Carbon Steel
Used in either irons, wedges and putters, carbon steel has been used in golf clubs for centuries. Most will associate carbon steel irons and wedges to be forged, as this was the primary method of fabricating these clubs. However, certain alloys of carbon steel can be cast as well (8620 carbon steel) to produce a club head. Regardless, carbon steel is a soft, malleable material that will rust without some sort of protective chrome finish.

More skilled golfers tend to gravitate toward models made of carbon steel as some say that can tell a difference in the feel of the material verses the harder stainless steel. More importantly, head made of softer, carbon steel tend to be less of a game improvement design and are tended more for the lower handicapped golfer.

Many blade-style (non-cavity) wedges are made from different grades of carbon steel.
