9260 is an alloy steel with about 2% silicon. It also has about 1% Manganese, so it should not produce a hamon. It may produce a quench line if a partial quench is done, but a clay coated blade should not show much of any true hamon.
Austenitize at 1600F and oil quench 9260.
Forge it hot, as the Si will make it crack if hammered below 1700F.
It is a good steel for big blades, and makes tough choppers and camp knives. Work it and HT it like 5160 and you will get good results.
I have some 9260 from Bill Moran, and use it to teach new smiths how to forge.
