Abstract
A golf club head is integrally made of aged martensitic steel by precision casting and features high striking effect and better hand feeling. Said aged martensitic steel contains Ni, Co, Mo, Ti, Al and Fe.
Description
The present invention proposes the golf club that a kind of maraging steel is made.
At present, golf club is generally made of stainless steel or titanium alloy, because these two kinds of peculiar performances of metallic substance make the golf ball strike effect not reach optimum regime as yet.
The objective of the invention is to propose a kind of golf club of making of the martensitic aging steel, its strike effect is good, and far away than existing golf club hitting distance under same hitting power, player's sensation is better.
The present invention seeks to realize like this: maraging steel has following four kinds, and first kind is 18Ni type maraging steel, and the weight percent of its various elemental compositions is: nickel: 17-19, cobalt Co:8-13, molybdenum Mo:3-5, titanium Ti:0.1-1.6, aluminium Al:0.1-0.2, iron Fe: surplus.Second kind of few Ni do not have Co type maraging steel, and the weight percent of its various elemental compositions is: nickel: 6-8, manganese Mn:3-5, molybdenum Mo:3-5, aluminium Al:0.1-0.2, iron Fe: surplus.The third stainless type (not conforming to Co) maraging steel, the weight percent of its various elemental compositions is: nickel: 8-13, chromium Cr:4-18, molybdenum Mo:2-4, aluminium Al:0.03-1.0, titanium Ti:0.1-0.3, iron Fe: surplus.The 4th kind of stainless type (containing Co) maraging steel, the weight percent of its various elemental compositions is: nickel: 7-12, chromium Cr:8-13, molybdenum Mo:2-6, titanium Ti:0.1-1.0, iron Fe: surplus.More than four kinds of materials make golf club by precision casting monolithic molding legal system.
The invention enables the player under same hitting power, the golf ball farther distance that can fly out, strike effect is good, and feel was comfortable when the player was hit.Simultaneously present titanium alloy (Ti-6Al-4V) golf club, the tensile strength sigma of its material
b=1015MPa, σ
5=945Mpa, HRC30, and martensite aged stainless steel σ
b=1500MPa, σ
8=1300MPa, HRC48 this shows, the performance of martensite aged steel golf ball head all is higher than the titanium alloy bulb.
Embodiment 1:
Adopt 18Ni (350ksi level) maraging steel to make golf club, close whole world head with titanium and compare performance and significantly improve.The material tensile strength sigma
b=2400MPa, σ
2=2350MPa, δ=6～7%, HRC56～58.
Embodiment 2:
Adopt Ma Minti aged stainless steel (not containing Co) to make Gao Er head shoot head, its material σ
b=1600MPa, σ
2=1500MPa, δ=10～20, HRC45～47.
Embodiment 3:
Adopt martensite aged stainless steel (containing CO) to make golf club, its material σ
b=2450MPa, σ
2,=2400MPa, δ=6～10%, HRC48～50.
Claims (4)
