Mfg specs are well and good, but nothing supercede s a qualification test.
True, its a norm for a filler metal to exceed it's designated minimum tensile strength.
The problem is, that as carbon and metallic alloy ingredients increases for higher tensiles, ease of operation decreases. AND, bead appearance suffers too. Hence more definition of ripples and spatter size and quantity. There just aint no free lunch!
Why was the D2 suffix selected? Was it something the shop had on hand in the store room? Did that slick salesman at the LWS suggest it?
Dig through mfg specs and go for a higher nickel content for smoother beads.
Remember though, nickel = $$$$.
