Manufacture6.1 Welding ProcessCarbon steel chain may be made bythe forge welding, electric welding, or gas welding process.6
18、.2 Heat TreatmentGrades 30 and 43 do not require heattreatment, but may be heat treated at the manufacturersdiscretion. Grade 70, after welding, shall be heat treated. Heattreatment shall include quenching and tempering as describedin Definitions E 44.7. Dimensional Requirements7.1 The chain shall c
19、onform to the dimensional require-ments specified in Tables 1-3 for the appropriate grade and sizechain.7.2 DiameterThe diameter of the material from which thechain is manufactured shall not be smaller than the materialdiameter listed in Tables 1-3 within the following tolerance:7 %. Oversized mater
20、ial may be used for all applications.8. Workmanship, Finish, and Appearance8.1 The chain at the time of shipment shall be free ofdiscontinuities that would prevent the chain from enduring theworking load limit forces.8.2 The manufacturer may apply a surface treatment orcoating of their own choice fo

Mechanical Requirements9.1 Proof TestAll chain shall be tested to at least the proofload prescribed in Tables 1-3 for the appropriate grade and sizechain. When so tested it shall withstand these loads withoutloss of c
22、hain integrity. Links or chain segments that do notwithstand the proof test load shall be removed from the chain.9.2 Breaking ForceThe breaking force test specimen shallconsist of a length from the lot containing at least the numberof links in Table 4. All chain that is heat treated shall be in theq
