WOuld anyone out there have a purchase specification for SS304L? Something with requirements on Material Manufacture, Chemical Requirements, Mechanical Requirements, Permissible Variations in Dimensions, Visual Inspection and Repair, Surface Preparation, etc?

RE: Purchase specification
Here's what I do. I go throught he different things I need to spec... Starting with chemistry.. Find SAEJ405, then you cna follow with other different specs to fit your application and remembering that anything outside of the ordinary for industry norms is going to cost you.
Try calling your suppliers and what they usually see for tolerances. I dont know what the various ASTM spec's are for stainless.
At the end of collecting the data I build a single page word document that starts with a summary then continues into details. the summary generally looks like this:
EXAMPLE
CODE
I also am a firm believer in getting A2LA or other certified test reports with each mastercoil. (or whatever the smallest lotsize that could be considered inconsistant.)
RE: Purchase specification
In general the SAE J specs are only used for transportation applications.
The AMS specs are used for aircraft.
The ASME are used for pressure, power and chemical equipment.
and so on
