ASTM A 336/A 336M Document Information:
Title
Standard Specification for Alloy Steel Forgings for Pressure and High-Temperature Parts
ASTM International
Publication Date:
Feb 15, 2009
Scope:
This specification2 covers ferritic steel forgings
for boilers, pressure vessels, high-temperature parts, and
associated equipment.
Forgings made of steel grades listed in Specification A 335/A
335M, may also be ordered under this specification. The chemical,
tensile, heat treatment, and marking requirements of Specification
A 335/A 335M shall apply, except the forging shall conform to the
chemical requirements of Tables 1 and 2 of Specification A 335/A
335M only with respect to heat analysis. On product analysis they
may deviate from these limits to the extent permitted in Table 1 of
this specification.
Supplementary Requirements S1 to S9 are provided for use when
additional testing or inspection is desired. These shall apply only
when specified individually by the purchaser in the order.
Unless the order specifies the applicable "M" specification
designation, the material shall be furnished to the inchpound
units.
Specification A 336/A 336M formerly included austenitic steel
forgings, which are now found in Specification A 965/A 965M.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.

applications, see related Specification SA-336/SA-336M in Section
II of that Code.
*A Summary of Changes section appears at the end of this
standard.
