— means no specification of that type covers the alloy and temper. Chemistry only means the material is certified to those specifications for chemistry, but their mechanical requirements don't apply to that temper. Click an alloy for its full details in the Specification Cross Reference.
How to read this list
Each row is an alloy and temper on our Stock List. An AMS specification covers one alloy in one temper, so it tells us exactly what you need. An ASTM specification covers many alloys and tempers, so if your drawing calls out only an ASTM spec, we’ll also need the alloy and temper.
Where more than one alloy is listed (for example 302 / 304), the small tag beside each AMS number shows which alloy it covers.
Where can I get copies of AMS and ASTM specifications?
AMS and ASTM specifications are copyrighted and sold by the organizations that write them, so we can’t send copies. You can buy them directly:
- AMS (Aerospace Material Specifications) are published by SAE International. Search and buy them at sae.org/standards.
- ASTM specifications are published by ASTM International. Search and buy them at store.astm.org.
