We have a firsthand perception of the market demands, listen attentively to the feedback from heat exchanger manufacturers, analyze and summarize the changes in technology. We have introduced various categories of special materials, ranging from Japanese titanium plates to super austenitic stainless steels like S31254 and 904L, and then to Hastelloy C-276. Each technological iteration stems from our precise capture of "unmet demands". In this process, the more complex the corrosive environment is, the more necessary it is to break away from the mindset of using conventional materials, which has also led to the birth of our "differentiated" business philosophy. The Gre Group has successively introduced scarce in-stock materials such as Hastelloy C-2000, BC-1, and Alloy 59, etc., to address the "anxiety about special materials" of end-users in special working conditions, such as their fruitless search for the materials, exorbitantly high prices, and slow delivery times. On this basis, the Gre Group implements the policy of "accepting orders starting from one piece + rapid delivery within 72 hours", breaking the industry dilemmas of "special working conditions equal to an extremely long cycle" and "small batches equal to high costs".

1. Alloy C2000 possesses excellent corrosion resistance, especially showing good resistance to some complex environments containing multiple corrosive media. 2. Alloy BC-1 is a kind of nickel-based alloy, which features high strength, good toughness, and outstanding resistance to high-temperature oxidation. It is often used in working conditions with high temperature, high pressure, and a certain degree of corrosiveness. 3. Alloy 59 generally refers to the nickel-chromium-molybdenum alloy, which has remarkable corrosion resistance and oxidation resistance.
