corrosion resistant super duplex steel pipe

Koudgetrokken ronde buizen van roestvrij staal ASTM A269 Hoogdrukbuizen van roestvrij staal

Cold drawn stainless steel round pipe is manufactured through a multi-stage drawing process that pulls a hot-rolled or extruded tube through a die at room temperature. This cold working process produces a pipe with superior dimensional accuracy, smoother surface finish, enhanced mechanical properties, and tighter wall thickness tolerances compared to hot finished alternatives. The cold drawing process work-hardens the material, increasing tensile and yield strength while
