GolfSpy Barbajo Posted January 10, 2015 Share Posted January 10, 2015 Been researching online - always a dangerous thing to do - about carbon steel, alloys and forgings. Have some questions.... 1. Learned the difference between 1020 carbon steel and 8620 carbon steel. The xx20 indicates the carbon content of the steel in hundredths. Both 8620 and 1020 have the same amount of carbon - .20%. 2. The first two numbers tell more of a story. The 10xx represents a simple carbon steel that is not alloyed. 86xx indicates an alloy, with a few more ingredients. 3. Apparently, the biggest difference is in hardness - 8620 is a little harder, therefore more durable. From what I was able to find, a golf iron made of either can still be bent the same. The question is - a "forged" iron made from 8620 carbon steel - is it really forged? From what I've read, 8620 can be forged at temps between 1800 and 2200 degrees, but are they typically cast and then stamp-forged? Another question - does it matter? Can you feel the difference? My two cents - yeah, it counts as forged, no, it doesn't matter to me that it's called "forged" when it's cast first and then forged and no, I doubt I could feel the difference. What say youse guys?
