Good question. I have no idea what they use in shavers but the steel used in single edged blades is some kind of high carbon because it will rust. As a paper hanger for the last 16 years, I go through many boxes of single edge blades every year and for most of the day have one hanging out of my mouth. I should know for a fact what kind of steel they use by now shouldn't I?:D
 
I believe that the blades on the Mach 3 are coated. If you're really interested, you might want to email BF member Darrell Lewis (username: DarrellGLewis); IIRC the conversation correctly, the company he works for does the coating.
 
I used to work with a retired Navy chief who swore up and down that Gillette bought old retired aircraft carrier decks. He claimed that the steel used on the deck was the highest quality, and that's what we now shave with.

Was he pulling my leg? Maybe, he liked to tell stories, but this one might be true...
 
It's more likely that Gillette and other companies buy gigantic rolls of flattened wire and pull them through some sort of machinery that sharpens them and heat treats in a continuous assembly line. At some point they are then chopped up and injection molded into the handles or what have you.
 
12c27 is a Swedish steel that is occasionally encountered in knives. If I remember correctly, its composition is similar to 440C.
 
Sandvik 12C27 is a martensitic stainless chromium steel with an optimised analysis for high quality professional knives application. After heat treatment the composition of carbon and chromium gives a unique combination of properties including:
- Very high hardness
- Good corrosion resistance
- Very good wear resistance

This grade is also suitable for
- hunting and fishing knives
- pocket knives
- skate blades and ice drills { ...Guess the "Cast Away" character played by Tom Hanks had a 12C27 skate-blade-Axe!}

Carbon= 0.6% / Chromium= 13.5 % (No other elements are listed; probably not deemed important on ther lists...)
Source: Sandvik Web Site.
HOWEVER, notice the list of uses does NOT include razor blades, per se... if they made zillions of razor blades out of it, they'd probably mention it.
HOWEVER... their site DOES say that 13C26 Steel IS USED for Razor Blades... Carbon 0.68% / Chromium = 13.0 % (undisclosed auxiliary elements.)
So Shave Away!

My steelsheet tells me that 12C27 also contains 0.4% Mn and 0.4% Si. 13C26 contains 0.65% Mn and 0.4% Si.
 
Gillett's Mach-3 Razor blade is made of 440A High Carbon .7 to .75 Caron. Starting with coil stock then Fine Blanked to shape but remaining in coil form until after Heat Treating and Grinding. The blades are scored during fine blanking and broke apart for coating.
The Coating on the Mach-3 is of Chromium Base CrN with a DLC or Diamond Like Coating on as a Top Layer.This process is a batch type coating using Physical Vapor Deposition (Sputtering)
