ASTM Mechanical Steel Tube Specifications

ASTM-A-519 (CDS or HFS) Covers carbon and alloy steel mechanical tube manufactured bythe 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 1018, 1026, 4130 and 4140 are the most common for distributor stock.
ASTM A-513 (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 H flEW. Type 2 covers As-Welded CREW. Both HREW and CREW usually are supplied in 1010 grade. Type 5 covers welded and drawn-over- mandrel (DOM) tube. DOM usually is supplied in1020 or 1026 grade.
ASTM-A-512 (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.
ASTM-A-106 (Mechanical) The applicable portions of this seamless carbon steel pipe specifications establish chemistry and property limits for large OD heavy wall mechanical tube sizes not covered by ASTM-A-519 specification.
