Poor results with 15n20

Greetings all....
Have been using large band saw blade for knife blades but they don't seem to hold an
edge well, and being hard to sharpen they seem to be hard enough. Have been quenching
in oil at non magnetic/critical temp. and temper at 400-425 F. for one hour. Was once told
to take up to higher temp. before quench. Any ideas?

Thanks
