Abstract According to recent information from Qiangang Company's Technical Quality Department, after over a year of dedicated effort, the company has successfully developed high-carbon steel for saw blades in four grades: 30CrMo, 50Mn2V, 65Mn, and 75Cr. Among these, 65Mn and 75Cr have reached the stage of mass production and are now being supplied to key industry clients. This achievement marks a significant milestone in Qiangang’s technological development and market expansion.
Saw blade steel is widely used across various sectors such as mining, metallurgy, and construction. It demands high levels of purity, surface quality, dimensional accuracy, and processing performance. Currently, only a limited number of steel mills in China can meet the requirements of high-end users. According to the Technical Quality Department, the quality of saw blade steel heavily depends on advanced production equipment and technology, making it challenging to develop and produce. Especially for 75Cr steel, achieving high purity and precise composition control during the molten steel stage is critical. The continuous casting and hot rolling processes require strict control, reflecting the overall technical level of the steel mill.
At present, Baosteel, Angang, and Valin dominate the saw blade steel market. With the ongoing sluggishness in the steel sector, companies like Taigang and Tangshan have also entered this space. As a latecomer, Qiangang aims to quickly build its brand and gain a foothold in the market. To achieve this, the company has integrated its technical staff, sales team, and downstream customers to conduct detailed investigations into the demand for saw blade steel and the supply situation. From industry visits and analysis, it is clear that the demand for saw blade steel in China remains relatively stable, with an annual domestic market demand exceeding 100,000 tons. The top four saw blade manufacturers in the country consume around 80,000 tons annually, with two of them located in Tangshan City. This concentration not only facilitates production planning but also helps streamline product distribution. During customer interactions, technicians gained a deep understanding of product quality and delivery expectations, while also providing comprehensive insights into Qiangang’s equipment, process capabilities, R&D strength, and product quality, thereby strengthening customer confidence.
Supported by the Shougang Technology Research Institute and the sales department, the saw blade steel research team swiftly initiated industrial trials and mass production of 65Mn. By tracking customer usage, all performance metrics—including dimensions, surface finish, and mechanical properties—met the required standards. During customer visits, it became clear that 75Cr saw blade steel has a strong future demand and is considered the most technically challenging type. In April of last year, Qiangang began its first round of trial production for 75Cr saw blade steel. However, early challenges included cracks in the continuous casting billet and defects in the initial flat panels, which affected cutting performance. To resolve these issues, the technical team independently innovated, closely monitored each step of the production process, adjusted key parameters, and gradually solved problems related to slab cracking and heat treatment performance, ultimately meeting customer expectations. Additionally, due to the nature of saw blade manufacturers ordering raw materials monthly with small quantities and varied specifications, production scheduling becomes complicated and increases short-casting times. To address this, Qiangang adopted an active inventory strategy, merging orders from multiple customers with similar steel specifications to improve efficiency and reduce costs.
As of March, Qiangang has produced and sold 4,193 tons of saw blade steel. To further expand its product line, the company has completed trial production for 50Mn2V and 30CrMo. The technical team stated that their long-term goal is to create a "double high" premium product, continuously expand the range of specifications, and strive to reach the highest standards in plate shape, surface quality, and heat treatment performance. This ongoing effort reflects Qiangang’s commitment to innovation and quality, positioning itself as a reliable player in the competitive saw blade steel market.
