A 512 Cold-Drawn Buttweld Carbon Steel Mechanical Tubing (CDBW). Covers carbon steel mechanical tube manufactured from hot strip by the hot continuous weld process and subsequently cold drawn. Standard grades for CDBW are 1010, 1012 or 1020 depending upon various factors.
A 513 Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing (ERW-DOM). Covers carbon and alloy steel mechanical tube manufactured by cold forming and electric resistance welding of hot rolled or cold rolled strip. Type 1 covers As-Welded HREW, Type 2 covers As-Welded CREW Roth HREW and CREW usually are supplied in 1010 grade. Type 5 covers welded and drawn-over-mandrel (DOM) tube. DOM usually is supplied in 1020 or 1026 grade.
A 519 Seamless Steel Mechanical Tubing (CDS or HFS). Covers carbon and alloy steel mechanical tube manufactured by the seamless process (extruded or pierced) followed by hot finishing or cold finishing. Chemistry and dimensional tolerances are the controlling factors. Supplemental requirements are available on special order basis. Although many grades are listed, grades 1016, 1026, 4130 and 4140 are the most common for distributor stock.
A 106 Seamless Carbon Steel Mechanical Tubing (HFS). The applicable portions of this seamless carbon steel pipe specification establish chemistry and property limits for large OD heavy wall mechanical tube sizes not covered by ASTM-A-519 specification.
