Nickel is one of the main raw materials for producing stainless steel and is irreplaceable. Currently, 30% of the nickel resources required by China's stainless steel industry rely on imports. The world is generally wary of China's stainless steel industry and adopts a blockade attitude towards technology and resources, making it difficult for nickel resources to enter China. Nickel resources have also become a bottleneck for the development of the stainless steel industry. Therefore, investment in upstream resources should be emphasized to ensure the supply of upstream raw materials, in order to connect the entire industrial chain and improve the profitability of enterprises.
