Scope

JB/T 8837-2000 This standard is a revision of JB/T 8837-1999 "Metalographic Examination of Internal Combustion Engine Connecting Rod Bolts". This standard specifies the technical requirements, inspection methods and metallographic structure of internal combustion engine connecting rod bolts. This standard applies to internal combustion engine connecting rod bolts made of 40Cr, 35CrMoA, 15MnB, 15MnVB, 20MnV and other steels, and the metallographic structure inspection after heat treatment. This standard was first released as NJ 309-83 on July 25, 1983, and the standard number was adjusted to JB/T 8837-1999 in April 1999.
