metal property sources 1

[marmon]

Im looking for a website that shows materials and the properties they have? I'm looking the web for different ASTM#'s and come up with all kinds of stuff.
I tried metweb but i can't seem to find A513-5 on it or even A106b. I come across this lots and waste a lot of time trying to find info about different materials

Thanks

You need to purchase the actual ASTM documents to obtain the information within them. Some Internet sites may list some of the properties, but you aren't going to find everything you need. MatWeb is one of the largest free sources of information, so if you don't find something there, it will be harder to find it elsewhere. Please don't write back saying you can't afford them. Compared with other standards organizations, ASTM documents are inexpensive. All standards are affordable when viewed from the perspective of the total costs to conduct commerce.

The only statement to add to CoryPad's comprehensive post is that the cost of Codes and Standards (not just ASTM Standards)is the cost of doing business if you are in procurement, fabrication or testing of materials. Codes and Standards bodies have publication costs and other expenses that need to be recovered just like any other business.

marmon,

A513-5 means ASTM A 513 Type 5. ASTM A 513 is a standard for welded tubes and Type 5 specifies that the tubes are subequently drawn over a mandrel, thereby homogenizing the weld seam, reducing the thickness, improving surface roughness, etc. ASTM A 513 lists many different chemical compositions that are able to be used for Type 5 (Mandrel Drawn) tubing. ASTM A 106 is a specification for seamless steel pipe suitable for high temperature use. Different grades have different mechanical property requirements.

As a tip, join ASTM. It cost $85 (at least it did last year) and you get one 'free' book as a member. Individual volumes cover entire categories of products and usually cost ~$200 each. You can cover all iron and steel products in various forms with three volumes.
Remember, the standards will give you the minimum strengths. They do not contain any physical properties, and they don't address typical or actual mechanical properties.

It seems odd that to find extensive info on various materials is so difficult. I would think that major steel suppliers would have all this info readily available for customers so they can select correct materials for various jobs. It would make it easier for the engineer as well, to see what is readily available, and what is not.

Having to convert US standards to European ones, one of the best webs I've found is

Check out

http://www.CASTI.com.

They publish lots of materials info about the various material standrads around the world.

marmon,

What do you consider to be "major steel suppliers"? Steel mills like US Steel or Nucor Steel that mostly produce raw material forms like hot-rolled sheet coils or cold-drawn steel bars? Or do you mean suppliers of fabricated steel semi-products like welded tubes or seamless pipes such as Plymouth Tube or Tenaris? Some steel mills like US Steel and Dofasco are relatively vertically integrated in that they produce both raw materials (slabs, billets, hot-rolled sheet, bars and wire rod, etc.) and semi-finished products (welded and drawn tubes, cold-rolled sheet that is electrogalvanized and continuously annealed, etc.). The point I am making is that 1) it is difficult to parse out what a steel supplier is supposed to provide in terms of properties as it will depend significantly on how the steel is processed by others in the value chain and 2) some steel producers do have a great deal of information on their websites. Since you asked specifically about tubes and pipes produced to specific ASTM standards, you received recommendations on how to obtain the ASTM standards, and what the designations actually mean.

Plymouth Tube and Dofasco Tube (now ArcelorMittal Tubular Products) both have a great deal of technical information available on their websites specifically for tubes produced to ASTM A 513, so it just depends on what you need in order to determine where to look. I am including two links for the above mentioned companies:
