This unique composition offers remarkable resistance to pitting, crevice corrosion, and stress-corrosion cracking, especially in harsh, chloride-rich environments. With a tensile strength ranging from 620 to 850 MPa and a yield strength of 450 to 550 MPa, they also boast good ductility. The ERW manufacturing process ensures strong, leak-proof seams and consistent mechanical properties throughout the pipe.
