DIN 10088-1
DIN 10088-1
(OP)
Hi All!
We are looking for an equivalent AISI grade for the subject material. Would anybody know if there is an equivalent AISI/UNS number. It is also identified as X4CrNiMo 16-5-1, which simply means 16% Cr, 5% Ni & 1% Mo. Is there any mill in the US making this grade?
I guess the next question that follows would be is there any material data available providing forging temperature, Heat treatment and any machinability issues. We plan to anneal after forging to facilitate machining (not sure if its the right thing to do). Required finish hardness is 32 to 35 HRC and YS 108 ksi (min).
Appreciate any or all help.
Thanking y'all in advance,
Regards

Machining is not a concern,but remember to stress relieve after machining if you plan to oil quench and harden followed by tempering. In my opinion you can achieve your specs by air hardening,but ensure uniform cooling..

RE: DIN 10088-1
I checked on Carpenters data sheet and found a somewhat similar steel (a casting variety, I'm told) conforming to UNS S45000. I was wondering if this grade could be offered
and yet achieve mechanicals (YS 108 ksi, Hardness 32-35 HRC,
Charpy 31 Ft-lb @ 4deg F in 3 samples). We have no experience with UNS S45000. Can any one share your experience with this grade??
The other grade that has been touted is the 15-5 PH grade.
I guess that may work and again we have little or no exposure to this grade of steel. Appreciate any help in this regard
We are trying to find alternatives for X4CrNiMo 16-5-1 in the US market to offer to our customer. Any pointers would be greatly appreciated.
Thanks again,
Regards

Yes we are considering alternatives for X4CrNiMo 16-5-1 on account of the long leadtimes for procurement from Europe.
Local mills are prepared to cast them if we have the right quantities, which, unfortunately, we do not have. We shall try our luck with AK Steel, Allegheny technologies.
Answering TVP's questions; yes there is welding involved at a later stage, though our role ends with the supply of forged block. The end use environment is corrosive oil well/refinery. We are trying to get them to accept UNS S45000 or 15-5PH grade steel. While we wait on the customer to get bcak with their decision, we are working on the processing aspects. Any suggestions on this is always welcome.

What would be a good place to get some information on the machinability of X4CrNiMo 16-5-1 grade steel?? I'm not finding relevant info' on Google. Appreciate any help or pointers in this regard.
