EN S355N - US grade equivalent

EN S355N - US grade equivalent

EN S355N - US grade equivalent

(OP)
What is the US grade equivalent to EN S355N material.
We have an ASM 'Worldwide Guide To Equivalent Irons and Steels' 3rd edition, and I could not find it. For the future where can you find equivalents for this EN series?

RE: EN S355N - US grade equivalent

Look in the table 'Equivalents of Carbon Steel Qualities,' under the Europe heading, in the EN 10113-2 column.  Looks like this was previously S355 J2G3 in EN 10025(93). Cross-lists to DIN St52-3N, etc.

Thanks for the help. It says on the drawing to Manganese Phosphatize the material. Is that some hardening process?
Is the material received that way for machining, or is it done after machining? How do you specify it to whomever? Do you just say I need this manganese phosphatized, or do you get more specific (like case depths, Rc, etc.)?

RE: EN S355N - US grade equivalent

S355N is normalised , fine grain structural steel per EN 10113-2. Is for low temperature application. No real equivalent in ASTM , but close to A 808

I found the material thanks to the site kenvlach linked me to. It cross referenced to a E36-3 France which is a High-Mn 1513 carbon steel.

Also I figured out what Mn-Ptize is. Basically it is a conversion coating to help prevent corrosion, galling, etc. It chemically converts the surface of the metal. I take it this process needs to be done after machining the part?

RE: EN S355N - US grade equivalent

Yes, the phosphating operation needs to take place after machining.  Phosphating is very common pre-treatment, with iron phosphate, zinc phosphate, and manganese phosphate all used for different purposes.  You should obtain more information about the Mn phosphating.  Specifically, what coating weight is needed?  Is the phosphate supposed to be subsequently oiled?
