If Type S or Type E is required for close coiling or cold bending, Grade A is the preferred grade; however, this is not intended to prohibit the cold bending of Grade B pipe. Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer. 4. Materials and Manufacture of ASTM A53 Pipes
Qualification test of welders — Fusion welding — Part 1: Steels. Withdrawn and replaced by EN ISO 9606-1 [b] [9] EN 1090-1: Execution of steel structures and aluminium structures - Part 1: Requirements for conformity assessment of structural components EN 1090-2
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications. The number is in the following format: x.yyzz(zz)
ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is the most commonly specified ASTM standard in the US for hollow structural sections. Another related standard is ASTM A501, which is a hot-formed version of this A500.
