Grade 660 or as known as A286 is an iron-based, nickel containing superalloy. But because the alloy of A453 Gr 660 contains a high concentration of nickel, the metal is sometimes considered to be a nickel alloy rather than a stainless steel one. In addition to having high strength, the  UNS 66286 Threaded Rod also exhibits superior corrosion resistance properties up to a temperature of 1300°F. Although, in the presence of aqueous media, the  ASTM A453 Gr 660 Stainless Steel Bolt is known to exhibit moderate corrosion resistance properties.

As an austenitic alloy, it is possible to increase its strength by age hardening the a286 stainless steel bolts material. The classification of this alloy is a high strength one, yet, the applications of the A453 Gr 660 Class A/B/C/D Stud Bolts is suited to a low pressured one, in instances where the temperature of the application is elevated. Ideally, the use of ASTM A453 Grade 660 Stud Bolts as fasteners is commonly seen in valve flanges or in pressure vessels. This particular standard covers the inclusion of various elements in the chemical composition of the A286 Stainless Steel Fasteners. Besides its chemistry, like most other specifications, the ASTM A453 Gr 660 Cl.A Stud bolt is required to be put through various tests including tension test, hardness test as well as a stress-rupture test. 

And the specification also has prerequisites that the ASTM A453 Grade 660 bolts conform to other requirements such as the elongation, reduction of area, Brinell and Rockwell hardness, as well as the yield and tensile strength. Moreover, the specification also touches base with the Hardening and solution treatment requirements for SA 453 Grade 660 Material with details in all classes.
