Metal Specifications Reference and Info

[Tech.Illus]

Can anyone recommend the best complete resource for Metal specifications, properties, standards, etc?
I am mainly interested in those used to make valves: Brass, Carbon Steel, Stainless Steel, Ductile Iron.

From ASM International: the companion books "Worldwide Guide to Equivalent Irons and Steels" and "Worldwide Guide to Nonferrous Metals and Alloys". These should help identify alloys on composition, tensile, and hardness requirements but once you narrow down you will probably need to obtain the actual specs of interest for all properties.

I own a copy of the UNS book

https://www.astm.org/BOOKSTORE/PUBS/DS56L.htm

(if you are a member of SAE you can buy it from them also).
It lists alloys by UNS, and gives the composition, and lists the applicable specifications.
In the back are cross index by Common Trade Name and many different specification systems.
You will still need the product specs to know properties and testing but this is an excellent tool for helping navigate.

ASTM is the primary source for metal specifications . But it will be expensive to get the books for all the materials in your list.It depends on what you mean when you say "valves" ; I think Cr;Mo forgings ,or at least carbon Mo. For wellhead valves you must have the API 6 Specification.

If you are buying or selling to these specs you need to own copies anyway.
If you join ASTM they will send you one volume as a part of your membership, and the membership fee is less than the cost of many of the volumes.
Maintaining a tech library is big deal and expense.
While you can often find free pdf of many specs out there, but these docs are all copyrighted so be careful.

The most complete source are the ASTM standards. ASTM breaks them up into individual standards by materials and forming methods.

So, for example most cast carbon steel valves are made to ASTM A216 352. Austenitic stainless steel valves are made to ASTM A351. Martensitic stainless steel valves are made to ASTM A217. Nickle based materials are in ASTM A494. All of these standards and most of the standards that they reference can be found in volume 1.02. I think the forging standards can be found in 1.05.

The same information can be found in the ASME standards but those tend to lag behind the ASTM and in the ASTM it easier to find everything in my opinion.

Looks like Tech.Illus would need to buy a minimum of 3 ASTM volumes to cover the range of materials mentioned. I again will mention what a great tool the Worldwide Guides are because they summarize international standards (including ASTM, SAE, and AMS American standards) that apply to an alloy and also list most common properties (composition, tensile strength, and hardness) within those standards. The UNS book Ed mentioned is a really great guide if you only know or want composition (probably the reference I use most in testing) and leads me to alloys to look up in the Worldwide Guides.

I'm surprised no one has mentioned ASME II (2019 - Current) - All materials, properties, compositions etc., are in here.

Also, maybe more unknown in USA, there is an established publication from Germany entitled Stahlschlüssel or 'Key to Steel' (keytosteel.com) It is multilingual and is a hefty document, which provides cross reference, composition etc., to almost the entire worlds metallic materials. It's expensive but you may find an out of date copy online.



Per ISO-4126, only the term Safety Valve is used regardless of application or design.

ASME B&PV Part II has code-applicable material specifications covering ferrous alloys (Section A), non-ferrous alloys (Section B), and welding (Section C). Sections A and B are mostly identical specifications to equivalent ASTM specs, though some have differences as noted. Section C is equivalent to AWS specifications. Most intriguing to me is Section D, which provides design limits and material properties over temperature spectrum for materials in Part II as applied by the other parts of the Code: this is to be used by designers in selecting acceptable materials.

I think that one reason that we didn't go straight to the B&PV Code is that each section is about $1k.
Where as I can by a Stahlschlussel, UNS ref, Woldmans, and for or five vol of ASTM for less than that $1k.
