SA336 F22 CL 1
SA336 F22 CL 1
(OP)
Hi,
I have just received a forging of SA-336 F22 CL 1 material with hardness limitations of 24-28 Rc. The mtr does not have any tensile or yield tests. Is this normal or is my AI going to eat me up over this? Also, the tempering temperature was 1100F while the specification (SA-336) states this material must be tempered at a minimum of 1250F. Do the hardness limitations negate this temperature, meaning it must be 1100F to meet the 24-28Rc?
Any information would be great.

You should have mechanical property data in the form of a material test report. You may only have a Certificate of Conformance from what I gather. For most code applications, this material could not be used in construction because of traceability. Also, review SA-788 because this is referenced in SA-336.
Please review below from SA-788
16. Certification
16.1 The manufacturer shall furnish to the purchaser
the number of copies of the material test report specified
in the ordering information (4.1.4). The following items
shall be reported:
16.1.1 Purchase order number,
16.1.2 Forging identification number,
16.1.3 Material specification number including the
designation and year date, as well as the appropriate class,
type, and grade,
16.1.4 Heat number and analysis,
16.1.5 Results of the required acceptance tests for
mechanical properties,
16.1.6 Results of any required nondestructive
examinations,
16.1.7 Final heat treatment cycle including austenitizing
and tempering temperatures and holding times and
cooling methods if required by the material specification
or 4.2.3,
