Materials & Welding

Dear Friends, I have below mentioned queries regarding Re-certification of ASTM Materials e.g. A36 Plate material to latest edition. 1. Can ASTM Material be re-certified to its latest edition same like we do in ASME Material?  2. Can Manufacturer of ASME Stamp Holder Re-certify the ASTM Material? 3. Can Manufacturer Re-certify MTC's belonging to BS EN10204 3.1? Waiting for your replies.

Yes As it is in the same P No and F No catagory But you have to write the WPS addressing 304L base and E308L welding consumables  with supporting available PQR of 316L (provided  you do not require to use this WPS for Impact requirement) Regards Hegde p.B.

OK 48 is E 7018 and is with Mn up to 1.2%  The impact strength is 80 J at  -40 C.  UTS  values are app. 540 N/sq.mm. Works win DCEP, DCEN & AC 90 OCV.   OK 55 is E 7018-1 and is with Mn up to 1.5%  The impact strength is 80 J at  -50 C.   UTS values are app. 590 N/sq.mm. Works with only DCEP & AC 65 OCV t U will get the values after a prolonged PWHT. As U have seen, impact strength is higher in OK 55 and recommended  where more impact is needed. The baking temp. weld ability is same except that, u will  end up paying  bit more for OK 55.There is no necessity to change to OK 55 when not needed.  Regards, C Sridhar.

This type of requirement is generally raised by the client when they require minimum certification of the material from the manufacturer. Further, this requirement is generally mentioned when providing the Purchase order to the manufacturer and it is clearly state to mention EN10204 TYPE 3.1 on the MTC.  If your PO to the manufacturer has included this requirement then definitely they should provide with MTC mentioning EN10204 TYPE 3.1 on it along with the manufacturer seal/stamp & signature to you.
