A671 CB65 Carbon Alloy Welded Pipe
A671 CB65 Welded Pipe is manufactured using premium quality raw materials sourced from reliable and trustworthy vendors of the industry. These products undergo various heat treatments and testing procedures to verify that they comply with specified properties.
The main chemical components of A671 CB65 alloy welded pipe are carbon, manganese, silicon, chromium and small amounts of molybdenum, phosphorus and sulfur. Therefore, the low sulfur content of A671 CB65 straight seam steel pipe makes it easier to process into complex shapes, while corrosion-resistant elements such as chromium give pipe fusion welding very good corrosion resistance.
A671 CB65 straight seam welded steel pipe has a tensile strength of 450-585 MPa and a yield strength of 240 MPa. It can withstand high-pressure, high-load working environments such as boiler tubes, steam pipes, etc. and maintain stable performance.
