Add additional requirement during purchase that hardness value of xxxx HBW – xxx HBW is to be tested at 1/4T. Now we tested at surface.
Ruja /Supat: need to convince customer that ¼ T is the acceptance by high end users like
oil & gas , marine and off-shore industries. And the result of mechanical test is a representative of the bar. To get core hardness is not easy and if insist, some mills may not do it. Even if they do, they will ask for higher price due to more care and control; and more heat treatment processes.
Please think of a way to discuss with AXO
