1. Good toughness. The impact value is similar to that of medium carbon steel and more than 10 times that of gray iron.
2. Strong corrosion resistance. Water spray corrosion test, 90 days of corrosion is only 1/40 of the steel pipe, is 1/10 of the gray iron pipe. The service life is 2 times that of gray iron pipe and 5 times that of ordinary steel pipe.
3. Good plasticity. Elongation ≥7%, similar to high carbon steel, while gray iron material elongation is zero.
4. High intensity. Tensile strength ob ≥420MPa, yield strength os ≥300MPa, the same as low carbon steel, is three times the gray iron material.
