Product Benefits:
1.No inherent scrap value thus reducing risk of theft.
2.Moderate weight and easy installation.
3.Can be used in -30℃ to 70 ℃degrees environment.
4.30 years of service life.
5.Tested by national security agencies. Compressive, bending and impact resistant. Heat, cold, acid, etc.
6.Corrosion resistance, meet the needs of environmental protection, and reduce the exploitation of mining resources; beautify the city, classify the coloring, and enhance the taste of the city.
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.
