to cast into all the shapes that you see golf clubs made plus durable enough for everyday play.There are two main types of stainless steel used in golf club heads. One is 17-4 stainless steel (comprising of no more than 0.07% carbon, between 15 an 17% chromium, 4% nickel, 2.75% copper, and 75% iron and trace elements). 17-4 used primarily for metal woods, hybrids and some irons. The other type of stainless steel is 431 (comprising of no more than 20% carbon, 15-17% chromium, 1.25 – 2.5% nickel, and the remainder being iron and a few trace elements). This grade of stainless steel is used for irons and putters.

The majority of fairway woods today are manufactured from 17-4 stainless steel. Drivers can also be made of 17-4, but due to the high density of the material, the limit on size is approximately 250cc without the risk of cracking during normal play. Because golfers prefer larger, easier-to-hit drivers, few drivers today are even manufactured from stainless steel Investment cast irons can be made from either 431 or 17-4 grades. The 17-4 is slightly harder
