Changshu Changjiang Special Steel Co Ltd: China’s Premier Knife Steel Manufacturer
Changshu Changjiang Special Steel Co., Ltd (CSCJ) has spent over 40 years establishing itself as the cornerstone of China’s knifemaking steel industry. Founded in 1974, the company is now one of the largest and most respected manufacturers of cutlery-grade stainless steel in the world. Their steels are trusted by knife manufacturers globally for their consistency, performance, and metallurgical precision.
What sets CSCJ apart is that they are one of the few steel producers in the world large enough to support a dedicated cutlery steel department. This specialized division focuses exclusively on meeting the specific demands of the knife industry.
CSCJ‘S production capabilities include state-of-the-art equipment such as Electric Arc Furnaces, Argon Oxygen Decarburization, Electroslag Remelting (ESR), and intelligent heat treatment systems. Their comprehensive in-house processes allow them to produce high-purity steels like 440C, 8Cr14MoV, D2, and others that have become staples in both mass-market and premium knife production, as well as several new alloys that are currently being developed.
Now after decades of providing quality cutlery steel, CSCJ is moving to become the next big player in the super steel game. With millions of dollars spent on R&D, Ahonest has taken a step forward into powder metallurgy (PM) technology to produce PM-X Gold, a next-generation stainless super steel developed specifically for the knife and cutlery industry. PM-X Gold combines the corrosion resistance of high-end stainless steels with the toughness and edge retention of top-tier tool steels, making it a serious contender for high-performance knives in demanding environments.
With unmatched scale, and a commitment to innovation,
