[Molybdenum Express] SMM July 16: Recently, several stainless steel enterprises in China have started mass production of products such as the low-molybdenum duplex stainless steel S32304. In terms of cost, compared with 316L and 2205, S32304 significantly reduces the usage of molybdenum and nickel alloys, meeting the demand for reducing molybdenum content and lowering costs under current high raw material prices. By relying on a high-chromium and high-nitrogen composition, it achieves chloride corrosion resistance equivalent to that of 316L, and its yield strength is nearly twice that of ordinary austenitic stainless steel, enabling thinner and lighter equipment sheets and plates and reducing total material usage. Additionally, it offers excellent resistance to stress corrosion and fatigue, along with stable welding performance, making it suitable for end-use industries such as water treatment, municipal environmental protection, and general chemical equipment.
