In 2005, Gree Group first introduced the "SUN-Z-R" resistor cladding Gr.1 titanium plate overlap technology from Japan's Showa lead iron patent to China, marking the beginning of its cooperation journey with Nippon Steel.

During the cooperation period, both parties jointly participated in the entire process of 6MO stainless steel production technology, from rough to exquisite, and from single to wide application fields. Especially in the domestic application of the 6MO stainless steel NSSC 270 patented by Nippon Steel (a subsidiary of Nippon Steel), Gree Group has provided great support. At the critical moment when Nippon Steel's NSSC 270 product is transitioning to S31254 product, several trial orders and improvement suggestions from Gree Group are of great significance to Nippon Steel's stainless steel. Until now, S31254 remains one of Nippon Steel's flagship stainless steel products.

Recently, Mr. Zhang Qianli, the head of Nippon Steel's stainless steel business unit, visited Gree Group and brought the latest news: Nippon Steel will reorganize Nippon Steel's stainless steel to optimize production structure, improve operational efficiency, and enhance technological collaboration, in order to continuously consolidate its leading position in the global steel market. Based on the consideration of supply chain globalization, both parties expressed their views: Grey Group will comprehensively focus on the types and scope of supporting facilities, and strive to shorten the supply chain links and improve efficiency for end customers; Nippon Steel Stainless Steel has demonstrated the importance of stable quality in the supply chain through multiple customer return cases.

This meeting is not only a continuation of the cooperation journey, but also a profound reflection and exploration of the future development of the global supply chain. A stable and efficient supply chain, like blood, connects the world and provides an indispensable guarantee for the healthy development of global industries.
