Dear All,

 

Please help me in PMI testing for material ASTM A36 thickness over 20.0mm, the composition requirement of manganese is (0.8 – 1.2)%. But result of test is less than 0.8%. Other testings are accepted (tensile, bending, elongation).

 

Please advice me this result is accepted or not.

Thank you in advance.
