Hello everyone. I'm looking for major razor blade producers and the most commonly used razor blade grades. I believe it is the 13CrMn grade that is commonly used. Is there a ATSM designation for these stainless razor blades ?( i.e. 304 , 430 etc.). Also can you kindly suggest who the major razor blade producers would be ? Will it be the stainless steel mills or other players?

Thanks!
