ASTM A105/A105M-14 pdf free.Standard Specification for Carbon Steel Forgings for Piping Applications.
This specification2 covers forged carbon steel piping components for ambient- and higher-temperature service in pressure systems. Included are flanges, fittings, valves, and similar parts ordered either to dimensions specified by the purchaser or to dimensional standards such as the MSS, ASME, and API specifications referenced in Section 2. Forgings made to this specification are limited to a maximum weight of 10 000 lb [4540 kg]. Larger forgings may be ordered to Specification A266/A266M. Tubesheets and hollow cylindrical forgings for pressure vessel shells are not included within the scope of this specification. Although this specification covers some piping components machined from rolled bar and seamless tubular products (see 5.2), it does not cover raw material produced in these product forms.
4. Ordering Information
4.1 See Specification A961/A961M.
4.1.I Additional requirements (see 14.2)
5. General Requirements
5.1 Product furnished to this specification shall conform to the requirements of Specification A961/A961M, including any supplementary requirements that are indicated in the purchase order. Failure to comply with the requirements of Specification A961/A961M constitutes nonconformance with this specifica- tion. In case of a conflict between the requirements of thi specification and Specification A961/A961M, this specification shall prevail.
5.2 Except as permitted by Section 6 in Specification A961/A961M, the finished product shall be a forging as defined in the Terminology Section of Specification A788/A788M.
7. Chemical Composition
7.1 The steel shall conform to the chemical requirements specified in Table I.
7.2 Steels to which lead has been added shall not be used 8. Mechanical Properties
8.1 The material shall conform to the mechanical property requirements prescribed in Table 2 and Table 3.
8.2 For normalized, normalized and tempered, or quenched and tempered forgings, the central axis of the test specimen shall be taken at least 1/4 T from the nearest surface as-heat treated. where T is the maximum heat-treated thickness of the represented forging. In addition, for quenched and tempered forgings, the midlength of the test specimen shall be at least T from all other surfaces as-heat-treated. exclusive of the T dimension surfaces. When section thickness does not permit this positioning, the test specimen shall be positioned as near as possible to the prescribed location.
