Thanks! What do you mean by dual certified? Is the MTR require to state that or if mechnical properties and chemistry matches both grades we can use it as a dual certified?
Hi,
I appreciate any feedback on this. I need a ASTM A572 Gr60 material for welding procedure development, but vendor is offering A572 Gr50 which meets all chemistry and mechanical properties of Gr 60. MTR is not stating dual grade. Can I use this material as a dual grade material and qualify...
