Grade 660 is a precipitation-hardenable super-alloy based on iron. The material finds use in applications requiring high strength, paired with corrosion resistance up to 1300 °F (700 °C). Besides, the alloy has other favorable properties, including excellent fabrication characteristics, low-temperature non-magnetic strength [down to -320 °F (-196 °C)], and ductility.
The chemical composition of Grade 660 forged material shall be made on samples which correspond to the top & bottom of the re -molten ingot used to the make the part according to ASTM E354, ASTM E1473, ASTM E2465 and ARP1313 for trace elements (lead, bismuth and selenium). Others than abovementioned standards may be used provided THAT they are approved by the purchaser.
Chemical analysis performed on final product shall conform to the variations specified in ASTM B880.

Qualification of manufacturing procedure of ASTM A453 Grade 660 forging parts
The Manufacturing Process Plan (MPP) shall be submitted to the approval of clients Material
& Process Engineering dept. clients before qualification procedure begins. It shall detail at least
the following:
• type of ingot (supplier, manufacturing process, dimensions, and tests to beperformed);
• forging process;
• heat treatment process;
• tests on component.
In general, dissection of the first piece within the terms detailed in the part specification is required.
This activity may be omitted, upon decision of clients, if the supplier has already proven to be able to successfully produce components of similar shape, dimensions and manufacturing
process.
