Great Group is a comprehensive enterprise mainly engaged in spot warehousing, shear processing, sales and distribution of special alloys. After 20 years of hard work, we have finally become a large special alloy material supply group in Asia Pacific and even the world. We have stored over 10000 tons of titanium and titanium alloys, nickel and nickel based alloys, dual phase steel, super stainless steel, and various supporting welding materials in our Tianjin factory and three major bonded warehouses. This has built a solid and smooth bridge of dialogue and cooperation between special steel giants in the United States, Europe, Japan, and more than 3000 domestic industries. As a professional enterprise engaged in the special steel business, Great Group has a mature processing and supporting service center, which transports a large amount of special steel to the market every year. After all, special steel is a relatively niche and high-end metal, and many users are not familiar with its performance and application, which inevitably leads to a "detour" in the use process. In the face of this common demand, we will share the technical data we have summarized for many years through this official account, including material introduction, feature summary, application cases, etc. We hope that through this technical communication mechanism, we can provide more users with detailed questions and answers.
