keybs Posted November 5, 2006 Report Share Posted November 5, 2006 As I've been looking for new irons for the past few months I've been trying to decipher the codes to these different types of metals used in some of the clubs being sold today. It would be great if someone could put together a chart of the different grades of metals from good to bad or hard to soft with composites included so buyers would have someway of understanding what they're getting themselves into. Does anyone know how to compare these? S25C OR 1020 carbon steel or 1018 carbon steel.....what does it really mean? :tsg_smilie_confused: Quote Link to comment Share on other sites More sharing options...

+TourSpecGolfer Posted November 8, 2006 Report Share Posted November 8, 2006 KZG has a good discription about the right way to make golf clubs. "Carbon steel bars are first heated to 1,200°C+ then struck with a 4-ton air hammer containing the tooling die. The newly formed head is trimmed, cooled and blasted to remove burrs. Then the head is reheated to 800°C for a second forging using a half ton air hammer and again cooled and blasted for burrs. This double-forging process not only eliminates the voids typically found in other forgings, but compresses and aligns the molecular structure in the carbon steel. There is no more consistent and precise method of making a golf club. Each head is individually shaped and ground to exacting specifications by master craftsmen, then stamped, painted, polished, buffed, finished, and plated." ok so everyone knows that cast clubs are made from a mold and forged comes from a heavy press with a die or master. the number 1018 is pretty much the softest carbon metal used in irons like scratch and ishihara, 1020 is and has been used by epon, miura, etc, 1025 is used by Mizuno and most others. It goes way up as wishon uses 1045 for his forged cavity backs. Finish, Design, Shaft & Grip, and other factors play an almost bigger role than the number. Raw 1018 vs Raw 1045 i can tell the difference. but 1018 vs 1025 i cant due to many variables. Japan uses different numbers than USA does i.e 1025C is S25C or was it vice versa, I dont know i have seen both methods used in Japan. if i left anything out or im wrong about somthing please correct me someone :tsg_smiley_yes: Quote Link to comment Share on other sites More sharing options...

ramizuno13 Posted November 8, 2006 Report Share Posted November 8, 2006 Chris, S25C(also S20C, ect...) is proprietary to Japan(or was). It is heat-treated different than 1025C. It is said that it "Feels" softer. Quote Link to comment Share on other sites More sharing options...
