Description

本発明は、一種のステンレス合金に関する。特に一般のステンレス合金より比重が小さく、ゴルフクラブのヘッドに応用して、その性能を向上させることができるゴルフクラブのヘッド用ステンレス合金に係る。   The present invention relates to a kind of stainless alloy. In particular, the present invention relates to a stainless steel alloy for a golf club head that has a specific gravity smaller than that of a general stainless steel alloy and can be applied to a golf club head to improve its performance.

一般のステンレス合金は適当な、比率のクロム(Cr)、ニッケル(Ni)、マンガン(Mn)、ケイ素(Si)、炭素(C)、イオウ(S)、リン(P)などの元素により構成される。その比重値(g/cc)は約8.0±0.5で、硬度(HRB)は約89〜95である。例えばType304のステンレス鋼は18〜20%のクロム(Cr)、8〜10.5%のニッケル(Ni)、2.0%のマンガン(Mn)、10.%のケイ素(Si)、0.08%の炭素(C)、0.03%のイオウ(S)、0.045%のリン(P)により構成され、その比重値は8.0で、硬度値は89〜100である。
ステンレスは良好な耐蝕性を備え、かつその硬度値などの条件がゴルフクラブヘッドの関連要件に適合するため、現在では多くのゴルフクラブメーカーがクラブのヘッドをステンレス材質により製造している。
ゴルフクラブのヘッドは種類、形式、角度、用途の差異により一定の番号を配するが、各番号のクラブヘッドには一定範囲の重量、角度の制限がある(例えば、5番アイアンのヘッドの重量上の制限は254gと規定されている)。
一方、使用者のグリップの方式、姿勢の癖、スイングの速度などはすべてそれぞれ異なるため、ボールを打ち出す方向に左右偏移の状況が見られがちだが、これはクラブヘッドの重心位置が良くないか、或いは重心位置が使用者の使用習慣に適していないためである。そのため、メーカー(或いは使用者)は錘を増加する方式により重心の問題を解決しようとして来た。しかし一般に錘を増加する方式はクラブヘッド規定の特定重量の制限を受けざるを得ず、また錘の重量が不足すると、ボールを打撃する時に満足なインパクト効果が得られない。
特公平6−99775号公報
General stainless steel alloys are composed of appropriate elements such as chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), carbon (C), sulfur (S), and phosphorus (P). The Its specific gravity (g / cc) is about 8.0 ± 0.5, and its hardness (HRB) is about 89-95. For example, Type 304 stainless steel is 18-20% chromium (Cr), 8-10.5% nickel (Ni), 2.0% manganese (Mn), 10.% silicon (Si), 0.08% carbon (C). , 0.03% sulfur (S), 0.045% phosphorus (P), the specific gravity value is 8.0, and the hardness value is 89-100.
Since stainless steel has good corrosion resistance and conditions such as its hardness value meet the relevant requirements of golf club heads, many golf club manufacturers are now producing club heads from stainless steel.
Golf club heads are assigned a certain number depending on the type, type, angle, and application, but each number of club heads has a certain range of weight and angle restrictions (for example, the weight of a 5 iron head). The upper limit is stipulated as 254g).
On the other hand, the user's grip system, posture habit, swing speed, etc. are all different, so it is easy to see the situation of lateral shift in the direction of hitting the ball, but this is the center of gravity of the club head is not good Alternatively, the position of the center of gravity is not suitable for the user's usage habits. Therefore, manufacturers (or users) have tried to solve the problem of the center of gravity by increasing the weight. However, in general, the method of increasing the weight has to be restricted by the specific weight specified by the club head, and if the weight of the weight is insufficient, a satisfactory impact effect cannot be obtained when the ball is hit.

公知構造には以下の欠点があった。
すなわちゴルフクラブ使用者のグリップの方式、姿勢の癖、スイングの速度などはそれぞれ異なるため、ボールを打ち出す方向が左右に偏移する傾向が見られるが、これを解決するため、メーカー(或いは使用者)は錘を増加する方式を選択して来た。しかし一般に錘を増加する方式はクラブヘッド規定の特定重量の制限を受けざるを得ず、錘の重量が不足していれば、ボールを打撃する時に満足な効果が得られない。
本発明は上記構造の問題点を解決したゴルフクラブのヘッドに応用するステンレス合金を提供するものである。
The known structure has the following drawbacks.
In other words, the golf club user's grip method, posture habit, swing speed, etc. are different, so there is a tendency that the direction of hitting the ball shifts to the left and right, but in order to solve this, the manufacturer (or user ) Has selected a method to increase the weight. However, in general, the method of increasing the weight is inevitably restricted by a specific weight specified by the club head. If the weight of the weight is insufficient, a satisfactory effect cannot be obtained when the ball is hit.
The present invention provides a stainless alloy that is applied to a golf club head in which the above-described structural problems are solved.

上記課題を解決するため、本発明は下記のゴルフクラブのヘッドに応用するステンレス合金を提供する。
それは主にステンレス合金を提供し、該合金は一般のステンレス合金に比べ比重値が低く、ゴルフクラブヘッドの製造に用いられ品質を向上させることができることを特徴とするゴルフクラブのヘッドに応用するステンレス合金である。
In order to solve the above-mentioned problems, the present invention provides a stainless alloy applied to the following golf club head.
It mainly provides a stainless steel alloy, which has a lower specific gravity value than a general stainless steel alloy, and can be used for manufacturing a golf club head to improve its quality. It is an alloy.

上記のように、本発明はゴルフクラブのヘッドの材質を同一の体積、硬度の条件下で、その比重値を低下させ、その錘の重量、範囲を増加させ、さらには同一のクラブヘッドの硬度、重量により、クラブヘッドの体積を増加させることにより、クラブヘッドの打球効果を向上させることができる。すなわち本発明のステンレス合金はより低い比重値を提供することにより、ゴルフクラブヘッドの成型、製造に応用され、クラブヘッドの品質を向上させることができ、極めて高い産業利用性を具える。   As described above, the present invention reduces the specific gravity value of the golf club head material under the same volume and hardness conditions, increases the weight and range of the weight, and further increases the hardness of the same club head. By increasing the volume of the club head by weight, the hitting effect of the club head can be improved. That is, the stainless steel alloy of the present invention can be applied to the molding and manufacturing of a golf club head by providing a lower specific gravity value, and can improve the quality of the club head and has extremely high industrial applicability.

本発明のステンレス合金は、Mn29〜33%、A17.5〜11%、Cr1.5〜3.5%、Si0.8〜1.2%、C0.4〜0.8%、S0.03%、P0.06%、残部鉄Feにより構成する。
上記の成分構成のステンレス合金の硬度値は85〜95で、比重値は7.0±0.5である。
上記ステンレス合金はゴルフクラブヘッドの製造に応用され、比重値が低いため、クラブヘッドの外観形状、重心など設計の幅を拡大することができる。
すなわち、304ステンレス合金(比重値は8.0)により製造する5番アイアンのヘッドの重量は254gであるが、本発明のステンレス合金(比重値7.0) により製造する5番アイアンのヘッドの重量は254gとなる。そのため、クラブヘッドの体積が同一とすれば、304ステンレス合金により製造する5番アイアンのヘッドの重量は254gであるから、本発明のステンレス合金により製造する5番アイアンのヘッドの重量は222.25gとなる。
すなわち、254g(304ステンレス合金クラブヘッドの重量)÷8(304ステンレス合金の比重値)×7(本発明ステンレス合金の比重値)=222.5g(本発明ステンレス合金クラブヘッドの重量)であって、304ステンレス合金クラブヘッドの重量−本発明ステンレス合金クラブヘッドの重量=31.75gとなる。
31.75÷254=12.5%(本発明が増加可能な錘の重量のパーセンテージ)であるから、体積が同じであるという条件において、本発明のステンレス合金により製造するクラブヘッドは一般のステンレス合金により製造するクラブヘッドに比べて規格上重さ12.5%分に相当する余地があるということができる。
言い換えれば、本発明の低比重のステンレス合金は一般のステンレス合金に比べクラブヘッドの重さが同一であるという条件下でいえば、クラブヘッドの体積を増加させることができ、クラブヘッドの設計の自由度を向上させ、クラブヘッドの品質を高めることができる。

Stainless steel alloy of the present invention is Mn29-33%, A17.5-11%, Cr1.5-3.5%, Si0.8-1.2%, C0.4-0.8%, S0.03%, P0.06%, It consists of the remaining iron Fe.
The hardness value of the stainless steel alloy having the above component structure is 85 to 95, and the specific gravity value is 7.0 ± 0.5.
The above stainless steel alloy is applied to the manufacture of golf club heads and has a low specific gravity value. Therefore, the design range such as the external shape and center of gravity of the club head can be expanded.
That is, the weight of the head of the No. 5 iron manufactured by 304 stainless alloy (specific gravity value is 8.0) is 254 g, but the weight of the No. 5 iron head manufactured by the stainless alloy of the present invention (specific gravity value of 7.0) is 254 g. Become. Therefore, if the club head volume is the same, the weight of the head of the 5 iron manufactured from 304 stainless alloy is 254 g. Therefore, the weight of the head of the 5 iron manufactured from the stainless alloy of the present invention is 222.25 g. Become.
That is, 254 g (weight of 304 stainless alloy club head) ÷ 8 (specific gravity value of 304 stainless alloy) × 7 (specific gravity value of the stainless steel alloy of the present invention) = 222.5 g (weight of the stainless steel alloy club head of the present invention), Weight of 304 stainless alloy club head−weight of stainless steel club head of the present invention = 31.75 g.
Since 31.75 ÷ 254 = 12.5% (percentage of weight by which the present invention can be increased), the club head manufactured by the stainless alloy of the present invention is manufactured by a general stainless alloy under the condition that the volume is the same. It can be said that there is room for 12.5% weight in comparison with the club head.
In other words, the low specific gravity stainless steel alloy of the present invention can increase the volume of the club head under the condition that the weight of the club head is the same as that of a general stainless steel alloy. The degree of freedom can be improved and the quality of the club head can be improved.
