Title: Leading the Industry! Our Experts as Key Drafters Contribute to the Official Implementation of the New National Standard for High-Speed Tool Steel
Subtitle: Senior Engineers Zhipeng Chen and Elvis Chen Facilitate the Upgrade of National High-Speed Steel Standards, Highlighting Hanli's Industry Leadership
Release Date: SEP 1, 2025
Recently, the new national standard-GB/T 9943-2025 "High-Speed Tool Steel"-jointly issued by the State Administration for Market Regulation and the Standardization Administration of China, has been officially implemented. This standard serves as an authoritative technical document guiding the production, inspection, and application of high-speed tool steel in China. Its update holds significant importance for promoting quality improvement and technological advancement in China's high-end manufacturing sector.
It is particularly worth mentioning that our company's senior engineers, Zhipeng Chen and Elvis Chen, as key drafters, deeply participated in the formulation of this document. This not only represents high recognition of their professional expertise but also fully affirms our company's long-term technical accumulation, R&D capabilities, and industry contributions in the field of high-speed steel. It marks our company's firm position as a leader in domestic high-speed steel technology.
Technology Leadership, Defining New Industry Norms
The GB/T 9943-2025 standard replaces the previous GB/T 9943-2008 "High-Speed Tool Steel," GB/T 9941-2009 "High-Speed Tool Steel Plates," and GB/T 36708-2018 "Pre-Hardened High-Speed Tool Steel." The new standard adopts a grade designation method aligned with international norms and introduces more scientific and stringent requirements for key technical indicators such as chemical composition, mechanical properties, non-metallic inclusions, and macrostructure. It aims to comprehensively enhance the quality stability and consistency of high-speed steel products in China, meeting the demanding requirements of modern precision tools, high-end CNC cutting tools, aerospace, and other cutting-edge fields.
Wide Applicability and Strong Guidance
As clearly specified in the standard, it applies to:
Hot-rolled and forged high-speed steel bars (round steel, square steel, flat steel, etc.) with nominal dimensions not exceeding 350mm;
High-speed steel wire rods and wires;
Silver bright steel bars;
Cold-rolled steel plates with nominal thickness not exceeding 4mm and hot-rolled steel plates with nominal thickness not exceeding 15mm;
Pre-hardened high-speed steel bars with a nominal diameter of 1.0mm–15.0mm and surface finish as polished or cold-drawn.
At the same time, its chemical composition requirements also apply to steel ingots and billets. This clear delineation provides authoritative guidance for production, acceptance, and quality control across the entire industry chain.
Expert-Driven, Demonstrating Corporate Responsibility
Senior Engineers Zhipeng Chen and Elvis Chen stated, "We are deeply honored to participate in the formulation of the national standard and are fully aware of the significant responsibility it entails. We have integrated years of experience and data from production and R&D into the standard, hoping it will serve as a more precise 'ruler' to drive technological progress across the industry and contribute to the transformation of 'Made in China' into 'Precision Manufacturing in China.'"
Building on a New Starting Point, Creating the Future Together
Serving as a primary drafter of the national standard is an important milestone in Hanli Technology's development history. It proves that our company is not only a producer of products but also a leader and rule-maker in industry technological progress.
In the future, Hanli will continue to adhere to the philosophy of "technology first, quality foremost," strictly implement the new national standard, and take this opportunity to further increase R&D investment. We will launch more high-performance, high-quality high-speed steel products to create greater value for our customers and contribute Hanli's strength to China's journey from a "manufacturing powerhouse" to a "manufacturing innovator."
