I don't think that PWHT is mandatory for this grade (I don't have the access to the books right now so I cannot confirm). We have one customer that requires PWHT for major repairs. Time and temperature are the same as the HT for the castings.
We weld with AC.
Note that ASTM A217 also imposes restrictions on the chemistry of weld consumables for the weld repair of C12A castings. Your customer might want to impose the same restrictions on any fabrications.
ASTM A216 WCC is NOT cast iron - it is a weldable grade of carbon steel. (ASTM A216 = Standard Specification for Steel Castings, Carbon, Suitable for Fusion Welding, for High-Temperature Service).
I am a confused about the PWHT. Was the part heat treated after welding or not? If yes, then all...
Hi
I have two DIN specifications with matching Wk numbers, and I am trying to find the source DIN/ISO standard. An extensive search by two of us has so far not found anything. They are
11 NiMoV 5 3, Wk 1.6341
GS14NiCrMo 106, Wk 1.6779
Thanks
Apologies in advance if this is the wrong forum for this question, but I can't find a better one. I previously posted in another forum and was sent here to re-post the question.

I am looking for a copy of BNIF 359-01, and I am happy to pay for it if necessary. It is a French document relating to surface finish of steel castings. I have tried Google with no real success...
@ metengr: Sorry, I don't know the final duty. I will see if I can find out, but we don't always get told this information.
@ stanweld: You are correct, this is for casting repair. This is a large project for us - we are reviewing all melting/casting practices.
I need to develop procedures for welding ASTM A494 CW12MW, the cast version of Hastelloy C276. I hope eventually to have procedures and qualifications in SMAW and GTAW, with and without PWHT. We will be welding our own castings.
Would you recommend welding with matching consumables or would...
A lot of good advice above - don't use thermal excavation techniques, practice on some similar material, carry out a PWHT with water quench. I would suggest you do a full ASME IX WPS/PQR, with bend and tensile tests, but it is worth doing radiography and LP testing first to check weld integrity...
Can anyone recommend a Cr-plater in the UK who could plate a 48" diameter disc weighing approx 1100kg? Base material is ASTM A494 CW6MC (cast Inconel 625).
It sounds to me like you might be supplying a German customer. We have the same issue. We bought a small digital geiger counter from these people: http://www.anythingradioactive.com/geiger.htm
We measured background radiation in a number of locations around the shop. Anything that is shipped to...
What's wrong in specifying grade LCB from ASTM A352/ASME SA352 (Ferritic & Martensitic Steel Castings for Pressure Containing Parts for Low Temperature Service)?
Part of the testing requirements for this grade is a Charpy impact test at -46C.

EN10213:2003 requires impact testing for a number of material grades. Section 7.2.2.1 says that "mechanical properties shall conform to the values given in Table 4 for ferritic & martensitic grades".
Referring to Table 4, (alloy number 1.7379, equivalent to ASTM A217 WC9), it just says "Impact...
The a400 markings on the Monel fittings may refer to the fact that they are Monel Alloy 400. Check with your supplier to see if they can help you out - they may be the ones responsible for the stamping.
