Alloy Steel Pipe
Generally, alloy steel pipe contains relatively more Cr while the ordinary carbon steel seamless pipe contains no or less alloy component, so this alloy pipe has more remarkable resistance to high temperature, low temperature and corrosion. In addition, it has more functions and higher value in use than common seamless pipe, thus finding wide applications in such industries as oil, aerospace, chemical, power, boiler, military, etc.
As an authorized steel and metal supplier, N-STEEL has cooperated with a lot of well renowned steel plants at home and abroad for a long time. The alloy steel pipe we supply comes with a wide external diameter range of 19mm-711mm, wall thickness of 1.65mm-50mm and length of 6m-11.8m. Sufficient supply of such industrial pipe is guaranteed.
