Recently, Dezhou DRILLSTAR (Dezhou Drillstar Cutting Tool Co., Ltd., hereinafter referred to as “Dezhou Drillstar”), a company deeply engaged in deep hole machining and high-end cutting tool fields, officially launched a full range of Stellite Alloy products. With precise composition ratio, exquisite manufacturing technology and diverse product forms, the products have filled the gap in the company’s layout in the field of wear-resistant materials for extreme working conditions, further improved the product matrix of high-end cutting tools and wear-resistant components, and provided high-performance material solutions for key industries such as aerospace, petrochemical, energy and electric power, demonstrating the technical strength and innovative responsibility of national manufacturing enterprises.
Known as the “King of Hardness” in the industrial wear-resistant field, Stellite Alloy has been an indispensable core material under extreme working conditions since its birth, thanks to its excellent high-temperature resistance, corrosion resistance and high hardness. It is widely used in harsh scenarios such as high-temperature erosion, strong acid corrosion and high-stress wear. From aero-engine turbine blades to deep-sea oil drilling tools, and from chemical valve sealing surfaces to medical implant components, it can show excellent stability and durability. Relying on more than ten years of technical accumulation in cutting tool R&D and precision manufacturing, combined with its professional advantages in deep hole machining, Dezhou Drillstar accurately insight into the urgent demand for high-end wear-resistant materials in the industry. After many rounds of technical tackling and performance testing, it has successfully realized the independent R&D and large-scale production of Stellite Alloy series products, broken the technical barriers of high-end Stellite Alloy products, and promoted the localization upgrading of wear-resistant materials.
The Stellite Alloy products launched by Dezhou Drillstar this time cover four core categories: alloy powder, alloy ingot, coated electrode and flux-cored wire, including mainstream grades such as Stellite 1, Stellite 6/6B, Stellite 12 and Stellite 21. They can be accurately adapted to various processing technologies such as thermal spraying, 3D printing, oxyacetylene welding and laser cladding, meeting the personalized needs of different industries and scenarios. The products are processed by advanced technologies such as precision atomization and horizontal continuous casting using high-purity cobalt, chromium, tungsten and other core raw materials. They have uniform composition without segregation, extremely low impurity content, and their surface finish and dimensional accuracy are far higher than industry standards. Among them, the room temperature hardness of core products can reach HRC 55-65, and they can still maintain excellent hardness and toughness in high-temperature environment of 800℃. The chromium content is as high as 25-30%, which can form a dense Cr₂O₃ protective layer, effectively resisting the erosion of various corrosive media such as acid, alkali and seawater. The wear resistance is more than 30% higher than that of traditional alloy materials, which greatly extends the service life of terminal products and reduces the operation and maintenance costs of enterprises.
Relying on Dezhou Drillstar’s strong R&D strength and production system, the Stellite Alloy products launched this time have achieved multiple technological breakthroughs. The company has set up a professional R&D team, cooperating with well-known domestic professors in the cutting tool field, optimizing the alloy composition ratio and manufacturing process according to the characteristics of different industry working conditions, solving the industry pain points of traditional Stellite Alloy such as high processing difficulty, insufficient toughness and high cost, and realizing the perfect balance of three core performances: “wear resistance, corrosion resistance and high-temperature resistance”. In the production process, the company strictly follows the ISO quality control system, establishes a full-process standardized control mechanism from raw material procurement, production and processing to finished product inspection, and uses precision testing equipment to conduct comprehensive testing on core indicators such as hardness, composition, temperature resistance and corrosion resistance of products, ensuring that each batch of products meets international standards and customer needs, and has won wide recognition from customers at home and abroad with stable product quality.
Combining its core advantages in deep hole machining and cutting tool manufacturing, Dezhou Drillstar has deeply integrated Stellite Alloy with its existing products such as gun drills and BTA drills, launched a series of high-end cutting tools equipped with Stellite Alloy wear-resistant coating. Aiming at the deep hole machining needs in fields such as oil drilling tools, aerospace components and mold processing, it has created an integrated “material + cutting tool + process” solution, which effectively improves the wear resistance and service life of cutting tools under extreme working conditions. The processing efficiency is more than 30% higher than that of traditional cutting tools, helping customers achieve the development goals of quality improvement, efficiency increase, cost reduction and consumption reduction, further expanding the application boundary of Stellite Alloy, and also demonstrating the company’s core competitiveness of “integrated tool and machine, independent R&D”.
“The successful launch of Stellite Alloy is an important achievement of Dezhou Drillstar’s deep cultivation in the high-end manufacturing field and adherence to technological innovation, as well as a key step for the company to help the localization of wear-resistant materials and break the international technological monopoly,” said a relevant person in charge of Dezhou Drillstar. He added that in the future, the company will continue to focus on the technological iteration and product upgrading of Stellite Alloy, increase R&D investment, deepen its presence in key industries such as aerospace, petrochemical, energy and electric power, optimize product structure, expand application scenarios, and at the same time, rely on its own perfect service system to provide customers with one-stop services from material selection, process adaptation to after-sales support. It will continuously improve product competitiveness and market influence, empower the high-quality development of high-end manufacturing industry with professional strength, promote China’s wear-resistant material industry to a new height, and write a legend of innovation for national manufacturing enterprises.
It is reported that Dezhou Drillstar is located in Dezhou City, Shandong Province, a base for deep hole machine tool manufacturing. It is a high-tech enterprise specializing in the R&D, production and sales of gun drills, BTA drills and deep hole machining machine tools. It has an independent R&D team and a complete production and testing system. Its products are sold well at home and abroad, serving more than 100 customers. With precise, efficient and stable product quality and intimate services, it has established a good brand image in the industry. The launch of this series of Stellite Alloy products will further consolidate the company’s market position in the high-end manufacturing field and inject new momentum into its high-quality development.
