Description

2007 SECTION II, PART ASA-414/SA-414M SPECIFICATION FOR STEEL, SHEET, CARBON, FOR PRESSURE VESSELS SA-414/SA-414M (Identical with ASTM Specification A 414/A 414M-01, except for the deletion of Note A under para. 1.3 and the addition of para. 6.2 on thickness tolerances.) 1. Scope 1.1 This specification covers hot-rolled carbon steel sheet for pressure vessels involving fusion welding or brazing. Welding and brazing technique is of fundamental importance and shall be in accordance with commercial practices. text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.2 The following grades are included in this specification: 2.

Ordering Information 3.1 Orders for material under this specification shall include the following information, as required, to describe the material adequately: 1.3 Hot-rolled carbon steel sheet is generally furnished in cut lengths and to decimal thickness only. Coils may be furnished, provided tension test specimens are taken to represent the middle of the slab as required by 5.1.4. The purchaser should recognize this requires cutting the coils to obtain test samples and results in half-size coils. The sheet is furnished to the following size limits: 3.1.1 Designation or specification number, date of issue and grade, 3.1.2 Copper bearing steel, when required, 3.1.3 Special requirements, if required, 3.1.4 Condition — pickled (or blast cleaned), if required.
