steel grades and standards
steel grades and standards
(OP)
Hi,
I'm new in steel business. What is the difference between steel grades and standards?
I'd also appreciate if you could recommend the best cross reference between standards of different countries.
Many thanks.

RE: steel grades and standards
The best sources of cross-reference information on steels are Stahlschlüssel and ASM's Worldwide Guide to Equivalent Irons and Steels. Perform a search of this site for links to purchase these references.
RE: steel grades and standards
You need to know which ones are the most common in your industry.
In the US the major stadards organisations are ASTM, SAE, and ASME.

I love materials science!

Heat exchangers used to be governed by HTRI/ HEI/ TEMA. But now ASME VIII/1 rules, and I hear that TEMA is no longer to be followed. Of course, certain sections of TEMA are still necessary in design.
There are cross-references between ASME-BPV and API Standards, right?
Certain countries/ regions of a country have their own local legislation/ regulations [i]concurrently[/] running with national and international standards.
Like that was not enough, there are instances where it is debated if a particular standard is applicable for the particular equipment or a component of the equipment.

Then again it may be sort of a litmus test. By finding out if a young metallurgist is capable of learning, using, interpreting, and X-referencing the different specs/standards, it may highlight their eventual abilities/strengths, while providing a means for uncovering their weaknesses.

It would have been better if you posted this in a separate new thread.
Btw, this may interest you.

Perhaps, you could contact Steel Technology Department, Central Metallurgical R&D Institute, Helwan, Cairo.

Most of it however is simply a lack of foresight. People didn't plan on the materials being used around the world for many different industries.
The use of UNS numbers for alloy designation is a step in the right direction.

For standards cross reference, and definition of chemical/physical properties, I really like http://my.metalinfo.com
There is a subscription fee, but we have found it to be well worth the cost.

You have to start with the UNS book. It lists all alloys and has excellent spec cross ref in the back.

(print only is half of the price)
I also have Stahlschlussel. I don't upate it each year, but as long as it is only a few years old it is fine.
http
In addition there is 'Handbook of Comparitive World Steel Standards'. This book has been revised and is very useful.
htt
Another good ref is the 'Worldwide Guide to Equivalent Irons and Steels'.
http
The fifth is Woldmans, of course. This venerable reference is not often needed, but sure can save your butt. It is the only one organized by tradename.
