ASTM A513 1010 1020 DOM Steel Tube

ASTM A513 1010 1020 DOM Steel Tube   Material   DOM (mandrel drawn) steel pipe is made from ERW (electric resistance welded) pipe, then cold-drawn over a mandrel to improve dimensional accuracy, concentricity, surface finish, and mechanical properties. 1008, 1010, and 1020 are low-carbon, plain carbon steels well-suited for forming, bending, and welding. 4130 is a chromium-molybdenum alloy steel with increased strength and toughness for more demanding applications.   Specification   Standard ASTM A513 Grades  1006 1008 1009 1010 1012 1015 1030 4030，etc. Manufacturing Process ERW → Cold Drawing Over Mandrel → Stress-Relieving Surface Finish Smooth, scale-free, weld flash removed Outer Diameter 6-350mm Wall Thickness 1-12.5mm Length Up to 12000 mm, customizable   Key Features   Excellent dimensional accuracy: Tight tolerances on OD, ID, and wall thickness. Enhanced mechanical properties: Higher yield strength and tensile strength compared to standard ERW. Excellent…
