what kind of steel is 1099
Did you know that, within the chemistry specifications of 1095, you can have a steel that cannot fully convert into martensite. The quench rate curve goes all the way to the left side of the graph and touches it. It is possible to have a steel in that family of steel that cannot be quenched fast enough to avoid pearlite.

The 10 indicates the family of steel which is an unalloyed simple steel. The 95 indicates the carbon content. So 1099 would be 99 points of carbon versus 95 points. Which is a rounding error. So 1099 would be 1095. With a little bit too much carbon in it. Which is going to make it that much worse to try to heat treat. You'd want some manganese in there or something like they have in 1084.

I don't know. They're fine steels I guess. Meh
