MS-264 ....where do I get it? 1

[TxAggie93]

I am looking for a source of MS-264-35-SF. We are building some prototype parts for DaimlerChrysler and the gentlemen we are working with say that they do not have a source for this material currently. Is this milled exclusively for Chrysler somwhere? Several large scale distributors across the country have been of little or no help. If anyone is aware of a source, please advise. Thank you!

I take it that you do not actually have a copy of the MS 264 standard, so I will start by explaining the nomenclature. First, the grade is properly called-out as follows:

MS 264-035 SF

The S indicates that the steel is to be a Structural Grade with specified minimum and maximum tensile yield strength, minimum ultimate tensile strength, and minimum % elongation. The 035 is the nominal tensile yield strength in ksi (35 ksi). The F indicates that the steel is to be killed, made to a fine grain practice, and with sulfide inclusion control.

Next, there is no specified chemical composition for this grade. A list of ASTM standards (ASTM A 568, A 715, etc.) is referenced for the required chemical compositions.

The reason that you are having difficulty in obtaining this steel is because you and your vendors are unfamiliar with the standard. A simple SAE grade 1010 steel can be produced to meet the requirements of this standard. I suggest you obtain MS-264 and familiarize yourself and your vendors with its requirements. This standard can be obtained from AutoWeb at the following address:

TVP, I have obtained a copy of the complete material spec. Funny how that makes things a little easier, huh? Thank you for shedding light on the nomenclature for me. I appreciate it!
