The 431 stainless steel on the Nike CCi irons are cast using a 25% softer material than the more common 17-4 stainless steel. Incorporating a thicker topline with more offset than the forged irons allows for more forgiveness and straigter ball flight for those that are prone to hitting a slice. The wider soles on the Nike CCi irons aid in getting the ball up in the air quickly. The CCis made the 2007 Golf Digest Hot List.
