To study the application performance of galvanized hot-formed steel, the usage performance of pure zinc-coated hot-formed steel is analyzed from aspects such as welding, bonding, coating, and hot stamping. Some of the usage performances are compared and analyzed with those of aluminum-silicon-coated hot-formed steel. The results show that the galvanized hot-formed steel has excellent spot welding, bonding and painting performance, which is comparable to that of the Al-Si coated hot-formed steel. Among them, the electrophoretic corrosion resistance of the pure zinc coating is significantly better than that of the Al-Si coating, which can better improve the anti-corrosion performance of the vehicle body. The hot stamping performance of the galvanized hot-formed steel is good, and no cracking occurs after forming, and the depth of the micro-cracks under the coating is less than 10 μm. Under the existing working conditions, the galvanized hot-formed steel can obtain good stamping, bonding, welding and painting performance.
