Material Specs - how to look them up? 2

[paulberrylively]

I continually am faced with material specs. I do not know how to look them up. I am a member of ASM but I can not figure out how to use their website for looking up specs. If I see "per ASTM Spec No. A 27 Grade 60-30" for instance or DIN numbers or AMS 5662 how can I find the information about the materials? Is there a book I have to buy or a website that is easily referenced for this? If I see "per asm..." or "per ASTM..." how can I find info about the stipulations that these documents call out??

If you are talking of steels a useful comparison reference is Stahlschlussel (Key to Steel), 20th Edition
available from ASM.
But one must beware that equivalent specifications are seldom identical.
Another resource is Global IHS at

http://global.ihs.com/

where you can get the Title of the Spec. to see what is it about.
Some commercial firms publish their own comparison tables, to be taken with much care.

If you need to work with these specifications in order to ensure compliance of your products or your designs it is wise to have a current copy available. ASTM standards used to be published as collections of related subject areas but now you can go to the ASTM web site and download copies of individual standards direct to your desk. The cost varies with the size of the document.

ASM offers several good references for cross-referencing standards, but you need to purchase the individual standards in order to know the requirements. Global Engineering Documents (part of IHS) allows you to purchase individual standards, while the IHS part allows you to purchase entire collections (ASTM, SAE, DIN, etc.) or portions of collections.

faq330-286 Will give you some other links in addition to

supplied by ctopher. But typically the best you can hope for is the title of the spec and therefore have to buy a particular spec to get the detail information needed.

Some of the other posts tell you where to buy.

Matweb is definitely the easiest one stop spot for Material specs. They break it down pretty throroughly as they will not just list Polypropelyne as a material but they supply tons of types of PP's and also offer specs by brand name. They also include who supplied the spec so you can judge the quality of the information.

Thank you. I need to invest some time perusing Matweb to understand better how to use it. I have done a little in the past but it has been too long.
