Grade 8

With a minimum tensile strength of 150 ksi and minimum yield of 130 ksi, Grade 8 has a greater tensile and yield strength compared to other steel grades such as Grade 2, Grade 5 and B7. All America Threaded Products will dual certify to ASTM A354 BD and SAE J429 Grade 8. The Grade 8 material from AATP is 100 percent domestically melted and manufactured. The chemistry and mechanical properties will meet the requirements for both specifications. Chemical requirements are provided from the steel mill, while mechanical requirements are provided from our third-party vendor responsible for heat treating after parts have been threaded.

Material certificates and material test reports are available upon request.
