step hot dipping, primarily in a Zn bath and secondarily in a Zn6Al bath with or without 0.5 mass% Mg and 0.1 mass% Si addition. The effects of the Mg and Si addition on the

aluminium, aluminium-silicon alloy, Zn-5Al alloy and 55%Al-Zn alloy. Metals such as chromium and titanium cannot be applied to steel by hot dipping because of their high melting points (Townsend, 1993). Low-carbon steel sheets coated by hot dipping are available with a broad range of mechanical properties. Compared to
Study on the Corrosion Mechanism of Zn-5Al-0.5Mg-0.08Si A new type of hot-dip Zn-5Al-0.5Mg-0.08Si and Zn-5Al alloy coatings was performed on the cold rolled common steel. The hot-dip process was executed by self-made hot-dip galvanising simulator. SEM and EDS test results demonstrated that Mg was mainly distributed in crystal boundaries.
