choose any modern laptop with a good amount of RAM, I suggest no less than 1GB.

You haven't provided us with enough information. This is a steel beam, not an iron beam. Steel can be an infinite number of different compositions and even different alloys. Each will respond differently to chnegs in temperature.

Virtually all steels are quite weldable.  Those alloys with high percentages of certain metals like chromium must be welded in an inert atmosphere to prevent oxidation of the alloying metals.

C. Alloy.  Steel is iron with some carbon added.

Basically, AISI is an association that deal with the busisness of making steel - including how to make steel manufacturing safer and more profitable. ASTM, on the other hand, is a body that defines "standardized" testing so that what one manufacturer calls "304 stainless" is the same material (chemically and physically) as everybody else's "304 stainless". See the "blurbs" on each below.\n~ * ~ * ~\nThe American Iron and Steel Institute (AISI) is an association of North American steel producers. With its predecessor organizations, is one of the oldest trade associations in the United States, dating back to 1855. It assumed its present form in 1908, with Judge Elbert H. Gary, chairman of the United States Steel Corporation, as its first president. Its development was in response to the need for a cooperative agency in the iron and steel industry for collecting and disseminating statistics and information, carrying on investigations, providing a forum for the discussion of problems and generally advancing the interests of the industry.\n~ * ~ * ~\nASTM International is an international voluntary standards organization that develops and produces technical standards for materials, products, systems, and services. It was formed in 1898 in the United States as the American Society for Testing and Materials by a group of scientists and engineers, led by Charles Benjamin Dudley, who wanted to address the frequent rail breaks plaguing the fast-growing railroad industry. The group developed a standard for the steel used to fabricate rails.\n\nToday, ASTM International maintains more than 12,000 standards. The Annual Book of ASTM Standards consists of 77 volumes. Membership in the organization is open to anyone with an interest in the fields the organization services. Members represent manufacturers, users, governments, and academia from over 100 countries.\n\nASTM Standards compliance is voluntary but in the United States, with the 1995 passage of the National Technology Transfer and Advancement Act, the U.S. government is required to use privately developed standards whenever possible. As a result, ASTM Standards have been incorporated into or are referred to by many federal regulations.

Keep checking online. I did print out plans with sources of material last year.  Also, there are finished frames for sale. Maybe Instructables? There are projects for welding bikes,

check for some templates from Microsoft, if you didnt get what you like, use the existing clipart images (group and ungroup them for different designs) to create something you like

Hi. As with most things it depends on the cost of manufacture. : http://www.steelonthenet.com/commodity_prices.html

For industrial designers you can search on http://idsa.org or http://core77.com. Most designers are open to discussing their field and general design questions as long as you are flexible with your schedule. If you contact the chair of the local idsa chapter they can also recommend someone that would help you and regional schools that might be good to look into.\nGood luck

see first u must understand that aisi,astm,en,jis,din all the standards are distinguish as per composition of a steel.\n\nso as per the customer requirement we are developig a standard of a steel.If it answers to a already available standard such as jis,bin,is,etc etc we are following that..\n\nso we must follow the P - no of the steel specified by ASME sec IX..that is the major classification which is globally followed
