SF BHT,
Thank you for the pics. You can get that blade up to around 975 degrees F before any damage to the temper starts.*
Good job too.
*This is a secondary tempering range for that steel which we do not use because at that temp, the chromium continues to form carbides, drawing usable chromium from the matrix of the steel resulting in a slightly lowered stain resistance. It still has all it's edge holding and toughness.
