Dear All,
In a vessel we used SA 516 Gr. 70 Plate for Dished ends (12 Thk).
Chemical Analysis (Lab Tested) of Plate (values) observed are,
Chromium (0.018 Req. 0.34 max) ,
Nickel (0.021 Req. 0.43 max),
Molybdenum (0.008 Req. 0.13 max),
Copper (0.013 Req. 0.43 max).
Vanadium ( Nil
Niobium ( Nil
Niobium ( Nil
Titanium ( Nil
Our customer is not accepting the material Since the above elements are much lesser than the specified.
We explained 1) since as per spec.only maximum values are specified it is acceptable.
2) CE is within limit.
But he is not accepting the same.
What to do ? Please, help me.
Regards,
Vikas.
