= ASTM A453 Grade 660 = ASTM A453 Grade 660 is typically known as alloy a286 with various trade names and specifications equivalent to UNS S66286. A453 Grade 660 material is produced in various other forms like wire rods, round bars, shafts, castings, forgings, threaded bars, threaded rods, wires, tubings, sheets, plates, welding rods, hex bars, Rivets & Springs. A453 Class A,B & C Bolting intended for high temperature use are stress rupture tested for 100 Hours at 650°C in finished condition. A453 Grade 660 D Bolting are typically produced in double aged condition meeting NACE MR 0175 requirement of hardness 35 HRC Max in accordance with API 20F BSL2 & BSL3. Additionally Class D Bolting are charpy impact tested -196°C with 40 joules as the minimum qualifying requirement.
