Standards and features:
1. high strength. Tensile strength σs≥420MPa, yield strength σs≥300MPa, same as low carbon steel, three times that of gray iron
2. Good toughness. The impact value is similar to that of medium
carbon steel, which is more than 10 times that of gray iron
material.
3. Good plasticity. The elongation is as large as 7%, which is
similar to high carbon steel, while the gray iron steel has an
elongation of zero.
4. Strong corrosion resistance. In the water spray corrosion test,
the corrosion amount in 90 days is only one tenth of that of the
steel pipe, which is one tenth of that of the gray iron pipe. The
service life is twice that of gray cast iron, which is 5 times that
of ordinary steel pipe.
