People may find these links useful too;

http://www.threeplanes.net/toolsteel.html Has temperatures and colour charts for o1

http://westyorkssteel.com/01.html Has the temperatures/methods for all the major tool steels too, go to products - tool steel

The temperatures will vary slightly between the same grade steels due to slightly different composition, but it won't make enough of a difference to worry about.
