Note: This one-piece cushioned grip "T" handle driver is constructed of a round shank of 17-4 stainless steel with the hex machined on the end and is heat treated to R/C 45-48,

17-4PH is a martensitic precipitation hardening alloy which offers high strength and hardness while maintaining excellent corrosion resistant properties. In this it surpasses the 400 series, more closely resembling the corrosion resistant properties of type 304.

Type analysis of 17-4PH stainless steel
Carbon 0.07% max.	Manganese 1.00% max	Phosphorus 0.040% max
Sulfur 0.030% max	Silicon 1.00% max	Chromium 15.00/17.50%
Nickel 3.00/5.00%	Copper 3.00/5.00%	Columbium & Tantalum 0.15/0.45%

416 stainless Corrosion Resistance:
Useful resistance to dry atmospheres, fresh water and mild alkalies and acids, but less resistant than the equivalent non-free-machining grades. Less corrosion resistant than the austenitic grades and also less than 17% chromium ferritic alloys such as Grade 430. High sulphur content free machining grades such as 416 are totally unsuitable for marine or other chloride exposure
