Hi Jay,
Here are a couple of sources I would suggest. Tri-Tech Metals has ALWAYS found what I needed - from steel, titanium, niobium and everything in between.
http://www.tri-techmetals.com/ Ask for Sam.
I've also had good luck with these folks recently.
http://rmat.com/
As for the material defined as 'condition B', this means that the material strength is a result of the 'as rolled' condition. It will be stronger than annealed, but weaker than QT (quenched and tempered) N (normalized) or NT (normalized & tempered). The as-rolled condition doesn't normally define a minimum yield or Ultimate strength (modulus remains unchanged however) or minimum hardness specifically. I will look in MIL-HDBK-5 (the metal properties bible) and see if I can find any additional information.
You might ask T&D if they have a minimum hardness on their material as well as it being 'condition B'. The hardness will allow us to calculate the yield and ultimate strength. Otherwise, if you're open to it, I can suggest a couple of tempers that are easy to machine and would be stronger than the factory style rocker, and have a higher yield than 108 ksi.
