You can get a carbide grit bandsaw blade. At work we cut computer floor
tiles that are steel and have a cement like core for strength. We spoke
with the folks at starett and actually sent them samples and they came back
with recommendations for blades. we do not use any lubricant. yes it cuts
down on blade life but it is not as messy and is not that much more we don't
have the blade moving too fast.
this is what we use
our tiles are only about 2' thick but there is also a bit of steel to be cut
