GM Material Equivalent
GM Material Equivalent
(OP)
I have a drawing for Weld Nuts that specifies the material type as GMS218M. G.M. is the end user so I am assuming that the material is a GM specification. There were not hits at all on the internet for this item. Can anybody tell me what the SAE or ASTM equivalent would be for this material?

Perhaps this is a clerical error with typing or writing or transcribing, etc.

RE: GM Material Equivalent
I found GM218M which is a spec governing "Performance requirements for external acrylic ornamentation / second surface decorated"
Contact your buyer or your DRE.

RE: GM Material Equivalent
I checked with the requisitioner and the correct spec is GM6218M grade 340. We assume the 340 refers to HSLA material, but we would need to procure it in a Ø 1.25" bar. My initial material source stated that he has never seen 340 HSLA in a bar form of that size. Could he be mistaken, or is the engineer possibly specifying the wrong material?
