ASTM A182/A182M is a standard issued by the American Society for Testing and Materials (ASTM), applicable to forged or rolled alloy steel and stainless steel piping components for high-temperature service, including flanges, forged fittings, valves, and similar parts. This standard covers the chemical composition, mechanical properties, heat treatment requirements, and testing methods of the materials.
Standard Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service
This specification covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves, and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications that are referenced in Section 2.
For bars and products machined directly from bar or hollow bar (other than those directly addressed by this specification; see 6.4), refer to Specifications A479/A479M, A739, or A511/A511M for the similar grades available in those specifications.
Products made to this specification are limited to a maximum weight of 10,000 lb [4540 kg]. For heavier forgings and products for other applications, refer to Specifications A336/A336M and A965/A965M for the similar ferritic and austenitic grades, respectively, available in those specifications.
Several grades of low alloy steels and ferritic, martensitic, austenitic, and ferritic-austenitic stainless steels are included in this specification. Selection will depend upon design and service requirements. Several of the ferritic/austenitic (duplex) grades are also found in Specification A1049/A1049M.
Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order.

- A All values are maximum unless otherwise stated. Where ellipses (..) appear in this table, there is no requirement, and analysis for the element need not be determined or reported.
- B Niobium and columbium are interchangeable names for the same element, and both names are acceptable for use in A01.22 specifications.
- C Grade F 2 was formerly assigned to the 1% chromium, 0.5% molybdenum grade, which is now Grade F 12.
- D The present Grade F 5a (0.25 max carbon) prior to 1955 was assigned the identification symbol F 5. In 1955, the identification symbol F 5 was assigned to the 0.15 max carbon grade to be consistent with ASTM specifications for other products such as pipe, tubing, bolting, welding fittings, and the like.
- E Applies to both heat and product analyses.
- F For Grade F 22V, rare earth metals (REM) may be added in place of calcium, subject to agreement between the producer and the purchaser. In that case, the total amount of REM shall be determined and reported.
- G The ratio of Titanium to Nitrogen shall be ≥ 3.5. Alternatively, in lieu of this ratio limit, Grade F 23 shall have a minimum hardness of 275 HV (26 HRC, 258 HBW) in the hardened condition (see 3.2.1). Hardness testing shall be performed in accordance with 9.6.3, and the hardness testing results shall be reported on the material test report (see 18.2.5).
- H Grade F 316Ti shall have a titanium content not less than five times the carbon plus nitrogen content and not more than 0.70%.
- I Grade F 321 shall have a titanium content of not less than five times the carbon plus nitrogen content and not more than 0.70%.
- J Grades F 347 and F 348 shall have a niobium (columbium) content of not less than ten times the carbon content and not more than 1.10%.
- K Grades F 347H and F 348H shall have a niobium (columbium) content of not less than eight times the carbon content and not more than 1.10%.
- L Grade F 347LN, Grade F 347LNCuB, and Grade F 317LNCb shall have a niobium (columbium) content of not less than 15 times the carbon content.
- M % Cr + 3.3 × % (Mo + 1/2 W) + 16 × % N = 41 min.
- N Chromium Nickel Balance is defined as CNB = (Cr + 6Si + 4Mo + 1.5W + 11V + 5Nb + 9Ti + 12Al) – (40C + 30N + 4Ni + 2Mn + 1Cu).
- O Al + Ti shall be 0.85% min: 1.20% max.
- P The method of analysis for nitrogen shall be a matter of agreement between the purchaser and the manufacturer.
- Q % Cr + 3.3 × % Mo + 16 × % N = 41 min.

- A Where ellipses appear in this table, there is no requirement, and the test for the value need neither be performed nor a value reported.
- B Determined by the 0.2% offset method. For ferritic steels only, the 0.5% extension-under-load method may also be used.
- C For sections over 5 in. [130 mm] in thickness, the minimum tensile strength shall be 70 ksi [485 MPa].
- D For sections over 5 in. [130 mm] in thickness, the minimum tensile strength shall be 65 ksi [450 MPa].
- E Longitudinal. The transverse elongation shall be 25% in 2 in. or 50 mm, min.
- F Longitudinal. The transverse reduction of area shall be 45% min.
- G Maximum section thickness at the time of heat treatment; see 7.4.
