Aldo's 1075

Carbon = 0.76
Silicon = 0.240
Manganese = 0.35
Phosphorus = 0.01
Sulphur = 0.001
Annealed structure is 92% spheroidized carbides.

This steel is hypoeuctectic. It is a good choice for blades that require a high degree of toughness such as choppers. The low Manganese content allows for some pretty active hamon activity.

Basic heat treatment;
1. Heat to 1500 and quench in fast oil. Parks #50, Canola, Mineral oil, etc..
2. Temper twice for 2 hours each time. Temper between 350 & 500 depending on application.

Please keep in mind that this is just a starting point. Experiment with temps. and times to find out what works best for you and your equipment.
