Stainless L-Keys (17-4 ss)

FractionalAvailable individually in 7 sizes- 1/8" - 3/8" or 7-piece set. 7PC Fractional SET - includes 1/8, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8 supplied in a Vinyl Pouch Click here for Specs Note: Sizes 5/32" and 7/32" are made of non heat treated 303 stainless. All other fractional keys made of heat treated 416 Stainless.

Types 416 and 416 Se Stainless Steels have useful levels of corrosion resistance to such media as natural food acids, waste products, basic and neutral salts, natural waters and most atmospheric conditions.

All sizes resistant have been super-passivated for resistance from corrosion of atmosphere , fresh water, food acids and neutral and basic salts.
Note: Metric SS L-Keys are 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.

416 ss and 17-4PH ss, are a martensitic precipitation hardening alloy which offers high strength and hardness while maintaining excellent corrosion resistant properties. RoHS Compliant Products

17-4 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 17-4 are totally unsuitable for marine or other chloride exposure.

416 ss, and 17-4 ss alloys are magnetic.
