Recently, Zibo Qiangda Group Co., Ltd. has successfully developed and launched a new type of super corrosion-resistant high-strength bolt based on its technical accumulation in the field of fasteners for many years. This product aims to solve the problem of corrosion of fasteners in complex and harsh environments, and adopts an original surface treatment process and alloy formula to achieve a double breakthrough in strength and corrosion resistance.

This high-strength bolt uses special alloy materials. By optimizing the ratio of elements such as C, Cr, and Mo, its tensile strength reaches more than 1200MPa and its yield strength exceeds 1080MPa, which is 20% higher than traditional products. In terms of surface treatment, the group's patented multi-layer composite coating technology is used, combined with nano-level passivation film and anti-corrosion coating. After salt spray test, it has been rust-free for 1000 hours in a row, far exceeding the industry standard. The product is suitable for fields with extremely high requirements for corrosion resistance, such as marine engineering and petrochemicals, providing more reliable safety guarantees for the connection of key equipment.

The technical director of Zibo Qiangda Group said that the launch of the new super-corrosion-resistant high-strength bolts is an important achievement of the group's implementation of the "innovation-driven development" strategy. In the future, it will continue to deepen research and development to provide global customers with better fastener solutions.
