Material Specification Equivalents US - DIN

[Carburize]

Can anybody provide the DIN equivalents to the following ASTM standards?

ASTM A-36
ASTM A1011
ASTM A-572
ASTM A-992
ASTM A-53
ASTM A-29
ASTM A-6

C,

I have been out of the office for the past 3 days, which is why I have not already responded to this. I will send you some more detailed information when I return next week. What I can tell you now is that DIN along with the rest of the European SDO's are collaborating on European Standards (EN), so everything will be DIN EN ... And with this, the standards are organizaed differently. For example, ASTM A 29 covers hot-rolled steel bars. There is no exact equivalent EN because they differentiate based on end-use. For instance, the following standards all cover hot-rolled bars to some extent:

DIN EN 10263
DIN EN 10083
DIN EN 10084
DIN EN 10085
DIN EN 10087
DIN EN 10088-3

Check out the exact titles using Global, etc. I am not sure what the status is regarding tolerances and dimensional requirements, because a draft standard called Euronorm 60 is referenced in my versions of these documents. I'll try to give you some better information next week.

TVP _ believe the equivalent to A6 is now EN 10025-1 which incorporates the general supply conditions for all product forms.

Carburize,

EN 10025-1 should be the equivalent of ASTM A 6. EN 10111 is the equivalent to ASTM A 1011. EN 10149-1, -2, & -3 cover HSLA steels similar to ASTM A 572. I am not familiar enough with ASTM A 992 and A 53 to be able to offer equivalents. Good luck.

ASTM A-36 : st 37-2
ASTM A1011 : ?
ASTM A-572 : st 44-3 / st 44-3 U / st 50-2 / st 50-2 G etc.
ASTM A-992 : ?
ASTM A-53 : st 35.8
ASTM A-29 : ck 45
ASTM A-6 : ?

I have nearly all corespondance but can you give me more details.
the best is to look for the "Sthalshlussel" this is a german dictionnary with all existing steel and their correspondance with european or american standards.

silouane,

The ASTM standards that Carburize listed do not correspond to one particular grade, but instead discuss the requirements for certain types of products, and therefore many different grades. For instance, you list Ck45 as the DIN equivalent for ASTM A 29, but in fact, there are 75 different grades of steel listed in ASTM A 29, of which only one (1045) corresponds to Ck45. Also, all of the grades that you listed are the now obsolete DIN grades which have been superceded by various DIN EN designations.

TVP,

you are right and I know that, that's why I advise to look at the sthalshlussel because this book give correspondance with each specific grad and chemical composition.
More over, there is an ambiguity when we speeak about DIN EN and DIN. DIN designation is not complitely obsolet because still a large number of industry use the old DIN designation.

If CARBURIZED need references to the DIN I can help. If he means DIN EN, then you already answer the question.

Both of you have been very helpful - the "old" DIN numbers are what I needed. I am being offered alternative material designations for fabrication of a structure in north Africa and they seem to be still using the early DIN numbers for their structural materials.
