High ASTM A333-6 Impact Test Results
High ASTM A333-6 Impact Test Results
(OP)
Have received a mill certificate from a steel supplied for DN400 ASTM A333-6, DN40 XS.
The impact test results for a 10x10mm specimen at -45degC are 1) 298J, 2) 298J and 3) 298J.
This seems indefeasibly high. It also seems unfeasible that all 3 test results are identical in value.
I am querying the mill on the result.
Has anyone seen impact results this high for A333?

When you buy price wise from China without verifying the mill practices and follow up with independent inspection, expect the worst.

Thanks for your responses. So i got an independent NATA accredited third party to repeat the testing. The exact same result was obtained for the three specimens. I rang the third party and they confirmed the specimens did not break on a 300J machine. The 298J reading was recorded as the specimens slightly deformed when struck.
CWeng, sounds like this is in line with what you are saying.

When this happens to us in testing we flag them with a note saying that test was out of range and in excess of XXX.
