Customer has specified that they want material 316ss for a forging and material must indicate NACE MR0175 and EN 10204 3.1b - Dimension ~27" Diam. x 7" thick
Both of these are new for us.
I have determined that there is no “NACE Test” that can be used to certify that a material meets MR0175. MR0175 is essentially a listing of material that have been deemed acceptable. Acceptable materials are always listed with some type of hardness requirement, and there are often other stipulations regarding hot-or-cold working, heat treat conditions etc.
It appears that 316ss needs to be in the 235HB range.
Am I missing something, it seems to simplistic.........?
EN 10204 – 3.1b has been replaced by 3.1 – This details inspection certificate type. Basically declares that the product supplied are in compliance with the requirements of the order and in which we supply test results. You may have to ask for these as there are none on the form you gave me.
Same as above, customer never gave any mechanical requirements................seems too vague?
