Hard steel alloy used in driver club heads and some irons.
Material used in clubhead design with increased amounts of nickel allowing the steel to undergo advanced heating techniques achieving a hardness greater than titanium.
A steel alloy harder than are non-maraging steels such as 17-4 and 15-5. Maraging steel is commonly used in club face applications, rather than in entire club heads.
Special hardened steel used in fabrication of centrifuge rotors and rocket motors. Typically, gas centrifuge programs seek a controlled 350 grade maraging steel.
Extremely hard alloy commonly used in woods as face inserts.
A high alloyed steel that is hardened by both martensite transformation and by age hardening. See Age Hardening, Martensite.
Maraging steel is an iron alloy which is known for possessing superior strength without losing malleability. The iron base is alloyed principally with a large percentage of nickel to produce a very specific heat-treatment product. Other alloying elements include molybdenum, aluminum, copper and titanium and are added to produce intermetallic precipitates.
