ASTM A vs ASTM A – Structural engineering other technical topics – Eng-Tips
Material and Manufacture 4. We posted this document in order to allow citizens to read the laws that govern us. To correlate this to our industry, the industry produces a product and contractors buy the product. Register now while it’s still free! No rejection may be made on the basis of measurements if fewer than ten adjacent deformations on each side of the bar are measured. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
While A can be welded, it does require special pre- and post-weld procedures and the associated expense. Measurements of Deformations 6. This happens because they have the funding and need to “control” their industry.

As an off-topic example, I am on the newly formed F44 committee on general aviation aircraft, as a pilot and consumer. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Test Specimens ; . Advanced embedding details, examples, and help! As far as A is concerned, is there a reason you are looking at A rail steel instead of A billet steel. Download Now Defense manufacturing is all about project manufacturing and project accounting.
When the available scrap supply, or energy prices, or environmental regulations require changes to steel making, the producers will change the ASTM. The main parameter engineers specify is yield strength, followed by weldability, and then ductility for seismic uses. Would using grade 60 be ok? The applicable levels shall be as specified in the contract. Heavier wheel loads, attempts at increased durability, and advances in metallurgy demanded a change in related ASTM specifications.
It’s not so much the standard as what we know about the materials, and the evolution of the materials involved. It is used for fabricating pipe anchors.
When it was withdrawn, there were two grades, namely 50 ksi and 60 ksi, so you may be looking at a much older version. The rebar spec most likely changed when the kinds of retired rail steel and the processing methods changed.
Requirements for Deformations 5. Also, true rail steel bar are not typically fabricated only cut to straight lengthssince these bars are not as ductile as other types of reinforcing steel.
Or use another weldable bar stock if deformations are not required. A number in parentheses indicates the year of last reapproval. A bars are not widely available. Criminal penalties may apply for noncompliance.
Many of the laws in this collection were re-keyed into HTML and diagrams redrawn for increased usability and accessibility. It’s easy to join and it’s free.
For bending properties test provisions of the nearest smaller nominal diameter deformed bar size shall apply. Click Here to join Eng-Tips and talk with other members!
ASTM A616: Rail-Steel Deformed and Plain Bars for Concrete Reinforcement
Search the history of over billion web pages on the Internet. The organization of the committee and subcommittees will be run by the industry mainly the manufacturers of certified light aircraft which may or may not represent the interests of the consumer very well.
Join your peers on the Internet’s largest technical engineering professional community.
Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. CRSI now has a another design engineer liaison to the committee. By Authority of the Code of Federal Regulations: The yield load- shall be recorded when the total gage length under load becomes 1 8.
By joining you are a16 in to receive e-mail. Note that many of these documents had to be procured on the used marketplace.
Originally published as A Current edition approved July 27, A measured length of the bar specimen shall be considered the distance from a point on a deformation to a corresponding point on any other deformation on the same side of the bar. The standard sizes and dimensions of deformed bars and their number designations shall be those listed in Table 1. This Document Posted By Public. Where the line of deformations forms an included angle with the axis of the bar of from 45 to 70 deg inclusive, the deformations shall alternately reverse in direction on each side, or those on one side shall be reversed in direction from those on the opposite side.
Uploaded by Public Resource on July 1, Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
