Steel iron shafts have dominated the golf marketplace for 75 years. The reason: Consistency and stability. The process for manufacturing steel shafts is easily repeatable, and the performance from one shaft to another is highly predictable.
According to Nippon, the N.S. Pro 950GH is its best selling shaft. It often is cited as the first modern lightweight steel shaft. The hallmark of the 950GH is its combination of strength and weight. The strength comes from a lightweight alloy called NSGS8665V.
These shafts are sold only through Nippon’s network of custom clubmakers, and the shaft price varies with the composition of the set for each golfer.
Steel shafts from True Temper and Nippon are available down to the 75-gram range, although individual golfers must decide how light is too light. On the PGA Tour, where swing speeds are among the fastest in the world, more than 95 percent of players use steel iron shafts. Traditionally, skilled players have favored heavier weights – in the 120- to 130-gram range – but interest in lighter weight steel is increasing on Tour and among amateur golfers
