interpretation of ASTM A182 para 6.2.1

interpretation of ASTM A182 para 6.2.1

(OP)
Hi,

ASTM A182 para 6.2.1 : "Liquid Quenching—When agreed to by the purchaser,liquid quenching followed by tempering shall be permitted provided the temperatures in Table 1 for each grade are
utilized."

Does this concern also F22 Class 3 for which "anneal" or "normalize and temper" is listed ? I n other word Liquid Quenching and tempering is accepted for this grade.

Application : pressure vessel.

Thanks for your contribution.

RE: interpretation of ASTM A182 para 6.2.1

Yes, but only for the normalize and temper heat treatment. Anneal is furnace cooled.

metengr,
you mean that F22 Class 3 can't be Liquid Quenching and tempering but normalizing and tempering. right ?

RE: interpretation of ASTM A182 para 6.2.1

abbver98;
No, this is not what I stated. Normalizing means air cooling. For heavy sections or thick sections of materials  A 182 by virtue of this paragraph permits by agreement between the purchaser and the supplier, liquid quenching to assist in cooling heavy or thick sections that otherwise would not be adequately air cooled to produce a normalized structure before tempering. So, any of the materials in Table I can be liquid quenched by agreement or if it directly states liquid quenching as in the table.
 

RE: interpretation of ASTM A182 para 6.2.1

Is the heat treatment for F22 Class 1 annealed only?

And, is the heat treatment for F22 Class 3 normalized and tempered?

RE: interpretation of ASTM A182 para 6.2.1

F22 material can be liquid quenched and tempered  inorder to achieve the mechanical properties.

The temperature can be  alter according to your mechanical property requirements( yield + hardness ). Always check the microstructure after heat treatment for more uniform structure.
