Stainless steel fiber is a high-tech, high value-added intensive project that has gradually shifted from developed countries to developing countries. Stainless steel fiber products have high strength, no deformation, good stability, and strong corrosion resistance. They are widely used in aviation, petroleum, and precision instrument manufacturing, and are ideal reinforcement materials for polymer organic polyester products. In terms of price, the price of 0.04mm is 200000 yuan/ton, making it a cost-effective variety.
