The 1030 alloy is a standard low carbon alloy with the right toughness value of about 50 ft-lbs.  It is a low cost alloy,  but it doesn't meet the other performance requirements -- 

• The yield strength of the 1030 alloy is 50 ksi, less than the desired 140 ksi
• The hardness is only about 8 Rc, much less than the 35 Rc required for wear resistance.
• The brittle transition temperature is about -15F, much higher than the required -50 F.

The 1030 is not the best alloy for the ice cleat.
