My hardness testing was done by a metallurgist that I shipped a sample to.
I’m sure the test was done correcting.
Buying coil steel is all new to me. I was handed some old orders with the specs and had to get some material ASAP. I ordered a small amount from our current suppler to get us through...
I ordered steel to the specs below. The material i got checks full hard.Did I just get the wrong mat. or are my specs the problem?
