I have been assigned with reviewing a job spec, onboard a ship, that calls for welding on EH 36 steel, which I have never heard of, and can find very little info on. And I have a couple of questions, if someone could answer them or point me in the right direction I would appreciate it.

1) What is Eh 36 steel?
2) What rod is used to weld that?
3) Is there any pre or post heat temps I need to be aware of, other than the 400 deg F. max temp?
4) Is there anything else of importance I should know in regards to this steel?
Thanks in advance,

ASTM A 131 GRADE EH36, everything you need can be found in AWS D1.1/D1.1M:2002, Table 3.1 and Table 3.2 - Weld this with Low Hydrogen, E7015, E7016, E7018, E7028 - Minimal preheat, will depend on thickness of plate.

ASTM A131 Covers grades EH36, which is the higher strength grade. Min. yeild 57ksi, Refrence to ASTM A6 Appendix X3 for weldability.
Hope this helps,

OOps, I see Mike has already posted something for you, while I was typing. (the old hunt and peck method of typing)

That's okay John, I had lots of time to sit here and type today myself. Everything ran smooth in the shop today, no road calls, good thing to - it never got over 10 degrees F. today. Now it's snowing to boot.

The snow has stopped here and the sun is out bright, only to fool you into thinking it's a nice day. The wind is whipping around the building and cuts right through ya. Wind chill advisories are out. We only got about 2" of snow, but it's blowing all around.
I'm just "cooling it" today too,

EH36 is also a common ABS grade of steel. It is also in MIL-S-22698. I would normally get something like that from Amercian Alloy Steel.

Do you know the composition of EH 36?

You can find composition and other info here:

A CMTR I just received for EH36 (A633 Gr C) lists C= 0.14, Mn= 1.37,
P= 0.007, S= 0.001, Cu= 0.12, Si= 0.27, Ni= 0.09, Cr= 0.10, Mo= 0.02, V= 0.001, Ti= 0.003, B= 0.0003, Al= 0.030, Cb= 0.028, N= 0.0072
Yield= 53.9k, Tensile= 76.6k, % Elong. in 2"=32.0,
CVN @-40F is 140,150,170. My understanding is the CVN @ -40F is what was required by the EH36 designation. (This is stuff you might be seeing in Portland.)

I am an engineer who worked for ABS and have experience with EH 32. The steel you mentioned I believe is an ABS grade and if you go to there should be joy. I hope this is helpful.

All this discussion reminds me of one thing I always insist to my students. When mentioning a steel on a specification, it should be stated not only the grade or type, (EH36, 1020 or 316, for example) but the applicable standard should also be mentioned, in this case, ASTM A- 131 grade EH36, SAE 1020 and ASTM A-312 Tp 316. In this way, confusion and mistakes will be avoided.
